问题
I am pretty new in C# development and I have the following problem.
When I try to build the application on which I am working I obtain the followings errors message:
Error 2 Source file 'Log\LogUserManager.cs' could not be found C:\Develop\MyFramework4.0\MyManagerCSharp\CSC MyManagerCSharp
Error 8 Source file 'AntiPhishing.cs' could not be found C:\Develop\EarlyWarning\public\Implementazione\Ver2\UnitTestProject\CSC UnitTestProject
It seeams to me that these errors appeared after an SVN update.
Why? What exactly means? If I click on the error line it don't take me to the code line where the error appear. What is the CSC file? How can try to fix this issue?
Tnx

These are not errors in the code but errors in the references of your project. Check that the references are indeed located where they point.
It is possible that when doing your SVN update, some source files have been moved but you didn't update your .csproj containing the references to these files.

This question occurred a long time ago, but for others that view this, make sure that the c# files are on your hard drive. Sometimes the Solution Explorer shows that they are there, but they aren't.

This can also happen if you renamed your startup class, but didn't update the startup object in your project settings.

CSC is the references/dependencies. Since DLLs are technically compiled already there's not much you can do to fix them, that is, if they were broken.
One possible reason for your issue is that your references are not actually where the IDE expects them to be. AKA, the dependencies can't actually be found. This might be the case, even if the IDE's file browser(s) say otherwise.
It's also possible that you had the error at some point in YOUR code, then fixed it, and then VS decided to act retarded and tell you something is wrong with your "CSC" files. Trust me, that just happened to me, and it confused me so bad I spent over half an hour trying to fix a bug that didn't exist.
Don't worry, if that's the case, just restart VS and re-open your project, then it should work just fine. If it doesn't fix the issue then try checking that all your dependencies are *actually there*.

I got this error after deleting a controller. I had already removed all references, but Visual Studio was still looking for the file.
After running the clean command, unloading, and reloading the project, VS showed the reference to the missing file in the solution explorer. I right-click > deleted the file (again).
The project ran fine after that.
