My company develops a quite extensive .net application, consisting of multiple projects, all hosted on a Team Foundation Server. I'm currently working on a companion app (Windows Phone 8.1, c# and XAML), which is quite small, has it's own solution but also is part of the VCS. When I try to check in, Visual Studio 2015 gives me a policy warning:
The Code Analysis settings for one or more projects are not compatible with Code Analysis policy.
On Double-clicking that message, it lists several rules which it claims are not present in the project settings (Including a dubious "rule 0"). The thing is, in the Project Settings I've set up the Code Analysis to use the same Rule Set the rest of the application is using. And this rule set, when I open it, does actually contain the rules that VS claims are not present in the settings (except for that rule 0). I'm stuck here, any suggestions at what could be going wrong or what else I could try would be greatly appreciated.
(And yes, I know I can override the warning, but I'd actually like to get the Code Analysis working.)
EDIT: I've checked the Release and Debug configurations. We even have separate rule sets for the two configurations, but they both seem to be set up correctly.
One thing that can help with weird policy errors when everything is configured ok with regards to Debug / Release rulesets, and where a rebuild doesn't clear it is to delete the suo file. (This is the Solution User Options file).
Steps:
Close Studio
Delete the SUO (for Visual Studio 2015, this is in the .vs folder)
Reopen Studio
It turned out I had to actually build the release configuration and check in with that build active.
It went back to not working again after the other answer temporarily worked, and going over this in detail with a colleague, he finally pointed that out to me, that usually the check-in should happen with the release build, not the debug one.
Visual Studio was incredibly unhelpful with its error messages about this, and I'm still not sure why I was temporarily able to check in with the debug build, but it's now up and running fine.

We've created a number of C# code snippets. If I import them directly using the Code Snippets Manager they work perfectly as intended.
Since we are going to have people rolling into our project at different moments in time we want to ease the on-boarding process so we want to include these snippets into a VSIX project. For that purpose I followed this process to the letter.
Now there are several issues going on:
1. When I run the VSIX in debug mode I get the experimental instance of visual studio but the scripts' folder is not in the manager and the package does not seem to be installed when I look in the "Extensions and updates".
If I close VS and run the VSIX installer, after re-opening VS I can see the package installed in "Extensions and updates", I can see the custom scripts' folder in the scripts manager and all the scripts are there but, when I open a code file and try to use them they are just not available, the short cuts are not recognized and the scripts are not available in the insert script context menu.
We have tried both approaches in three different environments and the behavior is the same.
We are using Visual Studio 2017 with .Net Framework 4.7.1
I have tripled checked all the settings, made sure there aren't any typos, all the files that need to be added are there in the right place so I do not know what else to check or try.
I am sorry that I do not include any code but there are some things that are deemed confidential but I tried doing it with the Hello World example and I got the same result.
Thank you for any help you can provide.
So as it turned out, there were multiple causes for this behavior.
Environment 1: With the brand new instance of Visual Studio 2017 there was a folder in the Snippets Manager named %LCID%. Within this folder there were two snippets specifically for MVC 4 applications. We do not know why but either these snippets or the folder was preventing our custom ones to be detected, once we removed this folder everything started working as expected.
Environment 2: This environment did not have the %LCID% folder but had ReSharper installed on it and it was configured to use the IntelliJ keyboard schema. As soon as we changed it to use the Visual Studio one then the snippets became available.
Environment 3: In this one the %LCID% folder was not present and the ReSharper keyboard configuration was set to Visual Studio. We disabled ReSharper and the snippets would still not be available. We basically were never able to figure out why the snippets were not available so we ended up going to the file system, cutting them from the custom folder and pasting them under the "My Snippets" default one and they became available.
Hopefully this information will be useful for someone or, even better, somebody might be able to explain why situations one and three would cause the snippets to not be available.
I am in charge of testing VS 2015 and how it works with our current applications for my employer. We currently use VS 2013 for everything we have, so I know there are no issues there. The problem I am having is that it appears the vshost.exe isn't terminating correctly or something. I have not narrowed down the exact issue but so far that is what I believe.
Here is how I get my error:
Run my app in debug
Open a few windows
Hit the "Stop Debug" button (the little red square)
Clean Solution
Rebuild Solution
After my rebuild I get the following errors in the EXE:
Error Could not copy "obj\Debug\APP.exe" to "..\..\bin\APP.exe". Exceeded retry count of 10. Failed.
