title: Change file full path in a C# project in Visual studio 2012
body: <p>In your opinion , it would be possible to change a file full path in a C# project, In Visual Studio 2012?? I ask this because in visualization, the properties box for a project file that contains full path appears as disable ( gray).
  I would use the same file in different project, under the same solution, without duplicate file code .cs.</p>
