5.3.0 breaks the installation of .NET previews when rollForward is present

[martincostello]

Description:

Consider the following global.json file:

{
  "sdk": {
    "version": "11.0.100-preview.4.26230.115",
    "allowPrerelease": false,
    "rollForward": "latestMajor",
    "paths": [
      ".dotnet",
      "$host$"
    ],
    "errorMessage": "The required version of the .NET SDK could not be found. Please run ./build.ps1 to bootstrap the .NET SDK."
  },
  "msbuild-sdks": {
    "Aspire.AppHost.Sdk": "13.3.5"
  }
}

Since updating from 5.2.0 to 5.3.0, branches using .NET 11 previews now fail to install the .NET SDK, breaking builds.

To workaround, "rollForward": "latestMajor" has to be removed.

I would expect the version specified to be installed when it is absent.

Note that despite "allowPrerelease": false being set it false, .NET always uses a preview version if explicitly asked for without needing to change that value.

Task version:

5.3.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Repro steps:

Attempt to install the .NET SDK using the above global.json.

Expected behavior:

The 11.0.100-preview.4.26230.115 SDK is installed.

Actual behavior:

The SDK is not installed as the action detects the pre-installed SDK versions to be sufficient:
