.NET is an open-source, general-purpose development platform
maintained by Microsoft and the .NET community on GitHub.  It's
cross-platform (supporting Windows, macOS, and Linux) and can be used to
build device, cloud, and IoT applications.

This package contains everything you need to run a .NET 6.0 application.
If you want to build apps, install .NET 6.0 SDK (dotnet-sdk-6.0), which
contains this runtime too.
