I'm studying the advancement of Mono with WindowsForms 2.0, and a sample app
need some functionnality not implemented in System.Data.DataViewManager. The
sample app run correctly on ms.NET.

I tried to have a minimal test case.

I'm using Windows, Visual Studio and the mono 20080620 tarball on cygwin.

Steps to Reproduce: run source code below
Actual Results: NIEX : The application crashed.
Expected Results: a blank form
