Integrate DSL to Isolated Shell

Hi,

I also ask this  question here:
http://social.msdn.microsoft.com/Forums/en-US/dslvsarchx/thread/fe47d252-606c-495d-8703-7ba6d78fbe39/

But the told me, it could be more a Isolated Shell problem. So I try my luck in the VS Extensibility forum. :-)

I want to integrate my DSL into an isolated shell. Therefor I used this walkthrough:
http://msdn.microsoft.com/en-us/library/cc138363.aspx

But now, I'm stuck at point 4. The shell itself is completely empty. No templates and so on.

If I create a file and name the extension like my extension for the DSL, nothing happens. If I reopen the file, the normal texteditor is called.

I don't exactly know what "Shell Dependencies" is at point 2. I only have references in Visual Studio 2010. But even if I set the references under "framework and references", nothing happens.

Thank you.
