The following code returns no results, even though this user exists in the database. using (var context = new Entities()) { var search = "testuser"; var result = context.Users .Where(u => u.UserName == search) .FirstOrDefault(); } I know I can get around this by padding the search string or by trimming the database column, but I'm looking for an alternate solution. I
