I am trying to modify a .net mapguide web application using:

MGOS 2.2 RC4 64bit
visual studio 2010
windows 7 64 bit
iis 7.5

I receive the following warning in visual studio: ASP.NET runtime error:
Could not load file or assembly 'OSGEO.MapGuide.Foundation' or one of its
dependencies.  An attempt was made to load a program with an incorrect

and when open my web page I get:

The type initializer for 'OSGEO.Mapguide.MapguideApiPINVOKE' threw and

I have read the following post and followed its suggestions with no luck:


This application was working great on another windows 7 64 bit machine but

corflags for all shows:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC>corflags.exe
Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  4.0.30319.1

Version   : v2.0.50727
CLR Header: 2.5
PE        : PE32+
CorFlags  : 1
ILONLY    : 1
32BIT     : 0
Signed    : 0

Target framework is .net 2.0
Build Platform is Any CPU
MapGuideApplicationPool (of which my application is a member) Enable 32-Bit
Applications is False and .NET Framework Version is v2.0

Is anyone using this type of configuration?  Am I missing  something?  Would
I be better to use the 32 bit version of Mapguide?
