قسمت دوم اضافه کردنIdentity به پروژه MVC

قسمت دوم از مطلب مربوط به استفاده از Identity  در MVC (قسمت اول)

حال نوبیت به ساخت Controller  های مرتبط به مدیریت User  و مدیریت Role  میپردازیم

در پوشه Controlle  مربوط به پروژه  کنترل هایی با نام RolesAdminController و UserAdminController بسازید و محتویات آنها را به صورت زیر تغییر دهید، البته میتوانید با توجه به نیاز خود آنها را تغییر دهید.
