What are LoaderExceptions?

[steve bull]

I have a project with various forms but when I try to view the designer for one of the forms I get the following error messages -
even though the project atually compiles :


Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.



Instead of the form displaying I get :

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Does anyone have any idea how I should go about getting rid of these errors?


Thanks for any help,

I think you mean the bug somebody already found a work-around for in the
"User Control Designer Errors is [sic] VS2005 RC1" thread.

Change your AssemblyInfo.cs files in the UserControls DLLs as follows:
[assembly: AssemblyVersion("5.5.5")]

Where 5.5.5 is any hard-coded version number. The problem was the .* in it
causing the UserControl to have an auto-generated version that's different
than what your other DLL is expecting. As soon as you recompile it with
changes or something, you get the Unable to Load error.

BTW - Notice I called it a BUG. I truly believe it's a bug. There's a
rational explanation for what it's doing, but it is bound to cause a little
frustration for a lot of people.

Let me know if it works.
