User(s) can reproduce this bug

When you create an add-in with the wizard and make this call:

toolBar = commandBars.Add(Name:="My toolbar", Position:=Microsoft.VisualStudio.CommandBars.MsoBarPosition.msoBarTop, Temporary:=True)

you get the exception:

"Object must be the same type as the enum. The type passed in was 'Microsoft.VisualStudio.CommandBars.MsoBarPosition'; the enum type was 'Microsoft.VisualStudio.CommandBars.MsoBarPosition'."

Visual Studio 2010 Beta 1

With VS 2010 Beta 1, create a VB.NET add-in with the add-in wizard and add the code of the attached file.

Debug the add-in.

"Object must be the same type as the enum. The type passed in was 'Microsoft.VisualStudio.CommandBars.MsoBarPosition'; the enum type was 'Microsoft.VisualStudio.CommandBars.MsoBarPosition'."

No exception.

This problems seems to happen because the add-in wizard uses the Microsoft.VisualStudio.CommandBars reference with the "Embed Interop Types" property set to True, and the CommandBars.Add call performs some type checking. So, either don't perform the type checking, or make the wizard to set that property to False (which solves the problem).
