All biztalk schema get turned into C# classes (a class is one of the .NET types, such as class, structure, enum, interface).
Click on the .xsd file in Solution Explorer, the property window shows you the \”Type Name\” property – make sure it doesn’t have any weird characters or blanks in it.
To explore more, create a simple schema, compile it, then use the .NET ILDASM utility (Intermediate Language Disassembler) to view the .DLL. You can then see the manifest and typenames.
There even a free download utility that will capture and save the C# code that Biztalk generates (normally Biztalk generates it, compiles the code, then deletes it).
