Code inspection: Redundant explicit nullable type creation

This inspection reports an explicit nullable value creation such as new int?(value) when the value can be used directly. The explicit new Nullable<T>(...) form is usually redundant in ordinary C# code.

Example

                class C
                {
                    int? GetValue()
                    {
                        return new int?(10);
                    }
                }
            

                class C
                {
                    int? GetValue()
                    {
                        return 10;
                    }
                }
