Is managed code is the only way to use SMO in c++???

I have to work with SQLSERVER SMO in C++. Is Managed code is the only way to work with SQLSERVER SMO in C++ ?

I have tried many ways.. but I found that using managed code is the only option. Are there other ways?

From stackoverflow

• Technically, you can expose .NET assemblies to standard COM infrastructure, but that requires changes to the source code (see this). You may try and create a COM-aware wrappers around standard SMO objects and then use them as regular COM classes in C++.
