Why does C# encounter this error as to the CSC file?

Question

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

Answer 1

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.

Answer 2

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.

Answer 3

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

Answer 4

After trying almost everything this is what I found:

The root cause of the problem is garbage in the .csproj or Project file. In order to find the problem do the following:

1. Right click and Unload the project file
2. Right click and Edit the project file
3. Search on the text for the reference that is giving you errors, probably will be in a
4. Delete it or fix the entry.
5. Right click and Reload Project.

For posterity, it is also worth noting that if you enabled the XML documentation file in Visual Studio (project properties > Build > Output), set an absolute path to it, and then push it to your code repository of choice, anyone pulling your code and not verifying this will encounter a particularly unspecified error in the CSC file. Should this be the case, even doing a clean build will produce the error in all individuals who pulled your code (assuming the path does not exist on their system).

In this scenario, the path should be removed from this and only the filename should be left.

I do not know if other compilers will encounter this issue, but it is worth looking into as well.

Answer 6

Cleaning the solution helped resolve some of my dll not found errors, in the CSC file. Not sure your specific error but cleaning/rebuilding might be helpful to try if you haven't already.
