Blazor is using C# to build web pages, which isn't new, but using C# on the client with a webassembly version of .NET. It works well enough, but is limited to simple things like onClick="SomeCSharpFunction" and can not do things like getting elements by id or class. That's were Dart shines. Most will use either JavaScript or TypeScript, but I like Dart so I want to see how it is to combine Blazor Webassembly with Dart.
It would be even more interesting if there were a Dart.NET
