.NET 5.0 is Out!

On November 10th at .NET Conf 2020, Microsoft announced the general availability of .NET 5.0. This much-anticipated release of .NET also includes C# 9 and Arm64 support.

.NET 5.0 is the first major release from Microsoft that finally unified most of their .NET APIs so you can cater to your application more accurately by using only what you need. Therefore, you can eliminate everything else that might hurt performance, security, and stability. .NET 5.0 is now the one-stop-shop for building applications. Just choose your platform, features, and off you go! No need to go through the confusing and drawn-out process of choosing which versions of each package to use since everything is version 5.0.

.NET 5.0 Highlights

Richard Lander, Program Manager of the .NET Team, noted these as notable highlights in this version.

There are many important improvements in .NET 5.0:

Other luminaries of the Microsoft world have written about their areas of expertise on this release. For example:

  • Mads Torgersen, C# Lead Designer wrote about C# 9 and it's new features such as init-only properties, records (oh boy! Is this exciting...), top-level programs, improved pattern matching, target-typed new expressions, and covariant returns, etc.
  • Jeremy Likness, Senior Program Manager of the .NET Data team wrote about the new EF Core 5.0 where he highlighted 230+ enhancements, 380+ bug fixes, and revamped documentation.
  • Daniel Roth, Principal Program Manager in the ASP.NET team wrote about what's new in ASP.NET Core 5.0. There is a lot of good news on this front: MVC now supports C# 9 record types and model binding improvements; Blazor Server and Blazor WebAssembly support and improvements, built-in OpenAPI, and Swagger UI support for Web APIs. SignalR Hub filters and parallel Hub invocations, Azure AD authentication, HTTP/2, gRPC performance improvements, and much more.

There is so much to explore in this release that a single blog post would not be enough. You can download .NET 5.0, for Windows, macOS, and Linux, for x86, x64, Arm32, Arm64. Visual Studio users will need Visual Studio 2019 16.8 or later on Windows and the latest version of Visual Studio for Mac on macOS.
