You are designing an update to an existing Windows Presentation Foundation (WPF) application. You plan to use Microsoft Visual Studio 2010. The updated WPF application will require a specific version of a third-party component.
You have the following requirements:
- Deploy the update by using Windows Installer. - Update the WPF application only if the required version of the third-party component is present on the client computer.
You need to recommend configuration settings for the application installer.
Which property should you recommend be set?

• A.The Version property of the Setup Project
• B.The Version property of the .NET Launch Condition
• C.The Condition property of a new Launch Condition
• D.TheRemovePreviousVersions property of the Setup Project

You are designing a .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application, a Windows service, and a private assembly shared by the WPF application and by the Windows service.
The solution stores data in a local Microsoft SQL Server Compact 3.5 database. The WPF application and Windows service will each access the database directly. The solution will be installed by using Windows Installer.
You have the following requirements:
- The installer must allow users to specify the installation folders for the WPF application and for the database. - The solution must support the deployment of updates to the WPF application without restarting the Windows service.
You need to recommend an approach for installing the solution.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

• A.Install the Windows service to the same folder as the WPF application.
• B.In the installer, create a registry key that stores the WPF application installation path.
• C.In the installer, set an environment variable that defines the database installation path.
• D.Install the Windows service to a different folder from the WPF application.

You are designing a Windows Presentation Foundation (WPF) application. The WPF application displays indicators to compare your company's past performance to the current day's operations datA.
The WPF application accesses historic data from your company's data warehouse through a Web service, and accesses current data directly from a Microsoft SQL Server 2008 database.
The WPF application must meet the following requirements:
- Retrieve historic data from the data warehouse at application startup and then
once per day.
- Retrieve current data from the database every five minutes, and then update the
indicators.
- Cache all retrieveddata.
- Target the .NET Framework 4 Client Profile.
You need to recommend an approach to data caching.
What should you recommend?

• A.UseSystem.Web.Caching with a sliding expiration.
• B.Use System.Runtime.Caching with a sliding expiration.
• C.Use System.Runtime.Caching with an absolute expiration.
• D.UseSystem.Web.Caching with an absolute expiration.

You are developing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consume a Windows Communication Foundation (WCF) service. The WCF service will provide data to the application.
You plan to use the ADO.NET Entity Framework to create a data model that will be used by the application.
Another development team makes changes to the WCF service data contract.
You need to ensure that changes made to the WCF service data contract do not require the application to be recompiled.
What should you do?

• A.Create a storage model based on the schema of the existing WCF service. Update the mapping file when the new version of the WCF service is available.
• B.Create a storage model based on the business model. Use a class generated from the storage model for programming.
• C.Create a conceptual model based on the business model. Use a class generated from the conceptual model for programming. Update the mapping file when the new version of the WCF service is available.
• D.Create a conceptual model and a storage model based on the existing version of the WCF service.

You are designing an application by using Windows Presentation Foundation (WPF) and
Microsoft .NET Framework 4.
The user interface (UI) tier of the application will be implemented in WPF.
The middle tier of the application is implemented by using an existing COM component.
The middle tier contains a long-running method named ProcessDatA.
You need to ensure that users can continue to use the UI while ProcessData is running.
What should you do?

• A.Call the Run method of the Dispatcher class before invoking ProcessDat
• B.Call the DoEvents method of the Application class before invoking ProcessDatA.
• C.Use an asynchronous worker thread to call ProcessDatA.
• D.Use the Invoke method of the Dispatcher class to call ProcessDatA.
