ASP.NET Blazor, which allows developers to build interactive web UIs with C# instead of JavaScript, now supports WebAssembly. This added capability means developers can build client-side web apps that run completely in the browser with .NET. These compiled applications run faster and with less memory than JavaScript.
It also allows developers to create Progressive Web Apps with full offline support. Further, because .NET is running on WebAssembly, developers can reuse code and libraries from the entire .NET ecosystem.
