I am trying to reset every single setting inside Visual Studio as I have completely lost all IntelliSense. I tried the Tools -> Import/Export settings -> Reset, but that is not clearing all the settings. I know it is not since the color theme was not reset, and I still do not have IntelliSense. Short of uninstalling and deleting every trace of the program including the registry, is there another way to reset every single setting to the factory default?
Visual Studio has multiple flags to reset various settings:
/ResetUserData - (AFAICT) Removes all user settings and makes you set them again. This will get you the initial prompt for settings again, clear your recent project history, etc.
/ResetSettings - Restores the IDE's default settings, optionally resets to the specified VSSettings file.
/ResetSkipPkgs - Clears all SkipLoading tags added to VSPackages.
/ResetAddin - Removes commands and command UI associated with the specified Add-in.
The last three show up when running devenv.exe /?. The first one seems to be undocumented/unsupported/the big hammer. From here:
Disclaimer: you will lose all your environment settings and customizations if you use this switch. It is for this reason that this switch is not officially supported and Microsoft does not advertise this switch to the public (you won't see this switch if you type devenv.exe /? in the command prompt). You should only use this switch as the last resort if you are experiencing an environment problem, and make sure you back up your environment settings by exporting them before using this switch.
How to hard reset Visual Studio instance
When developing extensions sometimes you just mess up, others someone else does. If you start getting errors loading even the most mundane extensions, these are the instructions to hard reset your instance.
Close Visual Studio (if you haven’t already).
Open the registry editor (regedit.exe)
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}_Config
Delete the %LOCALAPPDATA%\Microsoft\VisualStudio\{version} directory.
Enjoy your brand new Visual Studio instance.
Use {version}=10.0 for Visual Studio 2010
Use {version}=11.0 for Visual Studio 2012
Use {version}=12.0 for Visual Studio 2013
If on the other side you want to reset the experimental hive you can do the same to with the ‘{version}Exp’ ones.
Happy coding!

Executing the command: Devenv.exe /ResetSettings like :
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE>devenv.exe /ResetSettings , resolved my issue :D

Just repair Visual Studio itself from the control panel and that should do the trick!
1) Run Visual Studio Installer
2) Click More on your Installed version and select Repair
3) Restart
Worked on Visual Studio 2017 Community
I'm new to Visual Studio and couldn't find my answer anywhere else for hours over the internet..
I'm Using "Visual Studio Express 2012 for Windows" and everytime I create a new project with a blank page (XAML), the designer only shows me the frame of the page with its missing background.
And any control I drag to it, is invisible (I can only see the square border of the control I dragged but no texture..)
This is only happening during design time. On RunTime it actually shows up..
This is happening to me since I had the first fresh install. Just to be clear, I am NOT opening an existing previous project.. I have non. This is the first time I make a project in C# and I'm surprised I didn't find anything useful so far over internet search..
Also tried installing, uninstalling, repairing and changing to different versions...
The problem didn't show on Visual Studio 2012 Express for Desktop, but this product doesn't seem to be fit to my needs.. (I'm trying to also learn how to develop for Windows Store and other products)
The IDE doesn't show any errors or warnings..
Help would be much appreciated!
P.S - I'm running Windows 8.1
You can try Blend to open the project and render the xaml，if the problem appear too, maybe you should check out your graphics card or update driver.
try with this!
Check the following:
Tools -> Options
Expand Text Editor -> XAML -> Miscellaneous
Make sure that "Always open documents in full XAML view" is not checked
Or perhaps the default program for opening .xaml files has changed:
Right-click your .xaml file in Solution Explorer
Click Open With...
Select XAML UI Designer
Click Set as Default button
Click OK
If it's related to the video driver, maybe disabling hardware acceleration will help?
Or you could try Visual Studio Community Edition (http://www.visualstudio.com/, click on the Download button under "Free developer tools"
Did one of these suggestions work?
