I have a global.json that looks like this:

{
  "sdk": {
    "version": "8.0.301",
    "rollForward": "latestFeature"
  }
}

This means, as far as I know, that I want it to accept 8.0.xxx as long as it’s not lower than 8.0.301. For example, both 8.0.302 and 8.0.400 would work, but 8.1.x or x.x.x wouldn’t.

The problem is that my Azure Pipeline only wants to install 8.0.301. At the time of writing, 8.0.302 is available, which is backed up by Microsoft’s official download page.

My Azure pipeline task that installs the .NET SDK is as follows:

- task: UseDotNet@2
  displayName: "Install .NET SDK"
    inputs:
      packageType: sdk
      useGlobalJson: true

But when this runs, I see the following logs:

Why would it install 8.0.301 even though 8.0.302 should get downloaded?
