Remarks

Internet Explorer 7 for Windows Vista introduced a Protected Mode setting that provides additional security. By default, Protected Mode is enabled for the Internet and Restricted Sites security zones, and disabled otherwise.

Normally, Silverlight-based applications from zones with different Protected Mode settings cannot communicate through local messaging. However, you can bypass this restriction by setting DisableSenderTrustCheck to true. This is typically necessary, for example, to enable local messaging between out-of-browser and Internet-based Silverlight applications.

For more information, see Communication Between Local Silverlight-Based Applications.
