Not able to run the Windows Workflow Foundation sample HiringRequest

I am currently exploring the possibilities of WF. Now i downloaded some sample from here. I wanted to take a look at the hiring request sample applications which is also showed in one of the webcasts from enpoint.tv.

When I start op the project and want to see how the HiringRequestProc开发者_开发知识库ess.xaml looks like I get errors.

It's says that the x:string, x:TypeArguments etc cannot be resolved.

Anyone has any idea's how I can get the sample running? I'm running vs2010 ultimate as an administrator.

I got it working now. I extracted all files to the root of my drive and now it seems to work.
