SYMPTOMS

You use the workflow designer to open a large or complex Windows workflow solution in the Microsoft Visual Studio 2008 Service Pack 1 (SP1) IDE. You try to open one of the following dialog boxes:
  • The Bind to an Activity's Property dialog box
  • The Browse and Select a .NET Type dialog box
  • The Rule Set Editor dialog box
  • The Select Rule Set dialog box
In this situation, the workflow designer takes a long time to open the dialog box.

Note The performance issue occurs when your computer has Microsoft Enterprise Library installed together with the Configuration Editor for Visual Studio feature.
