[Mono-list] Problem loading ASP.NET page after Mono update

[Ferdinand Funke]

Hello,
I recently updated my Mono version from 2.4 to 2.4.2.3. After updating I 
was not able to load my main ASP.NET project any more. Here is the error:
Server Error in '/' Application
The classes in the module cannot be loaded.

Description: HTTP 500. Error processing request.

Stack Trace:

System.Reflection.ReflectionTypeLoadException: The classes in the module 
cannot be loaded.

Version information: Mono Version: 2.0.50727.1433; ASP.NET Version: 
2.0.50727.1433

Moreover xsp2 gave me some errors as well:

Before the update everything was working fine but now I do not really 
know what to do. Is there anybody who can give me a hint?

Best regards