Error Unable to copy file "obj\Debug\APP.exe" to "..\..\bin\CRM.exe". The process cannot access the file '..\..\bin\APP.exe' because it is being used by another process.
If I open the Task Manager and manually end the vshost.exe process I can successfully rebuild again, no issues. If I take the same steps, however, I am no longer able to build.
I tested these steps in 2013 and did not have an issue.
Also note that disabling the "Enable the Visual Studio hosting process" does alleviate the issue, however I do not want to disable this option.
Has anyone else had this issue? I know we are still early in release. Any suggestions/solutions to try? Is it possible there is something wrong in our code (which I highly doubt since I would then get the error in 2013, most likely).
Thanks for any help I receive!
EDIT: This is a WPF application written in .Net 4.0 using C#. Also, I have verified that the issue also occurs if I exit the application normally (IE I open a window then close it with the shutdown mode on LastWindowClosed)
SECOND EDIT: This is a new issue that presented itself in Visual Studio 2015 with the addition of the new live diagnostic tools.
I have found that if I have the "Enable Diagnostic Tools while debugging" option enabled in the debug settings I get this error. If I disable this option, the error goes away. I am not sure if this is a bug in Visual Studio but I would assume so, unless I need to do something else to shut them down properly. If anyone has comments or concerns, feel free to leave a note.
Probably late for the original question (and I see that he had a workaround), but as per MSDN, VSHOST.exe is only an enabler for improving Debug performance or facilitates scenarios such as partial trust debugging. If you do not need that support or can bear the cost of starting a process and attaching the debugger on each debug session, go ahead and disable the hosting process from project designer -> Debug -> Clear the box "Enable Visual Studio hosting process"
My breakpoints aren't getting hit in Xamarin Studio. I'm not sure if this has to do with my code, or not, but I feel as though it doesn't because I've tried over and over putting breakpoints all over my project (in places where I know they should definitely be hit, and in places that the code works perfectly and is completely unrelated to the feature I'm currently testing) and none of them are getting acknowledged when I debug. I don't have the breakpoints disabled, and I don't have them added in the wrong place. The breakpoints should work normally, and they're not. I'll also add that I'm not allowed to pause my application during the debugging process. I suppose you could say the debugger in my Xamarin Studio isn't working and I have no idea why. I believe I've determined it's unrelated to the code, but I can't be sure about that still. Please help. Thank you.
It is the most popular question about: "breakpoints are not being hit in xamarin" in google, so after whole day of trial and error I am gonna post here a solution for this problem for xamarin versions > 4.0.0.xxx. Yes, sadly this is simple.
SOLUTION
(This solution is for android app in visual studio, but should work in xamarin studio as well)
Remove all symbols from the path to your "Debug" Folder (usually: [path to your .sln file] \ [your solution name] \bin\Debug):
So if you got for example:
G:\My Files\Programming\C# (+ JS)\Test1\Examples\LINQ to Objects\AndroidDemo\AndroidDemo\bin\Debug
Change it to:
G:\My Files\Programming\CSharp\Test1\Examples\LINQ to Objects\AndroidDemo\AndroidDemo\bin\Debug
For me "(" and ")" symbols were causing the trouble (Who is using such symbols in the path anyway right?)
To verify that this is working, open your debug folder, in VIsual Studio Select "Clean Solution", "Recompile Solution", "Deploy".
"Deploy" action should generate *.mdb files which include your debugging data. If they are present, you should now be able to stop at breakpoints.
Now you can simply hit F5 like usual whenever you need to debug something.
I'm not sure if someone is still following this thread, but this workaround worked for me.
The problem sometimes has to do with the mono 5.
So the resolution is to use older version of mono:
Set "Project > Active Runtime" to "Mono 4.8.0 (8f6d0f6) (/Library/Frameworks/Mono.framework/Versions/4.8.0)".
for Mac users, change it in "Preferences" -> ".NET Runtimes"
Then Rebuild the Android app project.
Deleting the BIN folders and any *.SUO file is a favorite fix for this issue.
Can also try deleting any *.csproj.user
In worst case, reset VS Settings by launching (Run) with "Devenv.exe /ResetSettings"
Make sure you have your build configuration set to Debug.
Make sure your project's build settings are set to allow emitting DEBUG symbols for your Debug configuration.
