Distributions

The following distributions are available for all operating systems:

  • .NET SDK: includes tools for building and testing applications, and includes the runtime distributions that follow.
  • .NET Runtime: includes the .NET runtime and libraries, enabling running console applications.
  • ASP.NET Core Runtime: includes the .NET and ASP.NET Core runtimes, enabling running console, and web applications.

We recommend that you install the .NET SDK to develop and build applications, and to install one of the runtime packages (like ASP.NET Core) to (exclusively) run applications.

Container images are provided for Linux (Alpine, Debian, Ubuntu, Azure Linux, and distroless variants of Ubuntu and Azure Linux) and Windows (Nano Server and Server Core).
