ضمن اینکه اگر کسی بخواهد کار جدی اعتبارسنجی را در Web API انجام دهد بهتر است از Fluent Validation استفاده کند (که تبدیل به یک استاندارد برای آن شده‌است).

• ابتدا باید نام و مکان هر ماژول رو به Prism معرفی کنیم که می‌تونیم اون‌ها رو در کد یا Xaml یا Configuration File تعریف کنیم.
• با استفاده از Metadata باید وابستگی‌ها و مقادیر اولیه برای هر ماژول مشخص شود.
• با کمک تزریق وابستگی‌ها ارتباطات بین ماژول‌ها میسر می‌شود.
• ماژول مورد نظر به دو صورت OnDemand و Available  لود خواهد شد.
