Start by breaking up your logic into separate operations rather than trying to write everything in one line. Compilers are smart cookies so they optimize things quite well, there’s no point making your code harder to read/understand: var facultySpecialties = specialty.faculty_specialties .Where(fs => fs.faculty.active) .ToList(); // Executes the query to retrieve faculty specialties. foreach(var facultySpecialty … Read more
