Cross-domain file for self-hosted TCP services

With the new transport (TCP) added in SL4, and a few people started asking how to serve the cross-domain policy file if the TCP service is self-hosted (like the same issue for cross-domain calls to self-hosted HTTP services). I published a new post to address this issue, again just using the web programming model capabilities of WCF (NetFX 3.5).

  2. @Ahobul – find out what is the base address for your service. If it is something like net.tcp://foo:4502/bar/service.svc, then you Carlos' self-host sample to host a policy file over http://foo/clientaccesspolicy.xml
