-> **Note**: The action supports `latest*` variants of the [rollForward](https://learn.microsoft.com/en-us/dotnet/core/tools/global-json#rollforward) field in `global.json`. When set to `latestPatch`, `latestFeature`, `latestMinor`, or `latestMajor`, the action installs the appropriate SDK version.

When set to `latestPatch`, `latestFeature`, `latestMinor`, or `latestMajor`, the action installs the appropriate SDK version. For prerelease versions, the exact pinned version is always installed regardless of the `rollForward` setting.
 
 ## Caching NuGet Packages
 The action has a built-in functionality for caching and restoring dependencies. It uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood for caching global packages data but requires less configuration settings. The `cache` input is optional, and caching is turned off by default.
