Hello. A couple of comments. You don't mention in this writing that it is necessary to add the ProgressBarHandler class, even though it is empty. I did the exercise in MUAI .NET 7, and it was necessary to do this. Also, I suggest that IgnorePixelScaling = true, since it doesn't render with the precise units on high resolution monitors without scaling 100. Great article. Thanks for sharing.

One of the biggest advancements in C# is the foray into WebAssembly with Blazor. When others get there, C# will go a long way.

You're right, wrong route. It must be referring to ..Bin\Roslyn. TXS
