StereoKit: Develop branch: OOB code builds UWP fails to start: A dependent dll was not found.

Description

UPDATE: The issue is more than a missing dll. All builds since preview 9 fail to run locally on Windows or fail to run in HoloLens. Preview 9 runs on Windows and runs in HoloLens. The latest preview 1639 has the errors mentioned below but this is a deeper problem on the Windows platform.

Download a fresh SK Develop branch zip file. Unblock the file in properties. Extract all files to a folder. Open folder properties and uncheck the readonly mark, and select folders, subfolders, and files. Follow instructions int Build.md document for Windows only. Note now you must also drop the Maui project from the solution. To build set StereoKit (Core/SteroeoKit) as startup project. Next open solution configuration manager and check only these projects: StereoKit, StereoKitC, and StereoKitC_UWP. Build the solution. Then open configuration manager and uncheck the three projects just built. (The order of build execution in VS will fail if you don’t build the core components first.) In configuration manager check StereoKitTest to build and deploy. Then set StereoKitTest as the startup project. Build and run. This should operate normally on a Windows computer.

This is where it fails: Assuming you have followed the steps above, in configuration manager uncheck all projects. Next check only StereoKitTest_UWP to build and deploy. Then set StereoKitTest_UWP as the startup project. Build will succeed. Next run the app in VS debugger by starting the app. The app will build and launch. The app will momentarily start then immediately close with an error that application cannot start with instructions to see the output Window (shown below). Windows UWP apps that fail to start do not report to the debugger what has caused the failure. Knowing only that a least one dependent file was missing I needed to determine which and if there were others. Using Process Monitor, I captured all the processes Windows executed. From this (see zipped csv) it seems that a number of dependent files are not in the folder deployed by the UWP. SK_Process_Logfile.zip
