Hello,
I have downloaded the trial version of winforms. I cant add most of the components from toolbox, it gives the following error.


Also every time i built my project it gives to following error.


My System is:
Windows 7
Visual Studio 2010 with SP1

I have solved it.
the problem was that i had copied the Form_Shown and Form_FormClosed events from another form. i recreated the events then the problem solved.
