Blazor is no longer an experimental project from Microsoft. Blazor allows to write C# and .NET Code to add client-side functionality with Web applications. The first part of Blazor that's released with .NET Core 3.0 offers server-side Blazor functionality. Client-side Blazor using WebAssembly has a release planned with .NET Core 5 in 2020. In this session you get an introduction to Blazor, learn how you can use ASP.NET Core Razor syntax to create Blazor components. You'll see server-side Blazor in action, and what's needed to change it to the upcoming client-side Blazor, and what's going on behind the scenes.
