Calling UWP api from unmanaged DLL

Question

Currently I have a Credential Provider implemented in C++ and I would like to incorporate BLE communication to it. This is provided in Windows 10 by the UWP class Windows.Devices.Bluetooth.GenericAttributeProfile.GattServiceProvider .

I tried to load to make a UWP DLL implementing the function and load it using LoadLibrary but got an ERROR_NOT_APPCONTAINER

Is it possible to use the UWP APIs from some unmanaged C++ code?

Answer 1

You can not load UWP dll inside of desktop application. However it is possible to use many UWP APIs directly as they are essentially COM-based. Typically anything not depending on application context and having public activation factory (constructor) can be used. For example see How to: Activate and Use a Windows Runtime Component Using WRL .
