I have copied the instructions to develop the C# Windows SDK app, PhotoViewer. I have completed all the instructions but when I run the app I get:

Hi, @watson128. There's some disparity between your screenshot and the topic that you link to. So here's what I did:

1. Your screenshot is showing the source code for the PhotoEditor sample app. So I cloned and built that sample, and it works fine. I don't get an exception on the line of code that you highlight.
2. Your issue description mentions a thing called "PhotoViewer". I'm not aware of a sample with that name. But you link to the "Tutorial: Create a simple photo viewer with WinUI 3" topic (which builds a project named SimplePhotos, which seems to be the name of your project). I followed all of the steps in that tutorial from top to bottom, and everything worked as expected.

I'll go ahead and close the issue.

Thanks!
