This Console application demonstrates the basic functionality of the Windows Live™ Contacts Representational State Transfer (REST) API.
C# Code Sample
To set up the project in Microsoft Visual Studio 2005
-
Open Microsoft Visual Studio® 2005.
-
On the File menu, click New, and then click Project. The New Project dialog box appears.
-
In the Project types pane, click Visual C#, and then click Windows.
-
In the Templates pane, click Console Application.
-
In the Name text box, type WLCDemo, and then click OK. Visual Studio 2005 creates a new project.
-
Replace the source code in the file Program.cs with the source code in the Example section for Program.cs. To do this, click Copy Code to place the code in the Windows Clipboard.
-
Open Program.cs from Solution Explorer, place your cursor anywhere in the file, and press CTRL+A.
-
Press CTRL+V to paste the code into the Visual Studio source file and overwrite the template-generated code.
-
Right-click anywhere in Solution Explorer, click Add, and then click New Item.
-
Under Templates, click XML File.
-
In the Name text box, type SamplePOST.xml, and then click Add.
-
In Solution Explorer, double-click SamplePOST.xml.
-
Replace the source code in the file with the source code in the Example section for SamplePOST.xml.
-
In Solution Explorer, right-click SamplePOST.xml, and then click Properties.
-
For the Copy to Output Directory property, click Copy Always.
-
Repeat steps 1 to 7, but replace all instances of SamplePOST.xml with SamplePUT.xml.
-
Press F5 to run the application in Debug mode.
