I just downloaded Visual Studio Code and my Intellisense is not automatically working.
The two settings that control this seem to be set correctly:
"editor.quickSuggestions": true,
"editor.suggestOnTriggerCharacters": true,
I do get an Intellisense menu when i start typing and press "CTRL + Space", but this gives me a list of everything and not things specifically for my object.
What am i doing wrong?
If you have a workspace and for some reason have multiple folders you may need to 'help' omnisharp a bit. I initially had a big project and added a solution for it further on - ending up with TWO workspace folders (one to a startup project and one to the solution). After composing that setup I experienced only the first project to have intellisense working.
Solution to get intellisense working was to make sure omnisharp worked its way from the solution instead of the project:
Ctrl + Shift + p
Write "OmniSharp: Select Project" and press Enter.
Choose the solution workspace entry.
Inspiration gotten from 'swaner':
https://github.com/OmniSharp/omnisharp-vscode/issues/1889
Visual Studio Code's more advanced editing features (IntelliSense, refactoring tools, etc.) only work in C# files if you have a project.json file or *.sln file that VSCode is aware of. Open the folder (i.e. open the File menu and click Open Folder...) with the *.sln file or project.json and VSCode will attempt to find all project/solution files in the folder. If there are multiple projects, you may need to select one from the projects button on the right side of the status bar (bottom of the window).
From the VSCode website:
Selecting a project.json-file is opening a DNX-project and VSCode will load that project plus the referenced projects
Selecting a *.sln-file is opening a MSBuild-project. It will load the referenced *.csproj-projects and sibling or descendant project.json-files but no other project files that are referenced from the solution file.
Selecting a folder will make VSCode scan for *.sln and project.json files and VSCode will attempt to load them all.
If you are start your project with c#, then some time you haven't download extension.
Process by written
Ctrl + Shift + p.
Write "OmniSharp: Select Project" and press Enter.
Choose the solution workspace entry.
Then enable the c# extension for "OmniSharp : Project".

Downgrading to 1.23.9 of the C# VS Code extension fixed the intellisense for me. So if nothing else is working for you, perhaps try installing an older version of the extension (doesn't necessarily have to be that exact one I mentioned). You can do this by selecting this option in VS Code:
As of the 0.5 version I have found that I need to close and re-open my working files to get some new intellisense information to start working for my own files. This usually happens after I have a file open that needs to use type information from another file I just created. Until I close and re-open them (within the editor) the intellisense doesn't always work.
Hopefully this is something that'll get fixed as the app matures.
Inorder to make the intelligence working, the Visual Studio Code extension OmniSharp should be there along with Mono. When you open a project/solution folder, the OmniSharp gets the project dependencies from either project.json or from the dotnet solution file (if the project/solution created with other versions of visual studio).
So, when you look at the omnisharp's output window after immediately opening the project/ solution folder, you may see the following lines
Starting OmniSharp server at 2017-9-18 09:26:44
Target: /Users/{username}/Source/{Your Solution Folder}/{Your Solution
file}.sln
OmniSharp server started wth Mono
Path: /Users/{username}/.vscode/extensions/ms-vscode.csharp-1.12.1/.omnisharp/run
PID: 5808
post that, you may see couple of lines coming up like below,
[info]: OmniSharp.MSBuild.MSBuildProjectSystem
Update project: {Your Project1 Name}
[info]: OmniSharp.MSBuild.MSBuildProjectSystem
Update project: {Your Project2 Name}
....
they mean that your projects are getting recognised by OmniSharp Extension.
If you get any error message informing you about timeout, please get into the settings of the Visual Studio Code, and add a configuration override like the one below:
"omnisharp.projectLoadTimeout": 200
I know it is too long to wait for 200 seconds. But don't worry, this won't stop you anymore working with project files. But, remember that the IntelliSense will be automatically available once all the projects in the folder are successfully loaded.
Feel free to extend the Timeout setting since it will help you getting intellisense even-though you are not getting it immediately.
Here is another link with the same solution: https://github.com/OmniSharp/omnisharp-vscode/issues/1585
Hope my information helps you! Enjoy your VSCode!
This case was for an existing project that was working fine before. Opened via the vs code "recent" history.
For dotnet core. I opened my project's *.csprog file, made no changes, and saved it via the vs code editor.
As soon as I saved, all of the intellisense stuff starting working again in my other files within that project.
