The dnr.dll file contains invalid IL code:


    .method public static 
           default valuetype [mscorlib]System.Reflection.Emit.OpCode getOPCode
(string code)  cil managed 
    {
            ...
            ldnull
            ret
    }

>PEVerify.exe /il dnr.dll 

Microsoft (R) .NET Framework PE Verifier.  Version  4.0.30319.1
