Blazor is a new web UI framework based on C#, Razor, and HTML that runs in the browser via WebAssembly.
Blazor greatly simplifies the task of building fast and beautiful single-page applications that run in any browser. It does this by enabling developers to write .NET-based web apps that run client-side in web browsers using open web standards.
If you already use .NET, this completes the picture: you’ll be able to use your skills for browser-based development in addition to building server and cloud-based services, native mobile/desktop apps, and games. If you don’t yet use .NET, our hope is that the productivity and simplicity benefits of Blazor will be compelling enough that you will try it.
To get started with Blazor go to https://blazor.net, click on "Get Started", and then follow the instructions.
Thanks for trying Blazor!
