• در مثال قبل پروژه به صورت Desktop و با WPF پیاده سازی شده بود ولی در این مثال با Silverlight می‌باشد؛
• در مثال قبل از UnityBootstrapper استفاده شده بود ولی در این مثال از MefBootstrapper؛
• در مثال قبل هر View در یک ماژول قرار داشت ولی در این مثال هر دو View را در یک ماژول قرار دادم؛
• در مثال قبل از Prism Libary 2.x استفاده شده بود ولی در این مثال از PrismLibrary 4.x؛
• و...

نکته : برای فهم بهتر مفاهیم، آشنایی اولیه با MEF و مفاهیمی نظیر Export و Import و AggregateCatalog و AssemblyCatalog نیاز است. در صورتی که با این مطالب آشنایی ندارید می‌توانید از (^) شروع کنید.
