This sample demonstrates a WPF (Windows Presentaion Foundation) Application communicating with the WCF service exposed by a DomainService. The application does an AddServiceReference to the WCF DomainService to get a ServiceReferenceClient. It then queries the service for data, as well as makes updates to the data model.
The sample also shows has a Silverlight head working against the same Domain Service.
For a step by step guide on how to build the HRApplication click here - https://code.msdn.microsoft.com/Release/ProjectReleases.aspx?ProjectName=RiaServices&ReleaseId=2387
To run the application, just copy the AdventureWorks database to the App_Data Folder.
You can download the Database from here - http://www.codeplex.com/MSFTDBProdSamples/Release/ProjectReleases.aspx?ReleaseId=4004
NOTE - If the DataBase is not present the WPF application will fail with the error:
System.Windows.Markup.XamlParseException was unhandled
'The invocation of the constructor on type 'WpfHRApp.MainWindow' that matches the specified binding constraints threw an exception.
The WPF application in the sample has a ServiceReference to the WCF Service exposed by the RIA Services Domain Service @ http://localhost:XXXXX/HRApp-Web-OrganizationService.svc
The Application then queries form Employee Data from the WCF service and displays it in a DataGrid. The Application also provides a button which allows users to 'File a Sick Day' i.e. subtract 12 hours from the selcted users SickLeaveHours.
In the OrganizationService.metadata.cs file there is a Rule defined that SickLeavehours cannot be less than 12 or greater than 200.
public short SickLeaveHours;
Hence if the SickLeaveHours are reduced below 12, a validation exception is thrown.
Microsoft WCF RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms using WCF. The RIA Services provides a prescriptive pattern to write application logic that runs on the mid-tier and controls access to data for queries, changes and custom operations. It also provides end-to-end support for common tasks such as data validation, authentication and roles by integrating with Silverlight components on the client and ASP.NET on the mid-tier. It includes rich tooling for integrating client and mid-tier projects and for building rich UI through the simplicity of drag-drop support.
