.NET Framework.Compact SP2 : Pocket PC 2002

I have created a Designer support DateTimePicker with CultureInfo support.
Following the instructions explained at :
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/
customctrlscompactfx.asp

I got this to work in the Emulator.

However when I run the program on my Maschine (XDA I - Pocket PC 2002 -
German) I recieve the following error
when the program starts:
TypeLoadException the Typ "System.Windows.Forms.Control" of the Assembly
"System.Windows.Forms, Version=1.0.5000.0,Culture=neutral, ....

The resulting .dll is copied to the Program Files Directory togeather with
the .exe

In the AssemblyInfo.cs :

[assembly: AssemblyCulture("")]
#if DESIGN
[assembly:
System.CF.Design.RuntimeAssembly("mj10777.DateTimePicker,Version=1.0.1.0,
Culture=neutral, PublicKeyToken=null")]
#endif

The goal is for this Control to run on all Maschines without further
changes.

This error also accured with the project found in the link above (Emulator
OK ; Maschine failed).

What could the cause be?

I have noticed that this aloso happens on the Emulator when SP2 has been
installed.
After a coldstart this does not happen.

Mark,

What is the PublicKeyToken in the TypeLoadException message?  Also, have
you verified that NETCF installed correctly?  (Does a simple form run?)

PublicKeyToken=B77A5C561934E089

Everything else works correctly.
The source of this Control where the .cs file is included in a Project runs
correctly.
Only when included as Control does it fail with SP2 (Emulator/Mashine), SP1
runs correctly on Emulator.

This also happens (same PublicKeyToken) with the project found at

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/
customctrlscompactfx.asp

This PublicKeyToken belongs to the desktop framework; correct NETCF
references have PKT=969db8053d3322ac.  There was a bug where we would
resolve desktop references like this in v1 RTM and SP1 which was fixed in
SP2.  Unfortunately, this makes some libraries which appeared to work
correctly before fail under SP2.

MSDN article you are following is attempting to show you how to combine a
desktop project with a smart device project, which is a bit dangerous.  You
have to be very careful to reference ONLY Compact Framework libraries or
you will get the problem you are seeing.  Also note that this article
references pre-RTM NETCF (version 1.0.3300.0), and not everything in it is
guaranteed to be up to date.
