Loading a Power BI dashboard tile in a XAML app

README.md

This example assumes you already know how to get an OAuth token and an embed URL for your tile. Use this documentation to get started: https://msdn.microsoft.com/en-US/library/mt450498.aspx#gettile

1. Add a JS file to your project, with contents of "postActionLoadTile.js"
2. Reference the JS file in your WebView string <script src=\"ms-appx-web:///postActionLoadTile.js\"></script>
3. Use the WebView's InvokeScriptAsync method to call the postActionLoadTile JS function.
