title: Visual Studio unknown build error. The fully qualified name must be less than 260 characters
body: <p>I'm having trouble while building my WPF solution. Everytime I try to build it, I get this error message: </p>
  
  <blockquote>
    <p>Unknown build error, 'The specified path, file name, or both are too
    long. The fully qualified file name must be less than 260 characters,
    and the directory name must be less than 248 characters.'</p>
  </blockquote>
  
  <p>Someone can help me? I've already verified all the fields and their extension paths are ok. Can this be a problem with the TortoiseSVN or something like this? I recently added a folder to my solution, can be something with this?</p>
