How can I add C# language support to Visual Studio 2010 shell?

Greetings,

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.

My problem is that C# (.cs) files open in the shell as if they're plain text files; there's no s开发者_运维百科yntax colouring nor value evaluation on mouse hover over properties or values.

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".

VB.Net language support is working well in the shell. I get all the features I have in Visual Studio Express.

Is there a way to get C# language support in the shell?

The Express editions of Visual Studio are a little different than the other SKUs (Professional, Ultimate, etc.) in that there are separate products for the various .NET languages.

My guess is that you have Web Developer Express installed, but in order to open C# code files with the full support of the editor (syntax highlighting, debugging, etc.) you need to download and install Visual C# Express. Multiple versions of Visual Studio Express work side-by-side just fine.