Another troubleshooting strategy to try if none of the above works out is uninstalling Mono, which is unnecessary anyways if you're using .NET Core. I also experienced a sudden disappearance of Intellisense after pulling changes to one of our enterprise repos that included an upgrade from ASP.NET Core 2.0 to 2.1. Strangely, at the same time, Intellisense was working fine in another C# project repo running ASP.NET Core 2.2.
For the project in question, I was puzzled to see successful logs for each reboot of the Omnisharp server as well as perfectly clean builds and runs. The puzzlement increased as I compared these Omnisharp logs to those from the 2.2 project and found them effectively identical.
Upon uninstalling Mono, the one detail that changed is how Omnisharp started. Now it boots up from a shell script located at ~/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/run. Previously, Mono itself was booting the server from the executable at ~/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/omnisharp/Omnisharp.exe.
Other troubleshooting I attempted in this instance though to no avail:
dotnet clean / Deleting bin and obj directories
Updating launch.json to point at the proper /bin/Debug/netcoreapp2.1 build
directory
Wiping my local nuget cache
Restarting Omnisharp
Uninstalling and reinstalling VS Code, as well as bumping back a version from 1.33.1 as the breakage coincided oddly with the March 2019 update
Uninstalling and reinstalling the C# VS Code extension, as well as bumping back a version from 1.19.0 given other users' reports of said version interfering with Intellisense for certain projects*
Adding a global.json file at project root to override default utilization of latest .NET Core SDK (mine was 2.2.105) and run instead using 2.1.302 in concert with the project's version
Wiping/rebuilding the project .sln file
Specs: VS Code 1.33.1, C# Extension 1.19.0, MacOS High Sierra 10.13.6.
*NB: As it turns out, in another .NET Core 2.1 project with the same issues in VS Code as described above, uninstalling Mono alone did not fix things. I also did wind up needing to bump back the C# extension to v. 1.18.0 to recover Intellisense. Weird.
The issue I had was OmniSharp was an older version. I set the flag to update to latest version in Settings.json file. This ensures the extension is always the latest version.
"omnisharp.path": "latest"
And restarted VS code. That fixed it for me.
Simply reinstall the extension and restart the VSCode/PC.
I use Task Manager and kill the Visual Studio Code process, then restart Visual Studio Code, the intellisense shows and fixed.
I've had some good experiences in C# with this extension so far:
https://marketplace.visualstudio.com/items?itemName=jchannon.csharpextensions
This extension traverses up the folder tree to find the project.json or *.csproj and uses that as the parent folder to determine namespaces.
Try "Install Extension" from command Pallete - probably if C# intellisense is not there:
https://code.visualstudio.com/docs/customization/colorizer
if intellisense in not working for react js or javascript or node js this solution will help for windows
uninistall type script by typing npm uninstall -g typescript
install specific version of type script that is 3.3 by typing npm install -g typescript#3.3
add the typescript location in vscode by navigating to file > Preferences > settings > here search for edit in setting.json then add this path "typescript.tsdk": "/Users/yourusename/AppData/Roaming/npm/node_modules/typescript/lib"
settings.json should look someting like this
{
"editor.suggestSelection": "first",
"vsintellicode.modify.editor.suggestSelection":"automaticallyOverrodeDefaultValue",
"typescript.tsdk": "/Users/yourusername/AppData/Roaming/npm/node_modules/typescript/lib"
}
I was able to fix this by changing the Api Compatibility Level from .Net Standard 2.0 to .NT 4.x. You can find this setting on Project Settings / Player.
After that, intellisense started working again.
This is because of C# extension issue.
Reinstall the extension will work.
https://code.visualstudio.com/docs/editor/intellisense
https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csharp
I fixed this with a multiple project solution in .net5 / .net core 3.1 by
opening each project (not the sln folder) in VSCODE. This then prompts to add the resources/ .CSX? files to the project; enabling intellisense, per project. Finally close that window and reopen the solution folder and all works as expected.

Downgrading to 1.23.9 of C# for Visual Studio Code (powered by OmniSharp).
https://i.stack.imgur.com/VrdJl.png
After trying several things I looked at the OmniSharp logs only to realize that because I had two different sln files in my workspace. It had picked up the “other” one and thus wasn’t working. I deleted it, reopened vs code, and all is well again.
For me I had been working without internet for a long time. It had previously been working but then stopped. I closed+reopened VSCode with a stable wifi connection and the Output tab in VSCode popped up, displaying the the extensions were re-installing. After that it worked!
in my case , the extension wasn't enabled
I just had this happen (this being no code completion suggestions appearing). What resolved it for me was changing the VSCode Editor package in Unity to a previous version and then back to the current version.
