Dotnet Publish crashes with error 'MSB4166: Child node "##" exited prematurely. Shutting down.'

Can also confirm that adding the ENV variable (DOTNET_CLI_TELEMETRY_OPTOUT: 1) to the github action fixed the issue

This is a dotnet SDK regression - we will have a 401 hotfix SDK out in the next day or so that fixes this. In the meantime the most consistent workaround is using the latest 30x SDK instead. Details about the issue can be found at dotnet/sdk#42719 (comment).

The 8.0.401 hotfix SDK has been released on all channels and contains a fix for this issue.

Since this appears to be happening from telemetry, try setting the DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1.

We're getting this exception on some of our self-hosted runners, but not all. It seems to only happen with SDK 8.0.400 but not 8.0.304; try using a global.json to explicitly use the older SDK:

{
  "sdk": {
    "version": "8.0.304"
  }
}

(That is, I suspect it's an issue in the SDK, not in https://github.com/actions/runner.)

This happens in Azure Devops with self-hosted agents as well. Agent version 2.206.1 running Linux

Update: Setting the environment resolves the issue

Update2: Other applications can build and published using 8.0.400 on the very same agent..

Getting the same issue, looks like something broke today. Github action is failing whilst building a .net 8.0 C# project....

This started happening for me as well

Apparently the same regression has been introduced in .NET 9 preview (9.0.100-preview.7.24407.12) which is now installed with the latest VS, because even after installing 8.0.401 whenever I'm trying to run azd deploy MyService it fails with the error above. When running azd deploy with --debug flag I can see that it appears to be using the latest available .NET version which in my case is the .NET 9 preview. The only way how I could make it work (setting DOTNET_CLI_TELEMETRY_OPTOUT to 1 did nothing) is to add in the root folder of my solution "global.json" with this content:

{
    "sdk": {
        "version": "8.0.401"
    }
}
