“ GenerateResource”任务意外失败

Question

Today I installed the free trial of ReSharper to clean up an application in Visual Studio 2015.

I have always built this application by using alt + b + h which is the same as choosing Build -> Publish AppName , and this is usually pretty reliable when it comes to producing an EXE, ready to use.

However, after doing some cleaning up (mainly LINQ queries, renames and deleting no-longer-used methods/fields), I see this error when try to publish:

Error       The "GenerateResource" task failed unexpectedly.
System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+.

And no output is generated.

I have restarted VS with no effect, and have also noticed that I was able to build the project by opening Developer Command Prompt for VS2015 and running "msbuild C:/path/to/solution.sln" .

This did create an EXE in the right place, but whenever I try opening it I get

Appname has stopped working - Windows is collecting more information about the problem. This might take several minutes...

Does anyone have any tips as to how I can get to the bottom of this?

Extra Details

After looking at the Form Designer in VS, I can see that one of my images is corrupted (the colours have changed and lots of lines and marks which weren't there before)

Removing a couple of images I found which looked corrupted, the project built, but still crashes on execution

Answer 1

After running in debug mode I noticed it was throwing an exception in the Resource Designer when PageControl was being called (even though it had already been declared).

This seems to have happened after changing this:

Class PageControl1
{
    // Code goes here
}

To this:

namespace AppName
{
    Class PageControl1
    {
        // Code goes here
    }
}

Which I don't quite understand - to me it makes sense that a class being used by the application should live in the same namespace as all the other classes used in that application. I would very much appreciate any insight into this.

After changing PageControl1 back to how it looked originally, I removed the 2 corrupted images (which appear to have become corrupt straight after making the above namespace change, and replaced them with some new images, and this solved my problem.