For me, this was going from 1.2.0 to 1.1.3 and then back to 1.2.0. I believe removing and reinstalling 1.2.0 would have accomplished the same.
Window > Package Manager > Visual Studio Code Editor
I know this is probably the most obvious answer. But I had enough dealing with VS Code ridiculous bugs. You should be focusing on code, not the buggy IDE. Their documentation doesn't make it easy either to debug.
Steps for complete uninstallation:
Save your personalization files such as keybindings.json,
Just put it on GitHub or something so whenever you need have trouble with VS Code you simply just need to go to GitHub and copy-paste it.
Uninstall VS Code completely
When you uninstalled VS Code, it doesn't erase your extension files and some old settings. This is the cause of the re-installation ended up the same. Horrible move VS Code. For the list of the files that you must delete, you can check out this answer.
Go to their website and install the new one.
I hope this helps some people who are already had enough with the VS Code ridiculous bug.
In my case, the issue was not with VS Code settings. The error was due to a corrupted TEMP path configured in my PC's registry user profile environment settings.
I got this error from Help --> Toggle Developer Tools --> Console
The error was flagged in the console when I opened a new typescript file.
Unable to write file c:\Users\XXX\AppData\Local\Temp;C:\wamp64\bin\php\php5.6.25;C:\vufind-3.1.2\install.php\09cf49d8-af5b-42e9-8194-43f5b566be0f'
Obviously this path was corrupted. After updating the environment variables in registry settings, the VS code IntelliSense started working. Checking the console is a good start to find the root cause of this issue.
Earlier intellisense was working for Angular in VS-Code but for some reason (which I don't know) intellisense stopped working. I had extensions installed i.e. Angular Essentials and Angular Language Service etc. that were responsible for this intellisense and all that.
What I did?
I disabled the extensions, restarted VS Code and enabled them. It was all working fine as before.
If everything in VSCode is working ( No errors in output console, language server is working etc.) and built-in extensions are enabled. Still, if your IntelliSense is not working for normal .js files make sure variables are defined with a type identifier such as var d = new Date() or let d = new Date(). In my case, IntelliSense was not working for d = new Date() (No autocomplete for Date object 'd' APIs in this way) but started working fine when I specified a type before my variable names.
Download and install "Tool for Visual Studio 2019" as the C# extension under hood use the build tools: https://visualstudio.microsoft.com/downloads/
In my case, I had an extension installed (Explorer Exclude) to help me focus and hide certain files that I don't regularly work with within the Explorer.
I so happened to have disabled viewing *.sln, *.csproj and *.vsconfig files and folders, which apparently prevents VSCode from even knowing the file is there in the first place. Disabling these specific rules solved the problem instantly.
Took me ages to figure out... The more you know.
I solved it by uninstalling all SDK's (not sure if this is needed)
and installed 4.7.1 developer pack
win 10, vscode 1.63.2, unity 2020.3.25f1
I fixed this by installing .NET Framework 4.7.1 Developer Pack:
https://dotnet.microsoft.com/en-us/download/dotnet-framework/net471
I'm running my .NET 4.0 (C#) project in debug mode after I start VS2013. It runs just fine.
The second time I start it from VS, I get the Dialog box that says "Error while trying to run project: Unable to start program C:\path\to\file.exe"
The process is still alive in the Taskmanager when I dismiss the dialog box.
From Windows Explorer, I can run the program just fine. And after closing it, the process is gone too from the Task Manager.
A rebuild doesn't help.
Is this a common problem with a known solution?
I had an issue similar to this and I had to clear the component cache instruction can be found Here.
Hope this helps.
For my case, it cause by Platform target, you could force choose it to x86 or x64 which your project is:
Each Project's Properties > Build > Platform target
As I pointed out also here, the only solution that worked for me was to disable the ConEmu integration:
ConEmu → Settings → Integration → Default term → disable Force ConEmu as default terminal for console applications
Some users reported that it was enough for them to disable the Aggressive mode in that same settings tab; that wasn't the case for me though.
The topic is old, but this might help someone else.
So in my case I made a file in Visual Studio with .cp extension (accidentally deleted the last 'p') this made visual studio just "include" the the file and not mark it as a compilation unit, thus not compiling it, I looked the *.vcxproj file in a text editor and found out about this, so if you open the project file in a notepad or something just find your file at the bottom usually and change from <Item .../> to <ClCompile .../>
I was getting similar errors. I just had to restart visual studio. Sometime couple times a day.
