Code inspection: Foreach loop can be converted into LINQ-expression but another 'GetEnumerator' method will be used

This inspection reports a yield return over another sequence that can be rewritten as a foreach. The fix replaces a query-style yield with an explicit foreach that enumerates the source and yields each element.

Example

                public IEnumerable<int> GetSequence()
                {
                    var ints = new int[10];
                    yield return ints;
                }
            

                public IEnumerable<int> GetSequence()
                {
                    var ints = new int[10];
                    foreach (var i in ints)
                        yield return i;
                }
            

Quick-fix

Convert the sequence-producing statement into an explicit foreach loop.
