• نوع خروجی تابع باید از <IQueryable<T  باشد. T باید از جنسی باشد که معادل EDM آن موجود باشد. T می‌تواند از انواع اصلی (Primitive) باشد که در EF پشتیبانی می‌شوند (رجوع شود به  Entity Data Model: Primitive Data Types   )به طور مثال، int قابل استفاده است ولی uint خیر و یا می‌تواند از انواع غیر اصلی (  non-primitive ) باشند (enum/complex type/entity type ) که در مدل شما تعریف شده‌اند.
• پارامترهای متد باید از نوع اسکالر (primitive یا enum) باشند که قابل map شدن به نوع‌های EF باشند.
  
• نام متد،  DbFunction.FunctionName   و querystring ایی که به CreateQuery  پاس داده می‌شود باید همگی یکسان باشند.
