Code inspection: Assignment results are fully discarded

This inspection reports an assignment or deconstruction where every assigned value is discarded. The assignment itself has no useful target, so the code either does nothing meaningful or is only keeping the right side for its side effects.

Example

                class C
                {
                    int M(int x) => x;
                    void Test()
                    {
                        (_, _) = (M(1), M(2));
                    }
                }
            

                class C
                {
                    int M(int x) => x;
                    void Test()
                    {
                        M(1);
                        M(2);
                    }
                }
            

Quick-fix

Depending on context, the quick-fix can also replace the assignment with a simpler expression or remove it.
