Concurrency error running tests in parallel

[afscrome]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I have a suite of 8 tests using DistributedApplicationTestingBuilder running in an Azure devops pipeline, and today one of these tests failed with the following error:

System.IO.IOException: The process cannot access the file 'C:\Users\AzDevOps\AppData\Local\Temp\aspire.toayd2p0.3lz\kubeconfig' because it is being used by another process.`

I do have NUnit test parallelization enabled, so I assume this is a concurrency issue. These build agents should have Windows Defender running in passive mode, so I also don't expect this to be a case of AV software interfering.

I haven't seen this error before, but today is also the first time I've started running these tests on a windows build agent, so I don't yet know if this is a rare event I was unlucky to encounter, or if this is going to be a common issue.

Expected Behavior

I expect to be able to run multiple test's in parallel.

Steps To Reproduce

Don't have exact repro steps, but I suspect this is a concurrency issue due to me running test in parallel - I believe

// nunit
[assembly: Parallelizable(ParallelScope.Fixtures)]

Exceptions (if any)
