Exercise 1: Enabling Out of Browser

The out-of-browser feature in Silverlight opens a new world of possibilities. Silverlight 4 extends out-of-browser functionality by enabling trusted applications. This makes it closer to programming for WinForms. This lab focuses on core out-of-browser functionality. To get started you must first enable your Silverlight project to run in an out-of-browser window, which this exercise outlines.

1. Open the solution for this lab, and run the project. The application will run in a browser, and you’ll notice WebBrowser control saying “HTML is enabled only in Out-of-Browser mode”.

2. To enable out of browser, stop debugging, and open the Properties page in Visual Studio. Here click the “Enable running application out of the browser”.

3. Before running the project, right click the Silverlight project and select Set as Startup Project.

4. Run the project. Your application is now running in Out-of-Browser mode. If you’re coming from WinForms you should feel at home now…no browser!
   Note:

   Notice you can see HTML, Flash, and Silverlight running inside the app!
