Resolves #2870

Before the change?

When trying to delete a file an exception is raised stating System.ArgumentException: The value cannot be null or empty. (Parameter 'mediaType'). And the file is not deleted

After the change?

No exception is raised and the file is deleted.

Hmm...I'm uncomfortable making this change with such a broad impact. Can it be scoped down to the one request necessary?

@kfcampbell , I agree that this can be dangerous. I will look at a way to narrow this fix to the delete request and make it available to other kind of request if the issue appears on other. Thanks for your comment

@b3b00 if you get the chance post what your use (code) of the SDK here looks like - specifically I am trying to find out which resource client you're using so that we can help you craft a solution. We have some mechanisms in place to support adding headers to the request - adding where you have will definitely have some side effects for all of the other implementations that use SendData.

Hello @nickfloyd, my code :

     public override async Task DeleteNote(string noteName)
        {
            if (gitHubClient != null)
            {
                var content = await NoteExists(noteName);
                if (content.exists)
                {
                    // this is were the exception happens
                    var deleteRequest =
                        new DeleteFileRequest($"DendrOnline : delete note {noteName}", content.content.Sha);
                    await gitHubClient.Repository.Content.DeleteFile(RepositoryId,$"notes/{noteName}.md" , deleteRequest);
                }
            }
        }