I had a similar error and resolved it by cleaning the solution. Right-click the solution name in Solution Explorer and choose Clean Solution.
I found a solution here:
Please check "Use Managed Compatibility Mode" under Tools|->Options->Debugging->General.
I'm Brazilian, I don't speak English very well. I did this translation on google translator.
I know the topic is old, but it can still help someone.
I had this same problem in the following situation, I have a dual boot computer (linux debian 11 and windows 10). Inside debian, on my NTFS D disk, I created a folder to perform programming tests. After accessing that same folder with windows, I created a new project in visual studio inside that same folder that I had created in linux. The creation of the project went without problems, however when I tried to run the project (F5), I received the same error from this topic. I tried all the solutions I found on the internet, and nothing worked. I gave all permissions to my admin user and it still didn't work. Then I realized that even going straight to the folder where the application's executable was and clicking directly on it, I still received the access denied error message. So, I took the project out of the folder I had created in linux, and it worked. So, what I could conclude, is that because the folder where my project was was created in linux, for some reason, my windows didn't trust this folder, so it didn't allow running executables from inside that folder, even this one executable having been created by visual studio from within windows.
Just simply create a folder name as "projects" in c drive and copy paste the newly created project in it. Run the project by doing clean & Build or Rebuild method . It will work
open the folder which contains the solution in visual studio.
again, open your *.sln file by double clicking it inside the solution explore once opened try running the solution or rebuild the solution. once rebuild gets completed, it will open without error from next time.
My way of solving the error : error while trying to load project : Unable to start program and c:\Path\to\file.exe was simply by
First restart Visual Studio
Click the build icon
Select the rebuild option
Run the Program or Debug the Program
This was a weird one. Going to put what happened to me here because it might happen to someone else. Everything was fine with the app until suddenly after some fairly insignificant code changes I suddenly started getting this error. Visual Studio was compiling the executable just fine. But, the moment I tried to run it (either from Visual Studio or directly) the executable file would be automatically deleted right out of the Debug folder. Super odd--never seen anything like it. I began to get suspicious that perhaps an anti-virus or the OS was somehow identifying a checksum or some signature in the executable as "dangerous". Or perhaps some obscure compilation bug was corrupting the executable. So on a hunch I made another innocuous change (added a couple of lines of code to color code some text in a rich text box) and the problem went away.
I used to be able to debug using Visual C# Express 2010 with no problem before. However, since I've opened my project using MonoDevelop (to port it under MacOS), I can't seem to be able to debug anymore.
The exact error message is available below:
A lot of people says to go in the configuration manager, which I'm familiar with, however, I can't seem to find it in the Express version.
Since you didn't have this issue prior to opening in Monodevelop, it more than likely changed something within the solution and/or project files. There are a number of posts on stackoverflow...
stackoverflow: no symbols
stackoverflow: no symbols when crossing module boundries
(From Răzvan Panda comment on the question)
... that talk about missing symbols. However, based on the information provided about monodevelop, I'd venture to guess that the IDE changed something within the solution and/or project files.
If your solution is under source control and you don't see any differences in these files, let me know. Otherwise, you could create a new blank solution/project file (from Visual C# Express 2010) and re-add all your files to it to get the default settings back and see if that resolves your issue.
EDIT: Also, keep in mind that there are ".user" files that I guess "might" have an effect on build/debugging configurations. If re-adding your files to blank solution/project files doesn't work make sure all the "extra" files like ".user" are not in the directory. Usually files like ".csproj.user", and ".suo". I've never had an issue deleting these they store local configuration changes that are not usually checked into source control.
I had same problem with Symbols when I added some dll to my project so what I did was to manually adding them. you can try going to tools > option > Debugging > Symbols and from there you can add the file root (in this case monoDevelop) and it automatically looks for all .pdb files and adds them to your environment. After rebuild it should be Okay.
Cheers
As George Duckett said:
Re. configuration manager, enable expert settings first. Tools->Settings->ExpertSettings. Then find it under Build->ConfigurationManager
Then changed it to Debug.
I receive the following error when attempting to Step Into a process using F11 in Visual Studio 2008 Team System:
"Unable to automatically step into the server. The debugger failed to stop in the server process."
