Coverage Issue - New Using + Async/Await + ConfigureAwait

found during #649, this combination of code seems to have incorrect reports

        public async Task<ActionResult<IEnumerable<SystemUserItem>>> SystemUsers(CancellationToken ct)
        {
            using var data = this.factory.CreateReadOnly<SystemUserItem>();

            var list = await data.AllAsync(ct)
                .ConfigureAwait(false);

            return this.Ok(list);
        }

here is the final report output:

here is the diff of the coverage xml:

left side = unit test - code is not executed right side = integration test - code is there doesnt appear to be any branches - all code execute under a single call

Guys I found the issue…I’PR a fix asap. Are two different issue, one related to netstandard project and the other related on new async machine state code.

Adding a script that moves the files was a good call, I got it working and the problems with new using and async/await with ConfigureAwait disappeared 😃

For future reference if anyone encounters the problem, take a look at the relevant files below.

.runsettings in the root test folder (with ApodTests.csproj)

<?xml version="1.0" encoding="utf-8" ?>
<RunSettings>
  <RunConfiguration>

I’m back to 100% 😃 Thank you for the help @MarcoRossignoli!
