1. FT13 What’s New in WCF 4 Ed Pinto Program Manager Microsoft Corporation

2. Agenda • Improvements to things you do today • Configuration • Monitoring • New scenarios enabled • Routing • Discovery

3. Endpoint Configuration in 3.x http://host Service vdir1 vdir2 A B C vdir2 Echo.svc Web.config

4. Default Endpoints http://host ServiceHost.AddDefaultEndpoints() Service vdir1 vdir2 A B C vdir2 Echo.svc Echo.svc Protocol Mapping

5. Default Bindings <system.serviceModel> <bindings> <basicHttpBinding> <binding name=""maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"/> </basicHttpBinding> </bindings> </system.serviceModel> http://host Service vdir1 Web.config A B C vdir2 vdir2 Echo.svc Endpoint using BasicHttpBinding picks up default binding configuration from higher in the config hierarchy

6. Default Behaviors <system.serviceModel> <behaviors> <serviceBehaviors> <behavior> <serviceThrottlingmaxConcurrentCalls="32"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> http://host Web.config Service vdir1 A B C vdir2 vdir2 Bv Echo.svc A Service or Endpoint picks up default behaviors from higher in the config hierarchy Web.config

7. Default Behaviors <system.serviceModel> <behaviors> <serviceBehaviors> <behavior> <serviceMetadatahttpGetEnabled="true"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> http://host Web.config vdir1 A B C Service vdir2 vdir2 Bv Bv Echo.svc Behaviors from higher in the config hierarchy are merged with behaviors in a local config file Web.config

19. Discovery • The ability to publish a service’s endpoint metadata and discover services using well defined criteria • Design time • Find available services • Runtime • Reduced Config • Location agility • Dynamic / self healing apps • WS-Discovery – Standard interoperable discovery protocol
