Coverlet Experiment

Purpose

I am using Coverlet on an open source project (Lewee) and getting 0% coverage for integration tests run using Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory<T>.

I've created this repository as a more minimal replication of the issue.

My hypothesis is that problem may occur when you use an implementation of Xunit.ICollectionFixture<T> to "reset" a database before each test.
