Description

Description:
Downloads and installs not needed runtime

Task version:
4.3.1

Platform:

  • Ubuntu
  • macOS
  • Windows

Runner type:

  • Hosted
  • Self-hosted

Repro steps:

      - name: Setup .NET
        uses: actions/setup-dotnet@v4
        with:
          dotnet-version: '9.0.203'

Expected behavior:
Tested host has .NET SDK installed:
9.0.203 [C:\Program Files\dotnet\sdk]

Either of these two runtimes on the tested host get used:
Microsoft.NETCore.App 9.0.2 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 9.0.4 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

Actual behavior:
dotnet-install: Downloaded file https://builds.dotnet.microsoft.com/dotnet/Runtime/8.0.16/dotnet-runtime-8.0.16-win-x64.zip size is 33292304 bytes.

Research direction

Start at the actions/setup-dotnet@v4 entry point and trace how the requested .NET SDK version is checked against installed SDKs and runtimes. Reproduce the shown workflow on Ubuntu, macOS, and Windows, then verify that an installed 9.0.203 SDK and its available runtimes no longer trigger a download of Runtime 8.0.16.
