[BUG]: UseDotnetV2 - Fails silently to download

[JasonWhall]

New issue checklist

• I searched for existing GitHub issues
• I read pipeline troubleshooting guide
• I checked how to collect logs

Task name

UseDotnet

Task version

2.246.1

Issue Description

It seems the task is silently stopping after attempting to download the zip containing a version of the .NET sdk and then continues onto the next step. I would expect this to either error and fail the task or to successfully log that it has downloaded the tool and extracted into the tool directory

The offending area of code that it seems to be exiting from is in the azure-pipelines-tool-lib repository noted here - https://github.com/microsoft/azure-pipelines-tool-lib/blob/41acd733ff90c8bbc02c42376f46800b794cdc99/tool.ts#L251

We have the same issue here since this morning.

Was there a recent update to the task?
EDIT: I can see this update for this task on the release listed in the repo : #20446

[AleksuKey]

We are having this issue since this morning too.

[double-sigma]

Same issue started today morning for our .NET builds on Self-Hosted agents.

Task         : Use .NET Core
Version      : 2.246.1

[DergachevE]

Thanks for raising this issue to us.
The team will look into it and come with updates.

As per recent changes:

I can see this update for this task on the release listed in the repo : #20446
This PR introduces a new 2.246.2 task version which is not yet rolled out

[BastienPerdriau]

I rolled back to 2.243.1 which was working a few days / weeks ago and I have the same output of download not always waited without raising any error, so following tasks using dotnet are failing.
But it's a bit random, and when a task finally manage to download and extract the SDK, it can be reused on following jobs if there are on the same agent.

We also been having the same issue since this morning,

We have the same issue since yesterday:

Agent name: 'Hosted Agent'
Current agent version: '3.245.0'
Microsoft Windows Server 2022
Image: windows-2022
Version: 20240929.1.0
Downloading task: UseDotNet (2.246.1)

@JasonWhall it also happens / fails on MS Hosted, thus you could check also that box in the description:

• Microsoft Hosted

[Carike]

We have encountered the same issue on multiple pipelines and this is impacting our deliverables.

Could this please be escalated or priority elevated?

Thank you in advance

[AleksuKey]

Hi @DergachevE , could this issue be escalated? This is creating a huge impact in our dev teams unfortunately.

[tijlreynhout]

We seem to be having the same problem but it doesn't always happen for us. I have no idea why it does or doesn't work.

Agent name: 'Hosted Agent'
Current agent version: '3.245.0'
Operating System
Microsoft Windows Server 2022
10.0.20348
Datacenter

Version: 20240929.1.0

The task downloads the zip file, then finishes without extracting/installing the sdk. The next step is restoring nuget packages but this fails because the sdk version is not found.