It's very hard in new visual studio copy and paste part of text because when control is clicked all types, methods, variables will be hilighted like links.
So i cannot quickly use control+c and control+v because when control is hold and you select with mouse part of method name visual studio will open method definition pane and then fragment from buffer will be pasted there!
This is very disturbing and annoying. Any way to turn this off?
I tracked this down to the Productivity Power Tools 2013 as well. Instead of uninstalling it like #Evengy suggests, if you use it for something else like Undo Close, you can just disable the option for that feature.
(Note: you'll need to restart Visual Studio for the changes to take effect.)
Was uninstalled productivity tools and it helps.
I've installed Visual Studio 2012 after reformatting my computer.
When I open a xaml file in a new empty wpf project, it opens it in a regular code editor and doesn't let me choose Design View (the option is just not there).
Right-clicking the xaml file and choosing "View Designer" opens a new code window instead of a new designer window. (yes, the same code window is actually opened twice)
Right-clicking the xaml file and choosing "Open With" shows that I'm missing the Xaml UI designer editor. (it doesn't show anywhere on the list)
I've tried running "devenv.exe /ResetSkipPkgs" and "devenv.exe /resetuserdata" and Repairing visual studio's installation all together (both by re-installing and the Repair button in the installation wizard).
Nothing seems to help.
Anyone familiar with the problem and knows how to fix?
Something else to try, I know a lot of folks disable the designer for performance reasons. This is done with a file extension association in visual studio. I'm wondering if the reverse may help you?
If you right click a XAML file in your solution and select Open with...
... You should see XAML UI designer as an option! select it and click 'Set as default'.
Hopefully that works for you.
I am just guessing, but my experience with VS2012 is, that sometimes it cannot access the registry, because it fails to set an owner for the newly created registry keys.
Without owner noone but the System can access those Keys.
I used resplendence Registrar Registry Editor Trial Version to Fix the broken Keys.
I would especially check
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0
and
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\XamlEditor
because you can find all the settings there.
In addition i experienced this error only on recently reformatted win 7 systems.
And all of them have ssd's, but i am not sure if it only occurs on systems where no "old" harddrive is. But i found some people on msdn who also experienced issues whith VS2012 and having only a ssd in the system.
Just recently, my Visual Studio 2010 stopped displaying IntelliSense suggestions automatically while I am typing. I can still press ctrl+space to get it to work, but it doesn't automatically show a list of suggestions like it used to. I have already tried disabling all my extensions, restarting VS and the computer, and I have checked all the appropriate settings (Options -> Text Editor -> C# -> IntelliSense) to make sure that it is set to offer suggestions after a character is typed.
Has anyone seen this behavior before? Does anyone have any other suggestions for how I can get IntelliSense to go back to the way things were before? If not, I might just have to do a fresh reinstall of VS...
In prose, in case you can't see the above image:
Open Tools > Options > Text Editor. If you're only having this issue with one language, find that language; if it's for everything, click "All Languages". Right at the top, there'll be a few options labeled "Auto list members", "Hide advanced members", and "Parameter information". Make sure all of those are enabled (though the second may be disabled; if so, ignore it).
I have found that at times even verifying the settings under Options --> Statement Completion (the answer above) doesn't work. In this case, saving and restarting Visual Studio will re-enable Intellisense.
Finally, this link has a list of other ways to troubleshoot Intellisense, broken down by language (for more specific errors).
http://msdn.microsoft.com/en-us/library/vstudio/ecfczya1(v=vs.100).aspx
I'll start off my noting that this hasn't happened since I upgraded my RAM. I was at 4GB and would often have multiple instances of VS open along with SSMS. I have since gone to 8GB and then 16GB.
Here's the steps I go through when I lose intellisense.
If only one file/window appears to be affected, close/reopen that file. If that doesn't work, try below.
