Here is the problem – you made your project name SHMC.BTS.RASBInterfaceTest – this turns into your .NET namespace. Since BizTalk takes the odx and turns it into C# – you have a C# namespace with BTS in it. This is cause the compiler to look into your namesapce for MessageType – and its not there. The only fix is to go into the project properties and remove BTS. from your namespace