Clean and Rebuild your solution/project.
Close and restart Xamarin Studio.
Reboot your computer.
Sometimes the build configurations for your solution can get complicated, and it's easy to miss something when building a complex build configuration. Make sure everything is setup properly in there.
I encountered this yesterday, using VS 2013 and Xamarin plugin. "All of a sudden" breakpoints in a PCL project were not active, even though breakpoints in an Android project still were. Everything had been working perfectly for weeks, and I had applied no updates. Looking at the VS Debug | Windows | Modules view, I could see that symbols were not loaded for the PCL assembly, and nothing I tried would force them to load, even though they were present in the folder with the running assemblies.
Then I remembered that the last thing I had done the prior day was not related to code, but was a bit of refactoring of csproj files to support a parameterized Jenkins build. I had placed an OutputPath definition in the first "shared" PropertyGroup, and removed it from all of the Configuration/Platform-specific PropertyGroups, e.g.:
<OutputPath>bin\$(Configuration)\</OutputPath>
I deleted this "common" OutputPath and put it back into each specific PropertyGroup (offending my DRY sensibilities, mind you), and things started working again.
This is probably not going to bite very many people, but it wasted a couple of my hours, so hopefully it spares someone else. The Xamarin build probably does some of its MSBuild/xbuild spelunking with strong expectations, so if you've modified your csproj files for a build process, this might be a possible culprit.
I add this answer because this is the only one that worked for me, in Project Properties > Build I wrongly checked Optimize Code.
Unchecking this box solved the issue.
I switched from stable to alpha Channel v.3.11.785 (Alpha). all breakpoints are now hit.
I faced this problem in Xamarin Forms app using Visual Studio for Mac. In my case, it was happened because of debugger. Visual studio was continuously showing "Waiting for the debugger to connect to the iOS simulator..." while running in an iOS simulator. I did reset the simulator (Hardware => Erase All Content and Settings) and cleaned up the solution. Then I could do the debugging with breakpoints. Hope this helps someone.
I had the same problem.
THE CAUSE (IMO):
In my case the problem is caused by Xamarin Studio (but with VS2013 is the same) build/rebuild process.
More in details, the *.mdb files are not correctly regenerated and therefore the debugger does not work properly.
You can check by doing a solution clean and going to bin/debug folder: if you still see *.mdf files then that's the problem in your case too!
SOLUTION
The only solution that works well is to manually delete all *.mdb files in bin/debug from all projects in your solution (so Android project and all PCL projects) and then do a Rebuild.
Let me know if this helps!
For me "(" and ")" symbols were also causing the trouble, I was searching for weeks for this problem. Remove the "(" and ")" in the full path, do a clean build and de breakpoints are hit again.
In my case, xamarin was not hitting any breakpoint. Red color rings were shown instead of filled red circles, because there were some syntax errors not able to be pointed out by xamarin, since I think solution build was not up to date, even I was able to run the app surprisingly. So I cleaned and build the solution, and it pointed out errors and relevant warnings after that. I fixed those, and ran the project. I was able to debug successfully after that!
If once the project launches on the device VS reverts to the standard editing mode (no debug options enabled in the menu) i.e. the debugger is not attached; check Project Properties > Android Options > Enable developer instrumentation is checked. For me the setting was disabled (most likely checked into source control after a release).
Use "Visual Studio for Mac" (Preview at the moment but works) instead of "Xamarin Studio". This fixed the problem for me. Breakpoints are working even in my PCL projects! Another thing... I had to change "project.json" (JSON format) to "packages.config" (XML format) when changing from "Xamarin Studio" to "Visual Studio for Mac".
I am having great problems running the application in the debugger from Visual Studio 2008.
When I'm using vshost.exe, it says:
And when vshost.exe is turned of, it simply states:
Interesting thing about it is that when i do use vshost, debugger is actually started and breakpoint is hit on the first line of the Main().
I tried:
rebuilding the project(s)
removing .ncb, .suo, .user for the projects
repairing Visual Studio 2008
changing the build architecture for the project
... no help there...
Any experience in (trouble)shooting that?
More info: some projects DO work, and one that I have to work on, does not.
I have some ideas such as:
trying to create NEW project, add thing by thing to it and see at what point it will start to miss behave
work it other way around, delete project by item by item to see when it will (if it will) be working OK again.
