Remarks
For more information about using the ID3D11ClassLinkage interface, see Dynamic Linking.
A class instance must have at least 1 data member in order to be available for the runtime to use with ID3D11ClassLinkage::GetClassInstance. Any instance with no members will be optimized out of a compiled shader blob as a zero-sized object. If you have a class with no data members, use ID3D11ClassLinkage::CreateClassInstance instead.
