About an exception during running the example for WinUI 3.0 demo.

OneCoder 21 Reputation points

I had downloaded the example, "Build2020Demo", for WinUI 3.0 demo. at "https://github.com/microsoft/WinUI-3-Demos".

The example was built with the option "x64" in Visual Studio 2019 Community and successfully done.

But, when I run the built example, I got "Unhandled exception" as can be seen in the attached image.

I have run the example in Visual Studio with "Start New Instance".

Is this exception because some components are missed?

A high-level, general-purpose programming language, created as an extension of the C programming language, that has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation.

    I compiled it as x86 :
