Microsoft has released the 3.2.0 Preview 1 of Blazor WebAssembly, which adds support for a SignalR client, simplified startup and improved download size.
Blazor is a framework for building web applications using C#, HTML and CSS. The C# code is used for both client and server functionality meaning that duplicated business logic is no longer an issue. The C# code is compiling to run on WebAssembly. The framework uses .NET Standard 2.0 so you can include standard libraries from Microsoft or 3rd parties. Code running in WebAssembly is sandboxed so can’t access APIs such as accessing the file system.
