TL; DR

Oh, look, a wild Microsoft Build appeared! The Microsoft Build this year was, you know, all virtual again. As a person who is more interested in .NET and WSL development, I find it disappointing that not much of Windows development is mentioned in the entire conference. It made me miss Build 2019. While I am still not recovered from my master’s study, my laptop died right during the Build conference; I can only provide a straightforward summary of this year’s Build. Well, I think let’s dive in.

To my disappointment, there is not much new in this build. This build generally recapped everything we have so far, such as WSLg and ``wsl --install`. The only new thing I noticed is Visual Studio’s ability to debug using the browser in WSL using WSLg.

The sessions about .NET is packed with information, although there is nearly 1-digit number of sessions about it. .NET Upgrade Assistant (Help upgrade .NET project to latest version) would be possibly a great tool for me to migrate my old projects to newer version, and .NET 6 with its Single stack (only one SDK, BCL, Toolchain for cross-platform) structure made it looks really promising. Here is a quick sum up from the session:

• • Syntactic Simplications
    • In-line comparison (Equals in {} in Writeline can be simplified to just ==)
  • Record structs
    • record class/struct
  • Improvements to lambdas and auto-properties
    • init for simple initialization
    • required option for init items
    • => for init, get and set
    • !! for check incoming variable
    • global using for all dependency accorss
    • namespace <name>;can be used instead of the oldnamespace <name> {}

• Web API (minimal)

• .NET MAUI

  • dotnet new maui
  • Speacial Resources type (Maui*)
  • Would be really great for some projects

• Blazor

• WebAssembly ahead-of-time compilation

• Error boundaries

• Razor component type inference & generic type constraints

• Dynamic Components

• Blazor state persistence during prendering

• Fluent UI

• ASP.NET Core

  • Runtime
    • HTTP/3
    • HTTP logging middleware
    • Shadow copying for IIS deployment
    • OpenTelementary support
  • API
    • Minimal APIs
      • start.cs is now optional
      • lambda support
      • provide experience similar to NodeJS
    • Async streaming
    • IAsyncDisposable support
    • gRPC client retries & load balancing
  • Web UI
    • CSS isolation for Pages & Views
    • Improved SPA support
