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

2. You are designing a Windows Presentation Foundation (WPF) application.

D) Define aUICulture element for each language in the project file.

3. You are designing a .NET Framework 4 solution that contains a Windows Presentation Foundation (WPF) application and a Windows Communication Framework (WCF) Web service.
The WPF application will be deployed to users1 desktops located in the company's corporate network. The WCF Web service will be deployed to a Web farm located in the company's perimeter network. The firewall between the perimeter network and the Internet allows only HTTP and HTTPS traffiC.
You need to recommend an approach for minimizing the attack surface of the WCF Web service.

B) Add a load-balancing router to the Web farm configuration.
C) Set up an SSL certificate on the server.
D) Configure a WCF endpoint to use the NetTcpBinding binding.

4. You are designing a Windows Presentation Foundation (WPF) application. The application data files have the file name extension.abc.

B) ClickOnce
C) Windows Installer
D) XCopy

5. You are designing a Windows Forms application. The application connects to a Microsoft SQL Server 2008 database.
You need to recommend an approach for retrieving and logging all informational messages and error messages reported by the database.
