When I build a C# program (this has been going on for several different solutions/projects I have been working on) in Visual Studio 2017, the new, updated code will build and run in debug mode (and run correctly).
However, the application that Visual Studio has been outputting when I build/debug them has been remaining with the original, first version of code that I saved. When I choose the options to rebuild, it will update the time stamp on the application and .pdb files, but the application will perform the way it did in earlier code versions, not the most recent code version that was running problem when I ran debug mode immediately after pressing Ctrl + F5.
These are C# Console Apps with the .NET Framework 4.6.1, if that makes any difference. I checked the output folder, and it is indeed the desired folder and the one I have been looking in... so why is the time stamp updating on the application (.exe file) that it outputs, but not the code itself? What am I missing?
When I run into strange things like this in Visual Studio, the first thing that usually works is to clean the project and rebuild. If that doesn't work, I'll close Visual Studio, re-launch, then clean and rebuild again. If that doesn't work, I would start looking into any extensions you have installed that might be getting in the way of your build process.
Further, you can look into logging the extensions activity to help troubleshoot if there are issue there. See the following article:
https://blogs.msdn.microsoft.com/visualstudio/2010/02/24/troubleshooting-extensions-with-the-activity-log/
You may have already tried this, but since it wasn't mentioned I thought I'd provide it for others in a similar situation.
Two possible reasons:
(1) Your project was not recompiled during debugging. Please enable Edit and Continue under TOOLS->Options->Debugging.
(2) Visual Studio has a concept of incremental build. If you have a solution with two or much more projects and if you change source code in only one of the two projects, the "Build" command will compile only the modified project. But the "Rebuild" command, on the other hand, it will recompile all projects in this solution.

I've got a C#/WPF application which was originally built in Visual Studio 2012. Eventually we upgraded to Visual Studio 2015 and that worked fine. Lately I've upgraded further to Visual Studio 2017 and now I'm having lots of problems. I've got the drop-down options set to "Debug," "Mixed Platforms," and my project name, and when I hit Start it does indeed start up my project. However any recent changes I make to the project don't get reflected.
At first I was wondering why a TouchUp event handler I had added wasn't seeming to be hit. Then after further experimentation, I changed one of the existing log messages slightly (we have a logger that logs to a local text file). However, it continues to log the old message. Another symptom of this is that none of my breakpoints get hit. When I add them it shows up as the standard red circle, but as soon as I press start they change to a white circle with a red perimeter, and the tool-tip hint says that it cannot hit the breakpoint because the source does not match what is running.
This is extremely frustrating as the debugger is one of those things that should just work. Has anyone else run into anything similar after upgrading to VS'17? Any advice?
So I found a workaround to my problem, but not a solution. When I deleted the files from the "bin" folder, it just stopped working altogether. So instead I manually built the project using MSBuild, in the C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin folder. The two commands I ran in succession were:
MSBuild.exe /target:Clean /p:Configuration=Debug /p:Platform="Any CPU" MySolution.sln
MSBuild.exe /target:Build /p:Configuration=Debug /p:Platform="Any CPU" MySolution.sln
In fact, I don't really need to do the "Clean" step every time, and this works. However it's really quite slow and I am genuinely surprised that VS apparently isn't doing this automatically, under the hood.
In short: I need to open an application originally built in Visual Studio 2008 (version 9) in Visual Studio 2013 without upgrading the project since the overall project architecture must remain the same for when I check it back into source control.
Details: I need to open a Visual Studio solution (.sln) inside Visual Studio 2013. The solution in question was originally developed in Visual Studio 2008, so when I try to open said solution in Visual Studio 2013, I am shown a prompt with the projects within the solution checkmarked, with the message:
These projects are either or supported or need project behavior impacting modifications to open in this version of Visual Studio. Projects no displayed either require no changes or will automatically be modified such that behavior is not impacted. Visual Studio will automatically make functional changes to the following projects in order to open them. You will not be able to open these projects in the version of Visual Studio in which they were originally created.*
My attempt at a fix was to just upgrade the solution and hope for the best. This is successful, but after building and attempting to run the main project, I see the following build error:
The type 'Microsoft.Web.Services3.WebServicesClientProtocol' is defined in an assembly that is not referenced. You must add a reference to assembly 'Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. *
I then tried both commenting out the references to this assembly and adding in the missing reference. Okay, so then I rebuilt the solution and attempted to run. Same error, but for a different assembly. Repeat fix, same error for different assembly. This pattern continues and continues, and at this point I realize this is unacceptable anyway, because when I make a change to this solution, I need to check it back into source control. When others open it, they may be opening it in VS2008, and therefore this “upgraded” version is inconsistent with the version the business uses. I need to open the solution originally build in VS2008 in VS 2013 (can't work around this, needs to be VS2013). If it helps, I'm using 64 bit Visual Studio 2013 Ultimate.