I have searched pretty long and hard on the internet and the most relevant message I found was http://msdn.microsoft.com/en-us/library/65004e38%28v=VS.90%29.aspx. Unfortunately, this did not help. All signs are pointing that my ASP.NET setup is incorrect, but it's the IIS environment that ships with VS2008 Team System so I didn't make any figuration changes.
The answer to this question, which sounds like it might have fixed my solution is no longer an active link: Unable to automatically step into the server when debugging WCF. Does anybody know how I can jump into and fix this problem?
This took me 3 days and no less than 5 people looking at the problem to solve; although I'd like to report the exact problem I'm still left to speculate. However, I am no longer getting this error when I do the following:
I opened the .cs file of the base class my service derived from within my Testing solution. I set a break-point in the constructor of this base class. Because the base class wasn't within the solution of either my web service nor my test solution (it was simply referenced), VS2008 was unable to break into this .cs file.
The solution was rather moronic. I opened the base class.cs file within my Testing solution (the file only, not the solution). I set a break-point in the constructor class, and I was then able to step-into all other files from there. Once I was able to successfully set a break-point and stop the debugger in the base class within my actual Test solution, I was able to continue debugging as I would normally expect.
My only conclusion to the root cause of this problem is that VS2008 is retarded. I'm sorry it's not much of an answer, but this is how I was able to resolve the issue which sunk over 30 hours of time.
This could be because the debug not reaching to your break point there may be some error occurring before it.Try add break point in the base class constructor.
I know this is an old question, but I encountered a similar issue and the problem was that I was in Release mode rather than Debug mode. Changing to Debug mode solved the problem. I'm using VS 2010.
this problem can occur if you have another solution opened and running (another instance of visual studio).
I got this error once when I had the wrong project set as the startup project in the solution.
This same thing happened when I had the service open in a browser. I closed it out and it fixed the issue.
Guessing you have it open multiple times. (basically repeating what Avicena00 said)
I got this error when trying to import a file that was too big. I had to increase the maxAllowedContentLength value in my requestLimits area in my web.config to fix it.
As stated this is an old problem, but I ran into it running later versions of Visual Studio, and have not seen the solution that I found listed. This problem in my experience happened when the service was using a lower version of .Net (in my case 3.0 vs 4.5). Changing the .Net version int he project properties to 4.5 (which matched the project referencing the service), solved my problem.
This worked for me: Tool > Options > Debugging > Use Managed Compatibility Mode
Visual Studio 2018 Options
In my case the problem was that I had open the same project and its copy (in different directory) in two Visual Studio instances. Solution than in final was simple as closing all IIS instances of Web projects and closing all instances of Visual studio. After opening just one project at a time debugging started to work like a charm.
I get this error when I debugged one and another solution.
The answer is very simple
Click on the solution->Properties->Multiple startup projects
Then select projects and click f11.
I am having great difficulty getting a Windows program, written in VS 2008 C#, to launch another type program. I've put a main program to offer you the ability to launch some other VS 2008 C# programs. When one of them is selected the following code is intended to do the launch:
System.Diagnostics.Process.Start(#"C:\Documents and Settings\rat\My Documents\Visual Studio 2008\Projects\PV_002_082708\PV_001\PV_001\bin\Debug\PV.exe");
It works, but each user will have a different path. The path shown is for my computer. The code would have to know where each persons program was installed! In the past, I could easily call a program that was in the C:\Program Files location because that's where the MS Package & Deployment program put the programs. VS 2008/2010 doesn't put them there!
I'm sure I am not knowledgeable about Visual Studio 2008/2010 to know if there is a way around this, so any help would be greatly appreciated.
System.Diagnostics.Process.Start(System.Io.Path.Combine(System.Windows.Forms.Application.StartupPath, "PV.exe"));
assuming that the program is in the launched application's path.
or...
System.Diagnostics.Process.Start(System.Io.Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments), #"Visual Studio 2008\Projects\PV_002_082708\PV_001\PV_001\bin\Debug\PV.exe"));
assuming you want to open the project from it's place.
Once you create the installation package you can set the install path to some fixed path that users will not be able to change and than use that from your code (not very user friendly but it would work) or insert the user chosen path value into the registry and get it from there instead.
May want to have a look at this thread. How-to as well as lots of pro's and cons.
Embedded a *.exe into a dll
If you see the first answer to his question, I think this would work for you.
Simply he is saying, you add a resource file to your project, then when the user runes your program, it extracts your exe file that you added as a resource file to somewhere you know on the end users maching.
