The release of .NET Core 3 follows it moving to Release Candidate status a week ago. If you’re unfamiliar with the latest version of Microsoft’s open source framework, it has a sea of changes. For example, C# 8.0 and F# 4.7 are part of the .NET Core experience now, which .NET Standard has been bumped to version 2.1. Elsewhere, .NET Core 3 comes with support for Windows Desktop apps via WinForms. Elsewhere, developers can now leverage a high-performance JSON API, new support for ARM chips, support for Raspberry Pi, and what Microsoft describes as “hardened” support for Docker. At the moment, .NET Core 3 is rolling out as version 3.0. This is the release build, but Microsoft says .NET Core 3.1 will be the long-term support build and will arrive in November. To run the latest version of the framework, users must have Visual Studio 2019 16.3 or later on Windows, Visual Studio for Mac 8.3 or later, of the newest Visual Studio Code on other platforms.

Alongside the release of the latest .NET Core version, Microsoft also rolled out its latest ASP.NET Core. With this update, developers can now build web applications with C# by leveraging Blazor, as an alternative to JavaScript. Also in the new version, Microsoft says more security is available through HTTP/2 on by default.
.NET 5
While showcasing .NET Core 3 at Build 2019 in May, Microsoft also announced .NET 5. The company said the release will replace the naming convention of .NET Core and .NET Framework, rolling both into a single product. In its explanation blog post, Microsoft says .NET 5 will be a merger of classic .NET Framework with the open source Core. This will create a single .NET platform, something users of the software framework have been asking for.