EDIT (for google, as I see that there are many similar questions on the web):
Errors:
Error while trying to run project: Unable to start debugging.
and
Error while trying to run project: Unable to start program '....\PlayKontrol.exe'
Try upgrading your Visual Studio to Service pack 1, if you haven't already.
Did you restarted your computer? You never know how windows will react to that :).
Also be sure there aren't any keys stuck, like the ctrl or windows key.
Note that the key does not have to be visually stuck, it can be stuck for visual studio and not for the explorer.
The most common source of sudden problems like this is corruption of one of the data files that vs uses to cache information between builds.
You've tried a clean build, but this won't delete everything. A real clean build is: quit vs, delete bin, obj, debug, release folders, delete all generated files in the root - primarily ncb. Do the same for any locally built libraries that you're project references.
The easiest way to do this is if you have the code in source control, as you can rename away your entire code folder and then force a get of all the source.
You often need to do all of these things in one hit to clear the problem.
Less frequently, a reinstall of vs will sort things out (although this sounds unlikely in your case if it is only one project that breaks)
Also think carefully about anything you might have installed just prior to it failing... And remember that some install effects may not occur until the next reboot so it could be days ago. A particular cause of this are automatic windows updates and trial versions of things like the vs 11 beta.
You might try running the application from outside of VS, but have a line of code that looks like this: Debugger.Launch(); where you want your first breakpoint.
I'm using TortiseSVN for my subversion client on a Windows Server 2008 box and I've got a folder with code checked out into it.
When I go to open the solution file that's under source control Visual Studio 2008 starts and before it can even finish loading the solution from what I can tell Visual Studio crashes. I'm trying to open a solution that has VB code in it. It gives no error messages or warnings. It's just gone.
I have checked the files and they all seem fine. The solution file seems fine when I look at it with a text editor.
This is also Visual Studio 2008 SP1 and I've got all the latest .NET service packs installed.
Has anyone else seen this before and know how to fix it?
Edit: I just did an SVN export to a new directory and it still crashes in the exported directory where there is no longer any SVN attached to it.
Additionally, it crashes EVERY time I try to open the project that came from SVN.
You should be looking at the solution file with an xml editor, at least then you will get some help for subtile flaw's in the formatting or something like that.
You can also submit feedback to Microsoft on the VIsual Studio Connect site, if the bug turns out to be real.
Some commonsense things todo however would be, goto your visual studio command prompt, start off with "devenv /ResetSettings", that often helps isolate any weirdo add-on or something lke that.
Also, try to build clean with msbuild or vcbuild, then build fully with either one (i.e. if vcbuild can not build your solution, use msbuild). That can help by laying out the symbols and such and maybe clear out some corrupted file or something.
You also may have .suo files from your subversion, those are binary files that do contain some settings, it's common for people to accidentially check them in, but they are usually better off being kept on a per-developer basis (not in the source tree). The /resetsettings will likely clear these out also, but you may want to make sure.
You can also double check the path's to all of the assemblies referenced, that your not going from a 32/64 bit host, and the CLR DLL's are in different path's now etc...
One last thing, if your really stuck, you can get a stack trace and debug the crash a bit ;), see where the fault is occuring and search that module online, your'll often find that somebody may have a specific solution.
Oh yeah, also, hooker's can be trickey. Don't trust them for a minute. Make sure you set tsvn's "only load in windows exlporer" option and configure it specifically for what folders on your system have local-svn working directories, this will greatly reduce the working set for their shell extension. On most any system, over time, one program or another (apple irw.exe or adobe pdf-preloader.exe sort's of ad-ware) will try to work it's way into your shell. You should try to make sure your dev box is rather clean from anything hook's, simular to what VladV was saying...
I had a similar problem and I fixed it and afterwards I wasn't quite sure how I managed it.
It basically involved going to the tools/options menu and setting the source control plugin to none. However, I obviously had to have had the solution open in Visual Studio if doing this was to fix the solution, but yet I thought the problem was I could not open the solution.
The only possible scenario would be if I was able to open the solution, but not open any of the projects inside it, hence able to change the source control settings immediately after opening the solution.
Does that make sense?
Try opening your solution and projects files in a text editor, and looking for anything strange.
I once heard of a similar problem: a solution contained SVN bindings created by AnkhSVN, but Visual Studio had no AnkhSVN installed, and failed to open the solution without giving any meaningful error information.
