designer can't find custom controls

[Zexor]

I have added some custom controls to my solution. They are in a different file than the main file. The designer usually will pick it up and see it as a tool and add it to the toolbox. But sometime for some reason it doesnt show there and the designer give a bunch of error cause it cant find the tool. But i can still run the program fine with all the designer error. How can i fix this? Sometime i just close the program and reopen, its fine again.

Try to check its referenced dll. Maybe the path it used to reference cannot be found.

With file, do you mean assembly (.dll) or just code file?
If they're in the same assembly: always put your custom and usercontrols in a separate assembly .

You are probably running a previous version of your program?
