WCF/Security/BizTalk/WF/BPEL There are at least 14 distinct Security Scenarios in WCF.  It is easily the most confusing area in WCF in my experience, simply because of the many options available. If you combine that with the current industry focus out there on Identity solutions, Federation, and SAML, you have one confusing area. It is good then that P&P is addressing this area with WCF Security application as part of the patterns & practices WCF Security guidance project . Nick also has a post on this. Matzev comments on a serious limitation present in the RTM version of WCF 3.0/3.5 regarding control of WS-RM retry messages. We have encountered this as well. My distinguished colleague, Brian Loesgen , on the West Coast side of our practice has a post on two very useful new BizTalk Resources to make our lives easier BPEL support has come up quite loudly in several engagements lately. It is good to see the BPEL for Windows Workflow Foundation March CTP . Technorati Tags: WCF , Security , BizTalk , WF , BPEL Read More...
