Checking for overflow has been skipped CS-W1087

checked and unchecked statements specify the behavior when an overflow occurs. In a checked context, OverflowException is thrown whereas in unchecked context, any high-order bits that cannot be accommodated by the destination type are discarded silently. Therefore, using unchecked contexts may introduce pitfalls into your codebase unknowingly and should be avoided.

Bad Practice

var sum = unchecked(list.Sum()); // `Sum()` invoked in an unchecked context

Recommended

// Alternate scenario 1
var sum = list.Sum();

// Alternate scenario 2
try
{
    var sum = checked(list.Sum());
} catch (OverflowException)
{
    // Handle this case appropriately
}
