Hey,

I have a solution with about 5 projects, the main (startup) project is a windows forms project while the others are control libraries that contain some custom controls. The main winforms project however also contains some custom controls.

Recently, the controls in the main winforms project have stopped appearing in my toolbox. The controls from the other control library projects appear just fine, but none of the controls in my main project will show...

Some of the projects are VB, some are C#.

I have tried everything I know to fix it:
  • Delete bin/debug folders and restart
  • Build, build, build, build, and build
  • Target the same .NET Framework version and CPU platform in all projects
  • Build again

Nothing works...

All projects target .NET Framework 4.0 and compile for the x86 platform (since I am using Access db). All projects build successfully, no errors. I can run the solution just fine. I can even declare and add the controls in code and they work just fine. They just don't show up in the toolbox so I can't drag them to my form and I have to dig into the designer code everytime, which is really annoying!

Any idea what could cause this beside what I've already tried??
