Foolishly, I was in a hurry and didn't backup my box before allowing this update, which I always do. A good lesson here for everyone. My app was stable, but now it will not run compiled with .NET native. Debug build is OK, although I'm annoyed that the command bar theme has changed. .NET Native states it compiles OK, but it crashes every time. This is a UWP app based on Template 10. Will not run within or outside of the IDE. When run within the IDE, I get...