Any help or guidance will be greatly appreciated!
As several of the commenters have already helpfully pointed out, this is not possible. Round-tripping (i.e., opening and manipulating project files created by an older version of Visual Studio in a newer version of Visual Studio) was not supported until Visual Studio 11. The only way to open a Visual Studio 2008 project/solution in a later version of Visual Studio will be to convert it.
As far as interoperability with previous versions is concerned, you have two options:
Update the project locally (using the migration wizard provided), make any changes to the project file necessary to get it to build, and then edit the code files. Once you're satisfied with your edits, commit only the modified source files, not the project infrastructure files. Your fellow developers, stuck on VS 2008, won't notice any difference.
Update the project locally (using the migration wizard provided), make any changes to the project file necessary to get it to build, and then rename the project file (e.g., by appending a -vs2013 suffix to it). Commit this to your code repository. You will now have two project files in your root directory, one for each version of Visual Studio that your team works with. From here on, you just open the project file corresponding to the version of VS that you have installed.
I used approach #1 for a good part of last year, where I spent most of my time developing a C++ application in VS 2010 on a desktop machine, but also wanted to work on it on my notebook running VS 2013. Of course, in my case, it took a trivial amount of time for the automatic conversion to upgrade my project file after pulling from source control. I didn't have to do any tweaking thereafter to get the project to build. It sounds like your case is different, so option #2 might be a better choice.
I opened my WinRT (I'm using MVVMLight) project in Visual Studio 2013 this morning, and found out that all kind of types even system ones are not recognized saying Cannot resolve symbol 'bool' for example, note that the solution builds, executes and works all fine !
C# :
Even XAML :
I tried many things, closed and reopened the solution, cleared Resharper caches, I even restarted Visual Studio and the PC, but still the same problem, any solution to this problem ?
Update 1 : I tried to Suspend/Resume Resharper from Tools>Options and even delete files from AppData\Local\JetBrains\ReSharper\v8.0\SolutionCaches, and now Visual Studio causes errors too :
Update 2 : I uninstalled/re-installed visual studio, and I still have the same problems
If you have any Xamarin extensions for Visual Studio installed, it is a root of the problem. There are some compatibility problems.
As a possible workaround, you may try a workaround, mentioned in this ticket:
Select 'true' for 'Use msbuild to obtain project references' in
Project Properties (Click on project name in Solution Explorer | Hit
F4) for each project in the solution.
At least, it works for me.
If you can build the solution, but ReSharper marks your code in red - you can write the request here and you will likely get a help.
If you can't build your project then it is not ReSharper's problem. Then we need to find out why your build is broken.
It seems that your project to assembly references are broken.
To understand what's happening here with references during the build, go to Tools -> Options -> Projects and Solutions -> Build/Debug and set the verbosity to diagnostic. Then try to build your project and investigate the output windows in VS (or you can use MSBuild.exe from the command line instead). What you need to find in this large text block is "Resolve Assembly references" or "Expand SDK references" task. These tasks should obtain the valid paths to the assemblies your project depends on. Later on csc.exe should be executed with all these paths as parameters.
You can check whether the paths are correct, do they indicate to the existing binaries or not.
You can also create a new WinRT project template and check if it can build. If it cannot even for the clean project template then it is obviously a system problem, I suppose your platform sdk's are corrupted.
Hope this will help.
I wrote a WPF application in C# using VS 2010. The application will run fine in debug mode using Visual Studio, but when I go to run the .EXE from the bin\release folder, nothing happens. I do not get any error messages from windows and there are no errors or warnings in VS. I have tried to build, rebuild and clean the solution (in every possible order) with no luck. My solution contains 2 projects, both of which use .NET 4.0 framework, and I have .NET 4.0 installed on my PC. I have tried on both XP and Win7 and still nothing.
I also just noticed that the output from Debug when I run the application in debug mode says: "Cannot find or open the PDB file" after each .Dll it loads.
I am compiling to the Release folder every time, but i did try changing it to the debug folder and clean/rebuild just to see if that would make a difference, and it didnt, so I changed it back, tried it again, and still nothing.
Any Ideas?
