SYMPTOMS

When you try to open a form in Design view in Microsoft Visual Studio .NET 2003, the form takes a long time to load, and you receive the following error message:

'An error occurred while loading the document. Fix the error, and then try loading the document again. The error message follows:Item has already been added. Key in dictionary: "{Form1}" Key being added: "{Form1}'.

This problem occurs when the form contains lots of controls or member variables.

WORKAROUND

To work around this problem, reduce the number of member variables in the form. To do this, try to encapsulate the member variables into an inner code structure.