In Visual Studio:
Click Tools->Options->Text Editor->All Languages->General
Uncheck "Auto list members"
Uncheck "Parameter information"
Check "Auto list members" (yes, the one you just unchecked)
Check "Parameter information" (again, the one you just unchecked)
Click OK
If this doesn't work, here's a few more steps to try:
Close all VS documents and reopen
If still not working, close/reopen solution
If still not working, restart VS.
For C++ projects:
MSDN has a few things to try: MSDN suggestions
The corrupt .ncb file seems most likely.
From MSDN:
Close the solution.
Delete the .ncb file.
Reopen the solution. (This creates a new .ncb file.)
Notes:
This issue does not appear to be specific to C# as C++ and VB users
report the same issue
Tested in VS 2013/2015
Steps to fix are:
Tools
Import and Export Settings
Reset all settings
Back up your config
Select your environment settings and finish
I also faced the same issue but in VS2013.
I did the below way to fix, It was worked fine.
Close all the opened Visual studio instance.
Then, go to "Developer command prompt" from visual studio tools,
Type it as devenv.exe /resetuserdata
Restart the machine, Open the Visual studio then It will ask you to choose the development settings from initial onwards, thereafter open any solution/project. You'll be amazed.
Hope, it might helps you :)
Deleted the .suo file in solution folder to solve the problem.
Sometimes i've found Intellisense to be slow. Hit the . and wait for a minute and see if it appears after a delay. If so, then I believe there may be a cache that can be deleted to get it to rescan.
I hit this today after the following sequence:
Added a new class to my project.
Closed Visual Studio, but accidentally selected No when it asked if I wanted to save changes.
Reopened Visual Studio, and found that it reopened the new file automatically but without my previous changes (as expected). However, IntelliSense was no longer working in the new file.
The problem was in addition to not saving changes to the new file, it didn't save changes to the project, so after reopening Visual Studio the file was not part of the project. The Show All Files command in Solution Explorer, or Add → Existing Item..., resolved the problem.
I had the file excluded from the project so i was not able to debug and have intellisense on that file.
Including the file back into the project solved my problem! :)
A new cause for this in the .net core era is having a project loaded for an unsupported .net core version. For instance if you loaded a project from GitHub that was set to use:
<PropertyGroup>
<TargetFramework>netcoreapp2.2</TargetFramework>
<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
</PropertyGroup>
But you only have 2.1 installed or find yourself using Visual Studio 2017 then the compiler wont be able to find the SDK code and thus provide intellisense.
The solution in that case might be to right click on your project and select Edit MyProject.csproj from the context menu and change the target framework as necessary:
<PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>
<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
</PropertyGroup>
This assumes whatever project you loaded can actually be run under a lesser target framework.
I simply closed all pages of visual studio and reopened ..it worked.
Deleting the .vs folder in the solution solved my issue. You have to exit from Visual Studio and then delete the .vs folder and start Visual Studio again.
Closed all my VS windows
Started the Visual Studio Installer and clicked 'Modify'.
Under 'Individual components' > 'Code Tools' > Deselected NuGet package manager and re-selected it.
After modifying and restarting VS, IntelliSense was working correctly again.
Found my answer on https://developercommunity.visualstudio.com/content/problem/130597/unity-intellisense-not-working-after-creating-new-1.html
[Tools -> Options -> Text Editor -> All Languages -> CodeLens]
Check if check box "Enable CodeLens" is checked
I have just come to about this problem while installing one of the extensions and its file was deleted by my anti virus so I just disabled my anti virus and reinstalled visual studio. Suggestions are working properly without any changes made after installation.
At the bottommost right look at the blue line where Ln, Col, Spaces, UTF, CRLF,..... here the language is specified.
Check that your language and the language specified there are the same.
In my case, it was Django Python while I was trying to use HTML.
This may be due to the solution configuration changed to Release Mode instead of debug. Right click on solution -> Properties -> Configuration Properties -> Set Configuration To Debug if it is in Release.
