I have Visual Studio 2008 Pro and before I got SP1 for .NET 3.5 and VS2K8, a workflow project would work fine. Then I installed the SP1, and when I load my solution (consisting of over 60 projects), a Windows Workflow project gives the following error:
Cannot load project type (as a dialog box)
How can I fix this? My solution is in .NET 3.5
Thanks
