Testing Win2D canvases inside a React Native UWP context.
You're going to need NodeJS (LTS is fine), and I highly recommend getting Yarn too, because this takes a while with NPM (which is included with NodeJS). These commands take care of the React Native part.
npm install -g react-native-cli
git clone https://github.com/JulienNoble/Win2DTest.git
cd Win2DTest
yarn install
react-native start
You should have a message saying Loading dependency graph, done., which means you're ready to go on. The packager, which is started with the last command, is used to serve assets in development mode.
For the UWP part, open windows/Win2DTest.sln, set your target to Debug x64 (or x86) on local computer and launch.
App itself shows nothing, but there are debug outputs from the canvas context inside Win2DImageView.cs. Be sure to check Visual Studio's console output to see if it works.
