Nullability of reference types in type of parameter 'objIsNotNull' of 'void StackCalculator.Assert(object objIsNotNull, string message)' doesn't match implicitly implemented member 'void IWasmValidationContext.Assert(object? objIsNotNull, string message)' (possibly because of nullability attributes).

Introducing a 'Finalize' method can interfere with destructor invocation. Did you intend to declare a destructor?

Possible null reference return.

Non-nullable field 'Label' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable field 'TopLabel' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Dereference of a possibly null reference.

Dereference of a possibly null reference.

Non-nullable field 'Block' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable field 'Body' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.
