The build warnings were of these type (mostly reported by xUnit's Code Analyzers):
- Fixed wrong parameter order in xUnit assertions (can lead to poor error reporting in test failures)
- Unused code was removed
- Correct assertions were used (e.g. Assert.True/.Contains/.EndsWith)
- Public non-test methods on test classes were made private
