VS 2010 .NET 4.0

First of all, JustCode is a very nice tool that helps me to make beter software faster.

I converted my solution to VS 2010 and .NET 4.0 today.
JustCode now gives me a lot of errors. Most of them have to do with the LinqToSQL classes in the solution.
I think I have all these error because of the error Unknown type or namespace 'Linq' of 'System'.

Apperently JustCode doesn't understand the System.Linq namespace in .NET 4.0?
All errors JustCode returns are in the Web application and I think I get these errors because System.Core isn't referenced in the Web application project. But VS 2010 doesn't allow me to add it to the References because it is automatically referenced by the build system.

What can I do so JustCode understands the System.Linq namesapce from System.Core.dll?

After updating Telerik extensions using the Extension Manager of VS 2010 the problem went away.

Thanks for posting your solution! I had the same problem, and updating the Telerik WebUI VSExtensions solved the problem for me too.

Telerik: why does this happen?
