DIA SDK Throws NotImplementedException

I am trying to inspect a .pdb using the DIA SDK from C# but I cannot get the user defined types using this code:

string pdbFileName = @"c:\test.pdb";
var sourceClass = new DiaSourceClass();
sourceClass.loadDataFromPdb(pdbFileName);
IDiaSession session;
sourceClass.openSession(out session);    

IDiaEnumSymbols symbols;
session.globalScope.findChildren(SymTagEnum.SymTagUDT, null, 0, out symbols);

I get different results if I reference dia2.tlb or dia2.dll from my C# project.

If I reference dia2.tlb, the function call completes successfully, but I get no symbols back. This is the same if I pass SymTagEnum.SymTagPublicSymbol to findChildren too.

If I reference dia2.dll, the function throws a NotImplementedException instead. In this case, passing SymTagPublicSymbol to findChildren does return symbols.

Has anyone encountered this? I think referencing the .dll is correct, but I do not know why I get the NotImplementedException thrown.

IDL/DLL

I created the dia2.tlb and dia2.dll using the commands in a VS command prompt:

cd C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional

midl /I "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\DIA SDK\idl";"C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\DIA SDK\include" dia2.idl /tlb dia2.tlb

tlbimp dia2.tlb

Many thanks.
