Windows Phone 7 AppTo Show "Hello World" on Screen


The Windows Phone 7 SDK prerequisites are as in the following:

  • It is supported by operating systems like Windows 7 and Windows Vista with Service Pack 2
  • It requires free disk space for installation on the system drive
  • It requires a minimum of 3GB of RAM on the system

The Windows Phone Emulator requires a DirectX 10 or above.

It is compatible with versions of Visual Studio 2010 with Service Pack 1.

The Windows Phone SDK includes the following:

  • It is available in Windows Phone Emulator.
  • It is available in Windows Phone SDK 7.1 Assemblies
  • It is available in Sliverlight 4 SDK and DRT.
  • It is available in WCF Data Services Client for Windows Phone and so and so.

Note: SDK is nothing, it is a Software Development Kit.

We will now create a new project for Windows Phone using Visual Studio 2010 as in the following procedure:

  • Open Visual Studio 2010 and select "File" -> "New" -> "Project..."
  • Then, the New Project Window will appear as in the following:


  • Then Select Sliverlight for Windows Phone -> Windows Phone Application
  • Then enter the Name and Location and click the OK Button
  • Then, the New Windows Phone Application window will appear
  • Select the target Windows Phone OS Version like Windows Phone OS 7.1 in the dropdown box. Then, click the OK Button
  • Then, the HelloWorldApps project has been successfully created.


Now, I have changed the page title to Hello World in the HelloWorldApps project.

Once the program was successfully executed and deployed on the Windows Phone emulator then the output is as in the following:
