1. توسعه پایگاه داده سیستم دسترسی مبتنی بر نقش
2. توسعه یک Customized Filter Attribute بر پایه Authorize Attribute
3. توسعه سرویس‌های مورد استفاده در Authorize Attribute
4. توسعه کنترلر Permissions: تمامی APIهایی که در جهت همگام سازی دسترسی‌ها بین کلاینت و سرور را بر عهده دارند در این کنترلر توسعه داده میشود.
5. توسعه سرویس مدیریت دسترسی در کلاینت توسط AngularJS

جادوی پشت صحنه

مقادیر پراپرتی‌ها در کلاسی استاتیک به اسم Dependency Property ذخیره می‌شوند که این ذخیره در حالت نام و مقدار است و مقدار آن شامل callback و مقدار پیش فرض است. شکل زیر نتیجه‌ی شکل دقیق‌تری را نسبت به قبلی در هنگام پیمایش درخت منطقی به سمت بالا، نشان می‌دهد.

نحوه‌ی تعریف یک خاصیت وابسته که باید به صورت ایستا تعریف شود به صورت زیر است و برای دریافت و درج مقدار جدید از یک پراپرتی معمولی کمک می‌گیریم:

// Dependency Property
public static readonly DependencyProperty CurrentTimeProperty = 
     DependencyProperty.Register( "CurrentTime", typeof(DateTime),
     typeof(MyClockControl), new FrameworkPropertyMetadata(DateTime.Now));
 
// .NET Property wrapper
public DateTime CurrentTime
{
    get { return (DateTime)GetValue(CurrentTimeProperty); }
    set { SetValue(CurrentTimeProperty, value); }
}
