Topic 5, ASP.NET MVC

 

Background

You are developing an ASP.NET MVC application in Visual Studio 2012 that will be used to process orders.

 

Business Requirements

The application contains the following three pages:

 

clip_image002A page that queries an external database for orders that are ready to be processed. The user can then process the order.

clip_image002[1]A page to view processed orders.

clip_image002[2]A page to view vendor information.

 

The application consumes three WCF services to retrieve external data.

 

Technical Requirements

Visual Studio Solution

The solution contains the following four projects.

ExternalQueue: A WCF service project used to communicate with the external order database.

OrderProcessor: An ASP.NET MVC project used for order processing and logging order metadata.

OrderUpload: A WCF service project used to submit order data to an external data source.

Shipping: A WCF service project used to acquire shipping information.

 

ExternalQueue Project

Entity Framework is used for data access. The entities are defined in the ExternalOrders.edmx file as shown in the following diagram.

 

clip_image004

The project contains two services defined in the following files.

 

clip_image002[3]IExternalQueueService.es

clip_image002[4]ExternalQueueService.svc

 

The ExternalQueue.Helpers namespace contains a definition for a class named OrderNotFound Exception.

 

OrderProcessor Project

Entity Framework is used for data access. The entities are defined in the ProcessedOrders.edmx file as shown in the following diagram.

 

clip_image006

 

The classes are contained in the OrderProcessor.Entities namespace. The project contains the following two controllers.

 

clip_image002[5]InboundQueueController.es

clip_image002[6]ProcessedOrderController.es

 

WCF service proxies to the ExternalQueue, Shipping and OrderUpload services have been generated by using the command prompt. The ExecuteCommandProcedure() method in the ExternalQueueService.svc file must run asynchronously.

 

The ProcessedOrderController controller has the following requirements. The GetVendorPolicy() method must enforce a 10 minute absolute cache expiration policy. The GetProcessedOrders() method must return a view of the 10 most recently processed orders.

 

OrderUpload Project

The project contains two services defined in the following files:

 

clip_image002[7]IUploadCallbackService.es

clip_image002[8]UploadCallbackService.svc

 

Data Access is maintained in a file named UploadOrder.es.

 

Shipping Project

Entity Framework is used for data access. The entities are defined in the ExternalOrders.edmx file as shown in the following diagram.

 

clip_image008

 

The Custom Tool property for ExternalOrders.edmx has been removed.

 

POCO classes for the Entity Model are located in the ShippingAddress.es file. The POCO entity must be loaded by using lazy loading.

 

The project contains two services defined in the following files.

 

clip_image002[9]IShippingService.es

clip_image002[10]ShippingService.svc

 

The IShippingService contract must contain an operation that receives an order number as a parameter. The operation must return a class named ShippingInfo that inherits from a class named State.
