## What it is
The repository for the .NET Standard specification, which defines a common set of .NET APIs that libraries can target across .NET implementations. It is now in maintenance mode, with future development moved to dotnet/runtime and new versions of .NET Standard no longer planned.

## Use cases
- understand what .NET Standard is and which APIs it covers
- decide which target framework to use for a .NET library
- find guidance on migrating from netstandard to net6.0+ targets
- look up version compatibility between .NET implementations

## When to choose
- you need historical reference material on .NET Standard versions
- you maintain an older library still targeting netstandard2.0/2.1
- you want to understand .NET API unification history

## When to avoid
- you are starting a new .NET library - target net6.0 or later instead
- you need the latest .NET API surface or runtime code - use dotnet/runtime
- you want active development or new .NET Standard versions - none are planned
