Azure DevOps Pipeline doesn't support .NET 7?

[marcelbeeker]

My Build Pipe line fails on the nuget restore task in Azure Devops. I set my build agent to: windows-latest

The logging of my build pipe line is as follows:

Not sure if below helps however the agents dont appear to have been updated to include dotnet core 7. This usually takes some time after releases. The following YAML should work to install the SDK.

pool:
  vmImage: ubuntu-latest

steps:
- task: UseDotNet@2
  displayName: 'Use .NET Core sdk'
  inputs:
    packageType: sdk
    version: 7.x
    installationPath: $(Agent.ToolsDirectory)/dotnet

This will then output as

PTAL @rrelyea @nkolev92

[marcelbeeker]

@Nico-VanHaaster I added the Use DotNET build step -> it's working now. Many thanks!

[RyantheLeon]

In last year's similar discussion I mentioned that it'd be nice for the pipeline to look at the version within the project instead of having to define it twice (see here: #6907 (comment)). Has any progress been made on that? It seems like it'd stop this from being a yearly issue every November when a new version is released.

[superjulius]

.Net 7 should be part of the Azure DevOps Hosted Agent (20221111.1) Windows 2022 image should be updated soon hopefully. See PR actions/runner-images#6567

As a workaround I have been using the UseDotNet@2 task, but it seems to fail more times than it works. I am curious why this wouldn't work 100% of the time.

- task: UseDotNet@2
  displayName: 'Use .NET Core sdk 7.x'
  inputs:
    version: 7.x

@paulczy probably a new issue is better but I think https://github.com/microsoft/azure-pipelines-tasks/ is the best place for this.

We've been using the same task for our pipeline without issues.

[marcelk-workstreampeople-com]

  - task: UseDotNet@2
    inputs:
      packageType: 'sdk'
      version: '7.0.x'

seems to work

[marchy]

While this does provide a workaround in the interim, it adds a good 1.5mins to all our build pipelines which has a meaningful
impact on dev process.

Any ETA on when the .NET 7 SDK will be included in Pipelines out-of-the-box?

Tracking the Azure DevOps release notes (or the Pipelines release notes specifically) there doesn't seem to have been a release since Nov 2, 2022 – before .NET 7 was officially released.

[superjulius]

@marchy It is included already as far as I can tell.

https://github.com/actions/runner-images/blob/main/images/win/Windows2022-Readme.md

[marchy]

@superjulius Fantastic, looks like it's indeed now working! 🎉

Seems like the UseDotNet@2 task is not smart enough to know to use the system version if it's already installed, so the following Pipelines task:

steps:
  # .NET
  # include the .NET SDK explicitly (NOTE: needed around version updates) 
  - task: UseDotNet@2
    inputs:
      packageType: 'sdk'
      useGlobalJson: true
    displayName: 'Use .NET SDK'

still ends up downloading a fresh version of the SDK ("Version 7.0.100 was not found in cache") even though it's a perfect match, thus we never detected the actual VM inclusion despite being on the lookout for it in our builds.

Anyways glad we're past it!

Looks like it has gone in the VM on Nov 24 (commit).

[thinkOfaNumber]

sorry to hijack this thread, but am I reading this right that I don't need to install maui workloads if I'm using windows-2022? i.e. no need to dotnet workload install android maui ... to build for framework net7.0-android?

[duaneking]

This is still an issue.

On azure pipelines I get the following:

"Error NETSDK1045: The current .NET SDK does not support targeting .NET 7.0.
