C# doesn't encourage usage of unsigned types and warns that they
are not CLS-compliant. You're going against established practices
there. And signed types for numbers works wonders in C# without
any notable problem and makes reasoning about code easier as you
don't have to manually check for unsigned conversion bugs
everywhere.

That's the whole point: mixing signed with unsigned is bug-prone.
Worse, it's inevitable if you force unsigned types everywhere.
