The mlapp.tlb type library indicates that the MLApp coclass implements IMLApp. However, trying to obtain this interface fails:
CoCreateInstance(CLSID_MLApp, NULL, CLSCTX_LOCAL_SERVER, IID_IMLApp, (void **)&mlapp)
Creating using IUnknown or DIMLApp works, but then QueryInterface to get IMLApp fails. Using the dispatch interface from C++ is very annoying. Why is the IMLApp interface not available?

Hello Peter,
Thank you for your feedback. I have created an enhancement request for this feature based on your feedback. The development team may consider this for a future MATLAB release.
