Created an attachment (id=343712)
 --> (http://bugzilla.novell.com/attachment.cgi?id=343712)
The full project in Visual Studio 2010

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; ru; rv:1.9.1.7)
Gecko/20091222 SUSE/3.5.7-1.1.1 Firefox/3.5.7

I created the project in Visual Studio 2010 for MS Windows. This is a windows
form, which must work in .Net Framework 2.0. That form has two DataGridView
objects. At start the program creates two tables (DataTable), adds them to 
DataSet object and links those tables. The program works in Windows 7 and XP
without any problems. But when I moved it to openSUSE 11.2 with Mono 2.6.1:

Mono JIT compiler version 2.6.1 (tarball Thu Dec 17 17:24:22 UTC 2009)
Copyright (C) 2002-2008 Novell, Inc and Contributors. www.mono-project.com
        TLS:           __thread
        GC:            Included Boehm (with typed GC and Parallel Mark)
        SIGSEGV:       altstack
        Notifications: epoll
        Architecture:  x86
        Disabled:      none

the program crashed at start. The full project is attached to this report.      

Reproducible: Always

Steps to Reproduce:
1. Run program  

mono KVYadmin.exe


Actual Results:  
After start I get the exception:

SUSE32:/home/d # mono KVYadmin.exe

Unhandled Exception: System.InvalidCastException: Cannot cast from source type

Expected Results:  
The windows form with two tables into two DataGridView objects.

The crash met in KVYadmin at the following string:

 m_dataSet.Relations.Add(m_relationNameTables,
m_dataSet.Tables[m_nameHostsTable].Columns[m_colMACHostsTable],
               
m_dataSet.Tables[m_nameSitesTable].Columns[m_colMACSitesTable]);
