Como: Configure Visual Studio to Debug a XAML Browser Application to Call a Web Service

aplicativos de navegador XAML (XBAPs) run within a partial-trust security sandbox that is restricted to the Internet zone set of permissions. This permission set restricts Web service calls to only Web services that are located at the XBAP application's site of origin. When an XBAP is debugged from Microsoft Visual Studio 2005, though, it is not considered to have the same site of origin as the Web service it references. This causes security exceptions to be raised when the XBAP attempts to call the Web service. However, a Microsoft Visual Studio 2005 Aplicativo de Navegador XAML (WPF) project can be configured to simulate having the same site of origin as the Web service it calls while debugging. This allows the XBAP to safely call the Web service without causing security exceptions.

Configuring Visual Studio

To configure Microsoft Visual Studio 2005 to debug an XBAP that calls a Web service:

1. Configure Microsoft Visual Studio 2005 to debug XBAPs (see Como: Configurar o Visual Studio para depurar um aplicativo de navegação XAML).

2. Com um projeto selecionado no Solution Explorer, no menu Project, clique em Properties.

3. In the Project Designer, click the Debug tab.

4. In the Start Options section, add the following command-line parameter to the Command line arguments text box:

   -debugSecurityZoneURL URL

   The URL value for the -debugSecurityZoneURL parameter is the URL for the location that you want to simulate as being the site of origin of your application.

As an example, consider a aplicativo de navegador XAML (XBAP) that uses a Web service with the following URL:

http://services.msdn.microsoft.com/ContentServices/ContentService.asmx

The site of origin URL for this Web service is:

http://services.msdn.microsoft.com

Consequently, the complete -debugSecurityZoneURL command-line parameter and value is:

-debugSecurityZoneURL http://services.msdn.microsoft.com
