+## Building and Running the Application
+
+Now, we can build and run the application to see the changes. Please stop the applications if they are running. Then open the *Solution Runner* panel, right-click the `CloudCrm` root item, and select the *Run* -> *Build & Start* command.

+After the applications start, you can *Browse* and navigate to the `Orders` page to see the list of orders:

+Great! We have successfully implemented the Ordering module. However, there is a problme:
+
+- We see Product's GUID ID instead of its name. This is because the *Ordering* microservice has no integration with the *Catalog* microservice and doesn't have access to Product microservice's database to perform a JOIN query.
+
+We will solve this problem in the next part by implementing an integration service between the *Ordering* and *Catalog* microservices.
+
+## Summary
+
+In this part, we implemented the Ordering module manually. We created the `Order` entity, the `OrderState` enum, the `OrderAppService` application service, and the user interface for the `Orders` page. We also added a menu item to the sidebar to navigate to the `Orders` page.
