 [.NET 5](https://dotnet.microsoft.com/en-us/download/dotnet/5.0) was released in November 2020 with the goal of unifying development for desktop, Web, cloud, mobile, gaming, IoT, and AI applications. The earlier setup goal was to produce a single .NET runtime and framework, cross-platform, integrating the best features of .NET Core, .NET Framework, Xamarin, and Mono. However, due to the global health pandemic, the unification was postponed to .NET 6. .NET 5 is a shared code base for .NET Core, Mono, Xamarin, and future .NET implementations. Also, target framework names (TFMs), which express which version of .NET targeting, are updated, so we now have net5.0. This is for code that runs everywhere. It combines and replaces the netcoreapp and netstandard names and net5.0-windows that represent OS-specific flavors of .NET 5 that include net5.0 plus OS-specific bindings.
