Coverage fall suggests not all of these are strictly correct and change the semantics.

Actually, might just be a flaky test.

Pull Request Overview

This PR applies AD0001 and AD0002 code fixes to simplify the codebase by removing unnecessary generic type parameters from method calls where the compiler can infer the types automatically.

• Removed redundant generic type parameters from various method calls across test and source files
• Simplified XML documentation references by removing fully qualified namespaces where unnecessary
• Updated one test method to use CancellationToken.None instead of the fully qualified version
