Hi everyone,

As you all know that we announced Visual Studio 2011 and the next framework version v4.5 at BUILD conference last week.

Please note that we are using the combined forum here - https://forums.asp.net/1239.aspx/1?ASP+NET+4+5+Developer+Preview+and+Visual+Studio+11+Developer+Preview for answering all WCF v4.5 preview related questions. Please post all such questions there to get quick set of eyes.

WCF v4.5 feature list:

Here is a quick list of features/enhancements we are bringing in WCF v4.5, your feedback is welcome. I will be blogging about these in detail in the next few days.

Scalable modern communication stack

- Scalable, bi-directional communication over HTTP using WebSockets

- Interoperable public UDP multi-cast channel

- TCP support for high-density scenarios (partial trust)

- Support for Tasks and the new C# Async language features throughout WCF programming model

- Improved streaming support

- Compression support (gzip/deflate) for binary encoding

Continued commitment to simplicity

- Further config simplification, config intellisense, making WCF throttles/quotas smarter & work for you by default!

- Support for multiple authentication modes on a single WCF endpoint

- Better manageability via rich ETW & e2e tracing

- XSD-first type authoring experience

- Support for Internationalized Domain Name (IDN) WCF services.

Win8

Support for WCF client in Win8 immersive applications with basicHttp/netTcp/WebSocket* bindings.

[*WebSocket support for Win8 WCF Immersive apps is not present in the current preview release but we are working to add it in the final 4.5 release]
