Screenshot of Assembly Browser with exception

When I select System.Array.CreateInstance (Type, int) in Assembly Browser, there is an exception info in the window where should be a source code (see the sceenshot):

Decompilation failed: 
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Select DataSet in the editor, press F12 and get the following exception (shown in the window where should be signatures of the DataSet's members):

Comment 2 Stas Kalashnikov 2011-10-27 04:01:13 UTC
Last bug with DataSet is in MonoDevelop 2.8.1 (Windows 7).

There is already no bug with System.Array.CreateInstance in 2.8.1. Assembly Browser shows correct method signature:

using System;
using System.Security;
[SecuritySafeCritical ]
public static Array CreateInstance (Type elementType, int length)
{
}

Cecil decompiler is no longer be used.
