Starting with the .NET Framework version 3.5, partially trusted callers can access public types and methods implemented in System.ServiceModel, System.Runtime.Serialization, and System.ServiceModel.Web. This section describes supported scenarios for using Windows Communication Foundation (WCF) within a partially trusted application as well as the limited subset of WCF functionality available to applications running with reduced code access security (CAS) permissions.
Supported Deployment Scenarios
Describes the main partial trust scenarios for running WCF.
Partial Trust Feature Compatibility
Describes the WCF features that cannot be used with partial trust.
Partial Trust Best Practices
Contains best practices for using WCF in partially trusted applications.