Here are a couple of ideas that come to mind
If you are on a x64 machine, try changing the application from being AnyCPU to x86. This the mode that applications default to in debug mode and it's possible an issue running in x64 is causing a problem in release builds
Possible the Release binaries are out of date. Delete the binaries from the Release folder, rebuild and run the newly generated runs
Run the release build under the debugger in Visual Studio and see if it till crashes
I was experiencing the above issue too, however none of the other solutions worked for me.
My Application logs in Event Viewer listed event ids 1018 and 1022. This appeared to be bizarrely related to an ASP.NET 2.0 dll (bizarre; as this was a blank WPF project only). The logs contained messages like this:
Windows cannot open the 64-bit extensible counter DLL
ASP.NET_64_2.0.50727 in a 32-bit environment
In the end it turned out to be resolved when I disabled my anti-virus. I had read that this resolution worked for someone with McAfee; and it also worked for my environment, which has Avast.
I assume you tried on a machine that doesn't have visual studio installed, and also none of the components you are using for development.
You have only one option: start the application with a debugger on the machine that causes problems and check for exceptions there. (use WinDBG for example - it's light and easy).
This looks like a problem with missing dependencies, but might be something else also.
The Debugging Labs should give you enough information on how to use windbg to find your problem:
.NET Debugging labs
Also use this:
WinDBG Cheat Sheet
(JaredPar) answer looks right (x64), but if not try right clicking on the EXE and running in admin mode for win 7.
I had a very similar issue.
Check out this setting on your App Pool entry:
Go to Advanced Settings.
Change 'Enable 32-bit Applications' to 'TRUE'.
This worked for me!
I'm going to go with a wild guess that:
Either you have some odd corruption in your .NET Framework installation
There is some debug/release-specific code using #if DEBUG or the such that is substantially different to cause issues.
You have not compiled recently into Release yet (Try changing it to Release before compiling your latest code and make sure you get no errors).
Those are the only things I can think of off the top of my head.
I had run into a similar issue, I was missing a custom folder in the release mode I was referencing in the constructor. Adding the folder to the release fixed the problem.
Visual studio team system 2008 keeps crashing on me. Sometimes it just freezes, or certain parts of the UI get messed up or a weird popup box saying something about unable to load parameters or saying something else about memory or any other number of things.
it usually happens when I do a "complex" task like go into debug mode or do a search across of whole solution or run a unit tests or something like that.
I rebooted my machine countless time, reinstalled it VS, changed my virtual memory settings, flush my page file on every reboot and anything else i could think of.
It seems like VS runs out memory or something.
I have a powerfully machine with lots of RAM so that's not the issue
any suggestions?
You can always try some standard Visual Studio troubleshooting steps:
Clean the solution
Delete / rename all files in your solution created by VS, i.e. all .ncb, .suo, .user files
Launch Visual Studio with all add-ins disabled: devenv.exe /SafeMode
Reset All Settings: Tools -> Import / Export Settings -> Reset All Settings
Delete HKCU:\Software\Micosoft\VisualStudio\9.0 and then restart Visual Studio
Repair the Visual Studio installation through Add/Remove Programs
You might also check whether there is a hotfix available addressing your issue (e.g. KB960075 sounds like a good candidate for you), or whether you find your problem already reported on the Connect website.
The first step is to uninstall all 3rd party add-ins on Visual Studio. In particular if you have multiple add-ins as they can interfere with each other in unexpected ways and cause crashes. After uninstalling repeat your scenarios and see if this fixes the issue.
If not then it's best to consult the application log and find out why Visual Studio is crashing. The log will contain at least the error code of the crash which can searched on google or reposted here for us to take a look at.
Assuming this occurs with VS up to date with all service packs installed, you might try some of these suggestions. If you haven't tried with service packs, do that first.
What version of Windows are you using? If it is Windows 7, try launching Visual Studio with a compatibility mode and see if that resolves the issue. To do this, make a copy of the normal launch shortcut and go into the Properties dialog and set it to run as Windows Vista.
If this doesn't fix it, then you might also consider:
Checking your PATH environment for any weird settings which might be confusing it, e.g. paths pointing to other SDKs
Any 3rd party VS extensions such as source control, refactoring plugins, wizards etc.
Old versions of .NET or SQL server
Also test if the issue occurs for every kind of project or just certain kinds, e.g. does it happen for all projects? Does it happen in C++, C#, VB.NET projects etc.
You can also attach a debugger to Visual Studio, to see what it's doing. Sometimes a particular .sln will trigger bad behavior or more likely, some third-party add-on.
If you believe that you've gotten VS into a wired state, you can try the following command line switches
devenv.exe /ResetSettings (This will reset the visual studio settings to the defaults)
If that doesn't help, as a last resort, you can try
devenv.exe /ResetUserData
