C# 9

Exciting new features in C# 9

Last week at Microsoft Build, there have been a lot of exciting annoucements! .NET 5, Blazor WebAssembly, .NET MAUI, WinUI… But the thing I’m most eager to get my hands on is C# 9, which introduces many interesting new features, so let’s take a quick tour! There’s a long list, so I won’t cover all of them here, but I will highlight the ones I find the most interesting. Note: Unfortunately the new C# features aren’t supported yet in the latest SDK preview, so we can’t test them in actual projects.
