title: How can I add C# language support to Visual Studio 2010 shell?
body: <p>Greetings,</p>
  
  <p>I'm using Visual Web Developer Express 2010 to do some development; I have also the Visual Studio 2010 Shell installed, which I use to debug server and client code, using the Debug>Attach to process command.</p>
  
  <p>My problem is that C# (.cs) files open in the shell as if they're plain text files; there's no syntax colouring nor value evaluation on mouse hover over properties or values.</p>
  
  <p>Sometimes when I open ASP.Net pages in the shell I get an error message saying "The Visual Studio language support for C# has not been installed. Code-editing IntelliSense will not be available. Markup IntelliSense for server controls may not work".</p>
  
  <p>VB.Net language support is working well in the shell. I get all the features I have in Visual Studio Express.</p>
  
  <p>Is there a way to get C# language support in the shell?</p>
