Occasionally I get an error message like this after adding a control. Only thing I can do is close the project and try again. Any ideas?

The designer loader did not provide a root component but has not indicated why.

Instances of this error (1)

1. There is no stack trace or error line information available for this error

Hi DManA,

Which version of Visual Studio do you use? Did you use base control and inherited control? I never meet such problem before, if possible, could you please send the project to me(v-kiqian@microsoft.com)?

Sincerely,
Kira Qian

Hi,
Did you try to add some new components manually in the designer part?
