Doesn't compile with VS2019. Too many errors to sort through.

I did get it to build with VS2019, but it crashes instantly. Here are a couple pointers:

1. In the SamplesNative project properties, change Platform Toolset to Visual Studio 2019 (v142)
2. Manage NuGet packages for the solution and update Win2D.uwp to 1.25 and Microsoft.Xaml.Behaviors.Uwp.Managed to whatever version is available and then Microsoft.NETCore.UniversalWindowsPlatform to 6.2.12

Run... aaannnd crash...

I needed to try a sample and better understand it, so I was able to get it to build in VS 2019. Submitted PR #350
