What’s new in WCF 4.0: brief summary

Below are the notes I took at the PDC about what’s new in WCF 4.0.

Default bindings can be created. If no bindings are specified for a service, these bindings are used.
WCf supports configuration inheritance, so bindings could also be specified at various levels including the machine.config.
Same applies to behaviors
Default bindings/behaviors are the bindings/behaviors that have no name or name=”” in the configuration
Configuration based activation allows services without *.svc files
ETW (Event Tracing for Windows) is used by WCF
AppFabric (FKA “Dublin”) stores that data in a Sql Server database for easy retrieval and querying.
Routing is a completely new feature in WCF which allows service aggregation, protocol bridging and versioning.
MessageFilters are used to determine destination(s).
Routing table can be changed at runtime.
Security can also be bridged.
Alternate endpoints can be specified for fail-over-safety.
Discovery is another new feature. It allows for location agility, dynamic / self-healing apps
Discovery adheres to WS-Discovery standards
Two mode for discovery: Ad-hoc and managed
Ad-hoc discovery uses broadcasts
Managed discovery is like UDDI with a Discovery Proxy.
