title: Find location of standard .NET assemblies?
body: <p>For a little C# compiler, I need to find the paths of the standard .NET assemblies like System.dll, System.Xml.dll and pretty much all the assmeblies listed under the ".NET" tab in the "Add Reference" window in Visual Studio (2010).<br>
  I would use the absolute paths but I have a feeling that this can break in exceptional cases.</p>
