I have come across what I think is the same error when referencing a device
dll project from a desktop visual basic exe project (they weren't in the
same solution).
What I found would happen is that when the device dll was built visual
studio would copy a number of compact framework assemblies into the debug or
release folder along with the dll (usually Microsoft.WindowsCE.Forms.dll and
System.Windows.Forms.dll).
In the desktop project when you add a reference to the dll, it sees these
additional dlls and sets the path up as a default reference path for the
desktop project. This means your link to System.Windows.Forms.dll now
incorrectly points to the device version. This explains the reference to AGL
because this is a namespace within the compact framework
System.Windows.Forms assembly - which has a drastically different
architecture from the desktop version.
What cured it for me was to go into the project properties for the desktop
application, manually remove the reference path, and delete the
System.Windows.Forms.dll from the output folder of the device dll project.
However occasionally it still decides to automatically change it back for me
:-(
