+Summary: System.Reflection.Emit.ModuleBuilder.DefineType misbehavior when parent is null
+
+Description of Problem:
+Passing null to ModuleBuilder.DefineType results in generating invalid
+metadata.
+
+Steps to reproduce the problem:
+1. Define a class using ModuleBuilder.DefineType and pass a null parent.
+2. Persist the assembly and run it.
+
+Actual Results:
+The runtime crashes due to invalid metadata.
+
+Expected Results:
+For classes, null parent is equivalent to System.Object (as in CLR).
+
+How often does this happen? 
+Always.
