Uhm. Build still red. Any action needed on my part?

[josteink]

From the build:

/home/vsts/work/1/s/src/coverlet.console/ConsoleTables/ConsoleTable.cs(1,1): error IDE0073: A source file contains a header that does not match the required text [/home/vsts/work/1/s/src/coverlet.msbuild.tasks/coverlet.msbuild.tasks.csproj]

This is clearly not an error in my pull-request after all? :smile:

Edit: It clearly was.

"Clearly not" ahem

Looking into the errors, and validating on git master, I could see the problem was exclusively present on my branch.

I've fixed 2 nullability-related issues (which was probably always there) in a couple of tests and it builds and tests cleanly on my machine now :smile:

[josteink]

Build now succeeds, but 1 test now fails in CI (while not locally), and I don't have access to view what test failed or how it failed.

Help? :)
