 ## Specifying a .NET version
 
 To use a preinstalled version of the .NET Core SDK on a {% data variables.product.prodname_dotcom %}-hosted runner, use the `setup-dotnet` action. This action finds a specific version of .NET from the tools cache on each runner, and adds the necessary binaries to `PATH`. These changes will persist for the remainder of the job.

 The `setup-dotnet` action is the recommended way of using .NET with {% data variables.product.prodname_actions %}, because it ensures consistent behavior across different runners and different versions of .NET. If you are using a self-hosted runner, you must install .NET and add it to `PATH`. For more information, see the [`setup-dotnet`](https://github.com/marketplace/actions/setup-net-core-sdk) action.
