+Ok, I have fixed the bug in the compiler (this is in fact an
+interesting setup).  The problem is that the Mono Runtime is not
+currently able to generate the code for it, here is the output:
+
+no implementation for interface method
+TestCase.IDataAdapter::get_TableMappings() in class TestCase.XDataAdapter
+METHOD .ctor()
+
+** ERROR **: file class.c: line 687 (mono_class_setup_vtable): should
+not be reached
+aborting...
+Aborted
+
+Here is the updated sample which compiles and runs on .NET with CSC
+and MCS:
+
+using System;
+namespace TestCase
+{
+	public interface IDataAdapter
+	{
+		string TableMappings {get;}
+	}
+	public interface IDbDataAdapter : IDataAdapter
+	{		
+	}
+	public class DataAdapter : IDataAdapter
+	{
+		string IDataAdapter.TableMappings 
+		{
+			get{return "hello idataadapter.tablemappings";}
+		}
+		public string TableMappings 
+		{
+			get{return "hello Dataadapter.tablemappings";}
+		}
+	}	
+
+	public class DbDataAdapter : DataAdapter
+	{
+	}
+
+	public class XDataAdapter : DbDataAdapter, IDbDataAdapter
+	{
+	}
+
+class X {
+	static void Main ()
+	{
+		XDataAdapter d = new XDataAdapter ();
+		IDataAdapter i = d;
+
+		Console.WriteLine ("ID=" + i.TableMappings);
+		Console.WriteLine ("DA=" + d.TableMappings);
+	}
+}
+}
+
+I am re-assigning this to the Mono/Runtime now.
