Errors in MddBootstrapInitialize often mean that the installed Windows App SDK Runtime is != the Windows App SDK NuGet package version
(or the Runtime is not correctly installed)

I am getting some experience with Windows App SDK and am running the "Hello World" Console practice app (see Tutorial—Use the bootstrapper API in a non-MSIX-packaged app that uses the Windows App SDK). Running the app gives me this error: Error 0x80070491 in MddBootstrapInitialize(0x00010000, , 0.0.0.0)
Looking on the Common error codes page, I don't see an entry for the error. Does anyone know what this code means?
Windows development | Windows App SDK
Developer technologies | C++
Developer technologies | C++
A high-level, general-purpose programming language, created as an extension of the C programming language, that has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation.

If your existing project is a C++ project, and you want to call Windows Runtime APIs in the Windows App SDK, then you'll need to add support for C++/WinRT

2022-07-16T19:20:35.927+00:00 None. I only write native C++ code. I was under the understanding that project reunion would eventually let native C++ apps call Windows App SDK like a library. I don't mind Init and Shutdown of a separate process that does COM apartment work, but I don't see the necessity of installing a whole dotnet Runtime superstructure. Is that what you are saying is necessary?
