http://www.netfxguide.com/rss/wcf.aspxThis is the syndication feed for NetFXGuide.com - WCF.Sometimes it is necessary to create an intermediate service (or router service) is introduced, between a client and a target service to receive messages that flow between them and perform activities such as logging, priority routing, online/offline routing, load balancing, or to introduce a security boundary. Michele Leroux Bustamante shows how to do it in WCF explaining WCF addressing and message filtering concepts while focusing on the router scenario.http://www.netfxguide.com/resources/_939_building_a_wcf_router_part_1.aspx05/07/2008 21:00:22Is it possible was to support a Federation Scenario over TCP in WCF? Peolo Cibraro explains how he made it. Code sample is available for download.http://www.netfxguide.com/resources/_932_federation_over_tcp_with_wcf.aspx24/04/2008 20:22:20Aaron Skonnard shows how WCF provides numerous extensibility points that allow the developer to customize the runtime behavior for service dispatching and client proxy invocation. It is possible to tap into these extensibility points by writing custom behaviors that can be applied declaratively to the services.http://www.netfxguide.com/resources/_905_extending_wcf_with_custom_behaviors.aspx16/01/2008 16:36:11A Channel9 video showing how to use JSON in the programming model and serialization. This is one of several new features for writing non-SOAP web services.http://www.netfxguide.com/resources/_898_programming_json_with_wcf_in_net_framework_3_5.aspx31/10/2007 12:46:07In WCF, services support throttling as a way of mitigating potential DoS (denial of service) attacks. Kenny Wolf has got some useful information.http://www.netfxguide.com/resources/_877_throttling_in_wcf.aspx17/10/2007 17:43:04A concise blog post sheding some light on threading and throttling differences between WCF and web services.http://www.netfxguide.com/resources/_869_threading_and_throttling_differences_between_wcf_and_asmx.aspx15/10/2007 21:39:01A post by Kjell-Sverre Jerijærvi explaining how to achieve streaming of large data through the implementation of an upload service prototype using WCF and a HTTP binding.http://www.netfxguide.com/resources/_865_wcf_streaming_upload_files_over_http.aspx14/10/2007 06:57:59Juval Lowy, certainly an authority on WCF, has written an article on MSDN Magazine about WCF Transaction Propagation. See what Windows Communication Foundation has to offer.http://www.netfxguide.com/resources/_826_a_closer_look_at_configuring_wcf_transaction_propagation.aspx18/04/2007 18:00:54A high-level performance comparison between Windows Communication Foundation and other Microsoft .NET distributed communication technologies. Some interesting and reassuring results come out of it, e.g. WCF is 25%—50% faster than ASP.NET Web Services.http://www.netfxguide.com/resources/_816_a_performance_comparison_of_wcf_with_existing_distributed_communication_technologies.aspx05/04/2007 08:00:59A clear and short blog post explaining how to set up ClickOnce deployment of a WCF client application with Visual Studio 2005 and .NET 2 SmartClient functionality.http://www.netfxguide.com/resources/_773_clickonce_deployment_of_wcf_client_net_3.aspx19/01/2007 10:57:55
