I have a UWP app that uses the FullTrustProcessLauncher to start a full trust process that registers a COM object. However, when the UWP app tries to create the registered COM object CoCreateInstance returns REGDB_E_CLASSNOTREG. The COM server is registered in the package manifest though the extension windows.comServer. I can successfully create the COM object in unpackaged Win32 process.
How do I properly set up and register my full trust COM server so that my UWP app can create the COM object?
there is a way to perform inter-pocess communication between UWP apps and Win32 apps with out of process COM servers.
