Finally the wait is over! In the .NET Conference 2019, Microsoft released the .NET Core 3.0 that now supports Windows desktop apps like WPF (Windows Presentation Foundation) and Windows Forms, along with C# 8 language features.
Here's everything that you would like to know about .NET Core 3.0 and the links to download the SDK and runtime for different platforms.
.NET Core 3.0 brings support for Windows Desktop apps built with WPF (Windows Presentation Foundation) and Windows Forms. This includes new templates and an updated XAML designer and XAML Hot Reload. The WPF designer is part of Visual Studio 2019 16.3. The Windows Forms designer is still in preview and available as a VSIX download.
The dotnet publish command supports packaging your app into a platform-specific single-file executable. This form of single EXE is effectively a self-extracting executable. It contains all dependencies, including native dependencies and resources. Thus, you can now launch the .NET Core apps directly without using the dotnet command.
.NET Core 3.0 now includes a setting that will use the IL linker tool to scan the IL of your app. This tool detects what code is required, and then trims the unused libraries.
C# 8.0 language support adds the new features like async streams, range/index, more patterns and nullable reference types. The F# 4.7 focuses on making some thing easier with implicit yield expressions and some syntax relaxations. It also includes support for LangVersion, and ships with nameof and opening of static classes in preview.
The .NET Standard 2.1 increases the set of types you can now use with both .NET Core and Xamarin. The .NET Standard 2.1 includes types since .NET Core 2.1.
Performance is greatly improved across many components. The garbage collector uses less memory by default, often a lot less. This improvement is very beneficial for scenarios where many applications are hosted on the same server.
High performance JSON APIs have been added, for reader/writer, object model and serialization scenarios. Raspberry Pi and ARM chips are now supported to enable IoT development, including with the remote Visual Studio debugger.
