Hi Sunil Bindra,

Thanks for reaching out on Microsoft Q&A.

The issue with GitVersion Task 5.0 failing after uninstalling .NET Core 2.1 is a known compatibility problem because GitVersion 5.0 requires .NET Core 2.1 runtime, which is out of support.

Use the official GitVersion Azure DevOps extension tasks designed for Azure Pipelines:

• Replace GitVersion Task 5.0 with the combination of:

gittools.gitversion.setup@0

gittools.gitversion.execute@0

• These tasks are maintained independently from GitHub Actions GitVersion and do not require .NET Core 2.1.
• They support running with newer .NET SDKs (like .NET 6, 8, 10) installed on your build agent.

Ensure you have a supported .NET SDK installed on your self-hosted agents, such as .NET 6 or .NET 10, which you already installed.

steps:
- task: gittools.gitversion.setup@0
  inputs:
    versionSpec: '5.x'
- task: gittools.gitversion.execute@0
  inputs:
    useConfigFile: true
    configFilePath: 'Build/GitVersion.yml'

Do not reinstall .NET Core 2.1 since it is out of support and conflicts with company policies.

Check that your agents use the latest GitVersion CLI version (5.x or newer) compatible with the Azure DevOps extension tasks.

Optionally, you can also install GitVersion as a global tool via the .NET CLI and invoke it in scripts if preferred.

Tried gitSetup. getting belwo erro

Hi Sunil Bindra,

add your proxy’s root certificate (or the external server’s certificate) to the Windows Trusted Root Certificate Authorities on your build agent.

Restart the agent after making changes.

Resolve the self signed certificate in certificate chain by adjusting your self-hosted build agent’s certificate trust
