Loading user control from class library causes TypeLoadException

[Dave]

I have made a class library which contains a user control I made. When I create an instance of this control in the form designer, it appears correctly, no problems. But then when i try to compile the project, I get the following exception:

 

An unhandled exception of type 'System.TypeLoadException' occurred in MyFrame.exe

 

Additional information: Could not load type MyFrameControl from assembly MyFrame, Version=1.0.1442.31213, Culture=neutral, PublicKeyToken=null.

 

What am I doing wrong?!

Is the CopyLocal property for the assembly set to true in the solution explorer? It sounds like maybe it's not getting copied to the output directory, in which case .net wouldn't be able to locate it at runtime.

that's sorted it - thanks!

problem

 

iam having the same problem.

how could i solve this problem.

If you are having the same problem, but you could not solve that problem using the answer I gave above, then you probably have a different problem.

 

It looks like we have a problem.

ITs property is true

 

either its true or false give me the same error.

In the designer it shows me the control but in red "Error creating control".

 

I think i am missing something.

Is it necessary to make public key token for this.

 

Anxioulsy waiting for ur reply.
