+Summary: Generics interop problem with Mono and .NET 2.0
+
+I've got a bit of code that uses SharpDevelop 2.0 dlls built on VS.NET 2005
+(proper release). I'm building on Mono:
+
+gmcs -debug -out:editor.exe -r:ICSharpCode.Core.dll
+-r:ICSharpCode.SharpDevelop.dll -r:ICSharpCode.NRefactory.dll
+-pkg:gtk-sharp-2.0 editor.cs
+
+When I run editor.exe:
+
+$ mono editor.exe
+
+** (<unknown>:26207): WARNING **: type 0x15 not handled
+
+** ERROR **: file marshal.c: line 2053 (mono_mb_emit_restore_result):
+should not be reached
+aborting...
+Aborted
+
+
+At the end of the trace, we can see the problem is the return value of a
+property:
+
+. . LEAVE: ICSharpCode.NRefactory.Parser.AST.UsingDeclaration:get_Usings
+()(unknown return type 15)
+
+
+The relevant bit of the trace:

+
+
+I can provide the prebuilt SharpDevelop 2.0 dlls (built from their SVN) if
+you get in touch with me on IRC or by email.
+
+Will attach the code that uses these assemblies and triggers the bug ASAP.
+Example works on VS.NET 2005.
