Earlier this year, Microsoft announced their support for Blazor, and now Frank A. Krueger has developed the Ooui library which allows C# or F# to be used to write applications that run in the browser. Ooui can target WASM, enabling Xamarin.Forms app to be deployed in web assembly and the result runs entirely in-browser without the need for an application server.
