dotnet publish fails with --output Cannot create/move a file when that file already exists

Describe the bug

We have an Azure Function solution and we use TeamCity to publish and pack. The publish step is using .NET runner with the following running log: Starting: .NET SDK 6.0.400 “C:\Program Files\dotnet\dotnet.exe” publish “E:\TC\work\fbe36accd285e2ac\Azure Functions\PubAzureFunctions\PubAzureFunctions.sln” --configuration Release --runtime win-x64 --output ./OutputFolder @E:\TC\temp\agentTmp\2.rsp -p:PublishReadyToRun=true --self-contained true

When TeamCity run dotent publish and passing –output it fails 2 times out of 5 with error: “C:\Temp.nuget\packages\microsoft.net.sdk.functions\4.1.2\build\Microsoft.NET.Sdk.Functions.Publish.targets(144,5): error MSB3677: Unable to move file “E:\TC\work\fbe36accd285e2ac\OutputFolder\api-ms-win-crt-time-l1-1-0.dll” to “E:\TC\work\fbe36accd285e2ac\OutputFolder\bin\api-ms-win-crt-time-l1-1-0.dll”. Cannot create a file when that file already exists.”

When I ran the same command locally I got many warnings of the same issue: C:\Program Files\dotnet\sdk\7.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Publish.targets(254,5): warning MSB3026: Could not copy “C:\Users*.nuget\packages\microsoft.netcore.app.runtime.win-x64\6.0.11\runtimes\win-x64\native\mscorrc.dll" to “D:\Repos\IntegrationPlatform\Azure Functions\PubAzureFunctions\OutputFolder\mscorrc.dll”.

@baronfel has uncovered an issue and working with the azure functions team to see what fixes they need to make. I’m sorry for assuming this was the same issue earlier. I was wrong. That was not the case, and some changes need to be made from the azure functions end most likely. @EngSayed Not your fault you are experiencing this.

[EngSayed]

The status is the same as what @baronfel mentioned earlier. We suggest you publish each project individually. As for @EngSayed’s comment: It can be a single application, but based on your output you’re still publishing a solution. I assume the solution has more than one project. If there is more than one project and you point to 1 flat output folder, then the artifacts and .dlls can conflict with one another while they publish/build/etc in parallel. It may be down the pipeline to fix this eventually but it will require significant amounts of code to be re-written.

I already mentioned many times that I have only 1 application which i am trying to publish. This is very obviously a bug which you guys are ignoring and it makes our life hard.
