[BUG]: MSBuild task fails after msbuild.exe exits with exit code '' (empty string) about azure-pipelines-tasks

[v-schhabra]

Hi @chrisfcarroll
Msbuild task is owned by ABTT team.
I just tagged them here. I hope they will get notify now about this issue.

This happens still,

Current agent version: '3.239.1'
...
##[error]Process 'msbuild.exe' exited with code ''.

Assuming this happens in azure-pipelines-tasks-lib (ToolFunctions.ps1):

Tasks/MSBuildV1/msbuild.ts

        Write-Verbose "Exit code: $LASTEXITCODE"
        if ($RequireExitCodeZero -and $LASTEXITCODE -ne 0) {
            Write-Error (Get-LocString -Key PSLIB_Process0ExitedWithCode1 -ArgumentList ([System.IO.Path]::GetFileName($FileName)), $LASTEXITCODE)
        }

Is $LASTEXITCODE being unset really properly handled here?

When the process fails, the last project compiled looks like this with diagnostics on:

Could this be something that only happens on self-hosted agents?

I'm using self-hosted agents, and it looks to me that OP is too.

@DenisRumyantsev , @v-schhabra : my apologies for @-ing you but it looks like this has been triaged into Azure:Artifacts by a bot, where it is receiving no attention perhaps because it is not related to artifacts ?
