Hard time getting CopyFileEx to work about cswin32 HOT 3 CLOSED

Hi @wldevries. Thank you so much for giving this a try and for providing great feedback. I'm sorry your first experience wasn't better.

You've made several good points here. I will look more into them next week to see where we can improve. My goal is to provide you with a sample of how to make it work, and any fixes we may need to make here in order to make that happen.

Some of the issues you raised with the generator itself have been fixed. You can try them out in the daily build (see readme). Also, please try using VS from the Preview channel, as many fixes have been made to the IDE integration of Source Generators in VS 2019 Update 9.

This seems to work:

    public unsafe void CopyFileEx(string src, string dest)
    {
        PInvoke.CopyFileEx(src, dest, CopyCallback, lpData: null, pbCancel: null, dwCopyFlags: 0);

        unsafe uint CopyCallback(long totalFileSize, long totalBytesTransferred, long streamSize, long streamBytesTransferred, uint dwStreamNumber, uint dwCallbackReason, SafeHandle hSourceFile, SafeHandle hDestinationFile, void* lpData)
        {
            throw new NotImplementedException();
        }
    }

I'm closing the issue to help with tracking, but comment here and we can reopen if necessary.
