title: Edit .NET assembly and recompile
body: <p>I'm in a really bad situation. I lost my source code and my customer needs to change a little bit in the application. Think of edit an assembly for an example: Test.dll then add a code line and finally recompile it</p>
  
  <p>So my question is:
  - Is it possible to do that?
  - If it's possible, what is the good tool to edit an assembly and then recompile it?</p>
