I'm having the same problem as Jadeia (07/07/04) but her solution hasn't worked for me.
I have been using Visual Studio Enterprise 2003. It has been fine for ages. I haven't installed anything recently that should affect it.
Now I am unable to add forms to new or existing projects, I just get the 'the operation could not be completed' error.
I have tried everthing I can think of. I uninstalled visual studio, and everything relating to the .NET framework.
Then I reinstalled .NET (1.1) and the service pack.
Then I reinstalled visual studio.
Still the same problem. This is really getting me down as my work has ground to a halt, and I would appreciate any insight that you may have.
The solution provided does not resolve as the page below does not exist.
can any one who resloved this problem send me the commands that has been executed.
