There were some changes to the MapGuide Unmanaged dlls between 2.0 and 2.1.

You need an updated MapGuideDotNetApi:

I have just uninstalled MGOS2.0 and installed MGOS2.1 on Vista.
It runs very well. I can access MSOS server and view the map with Maestro
r4586.

But if I intend to access the server with LocalNativeConnection of
MaestroAPI (The code is as follows), one exception will be thrown.

Impossible Get Entry Point 'CSharp_MgSiteConnectionToMgGuardDisposable' in
DLL 'MapGuideUnmanagedApi'

If use 'HttpServerConnection', it runs normally.

I serched the forum and found some discussions, but no suitable answers for
me.

thanks for any helps!
