Code inspection: Return of a task produced by 'using'-captured object

This inspection reports returning a task that was created from an object declared in a using scope. The object can be disposed before the returned task finishes using it.

Example

                using System.IO;
                using System.Threading.Tasks;
                Task<string> ReadAsync(string path)
                {
                    using var reader = File.OpenText(path);
                    return reader.ReadToEndAsync();
                }
            

                using System.IO;
                using System.Threading.Tasks;
                async Task<string> ReadAsync(string path)
                {
                    using var reader = File.OpenText(path);
                    return await reader.ReadToEndAsync();
                }
