Attached is a testcase with ASP.Net MVC 2 that works on .Net but fails on Mono
2.6.4.

This appears to prevent usage of the generic extensions methods for HtmlHelper,
new in asp.net mvc2, like TextBoxFor(), etc.


Server Error in '/' Application
The property Mvc2TextBoxFor.Models.TestModel.Name could not be found.

Description: HTTP 500. Error processing request.

Note that if a try to use a property that really doesn't exist, I get a
compilation error as expected. This seems to be something related to reflection
or Expression.

Reproducible: Always
