+Summary: Unable to generate static interface methods using Reflection.Emit
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+If MethodAttributes.Static is passed to TypeBuilder.DefineMethod, it throws
+exception "Interface method must be abstract and virtual." There's nothing
+wrong about static methods in interfaces and there are compilers (e.g.
+Phalanger) that actually use this for certain helpers. Not to mention that
+it works in CLR :)
+
+Steps to reproduce the problem:
+
+using System;
+using System.Reflection;
+using System.Reflection.Emit;
+
+namespace ConsoleApplication1
+{
+	class Program
+	{
+		static void Main(string[] args)
+		{
+			AssemblyBuilder ab = AppDomain.CurrentDomain.DefineDynamicAssembly(
+				new AssemblyName("ass"),
+				AssemblyBuilderAccess.Run);
+
+			ModuleBuilder mb = ab.DefineDynamicModule("mod");
+			
+			TypeBuilder tb = mb.DefineType(
+				"ILikeDotNet",
+				TypeAttributes.Public | TypeAttributes.Abstract |
+TypeAttributes.Interface);
+
+			MethodBuilder fb = tb.DefineMethod(
+				"Foo",
+				MethodAttributes.Public | MethodAttributes.Static,
+				typeof(void),
+				Type.EmptyTypes);
+			
+			fb.GetILGenerator().Emit(OpCodes.Ret);
+
+			tb.CreateType();
+		}
+	}
+}
+
+Actual Results:
+Unhandled Exception: System.ArgumentException: attributes
+Parameter name: Interface method must be abstract and virtual.
+
+Expected Results:
+-
+
+How often does this happen? 
+Always.
