Do not use a Where clause to filter before calling Assert.Single. Use the overload of Assert.Single that accepts a filtering function. (https://xunit.net/xunit.analyzers/rules/xUnit2031)

Do not use Assert.NotEmpty to check if a value exists in a collection. Use Assert.Contains instead. (https://xunit.net/xunit.analyzers/rules/xUnit2030)

Test methods should not use blocking task operations, as they can cause deadlocks. Use an async test method and await instead. (https://xunit.net/xunit.analyzers/rules/xUnit1031)
