ASP.NET Weblogs — Fri, 18 Dec 2009 16:19:00 GMT

Sender-vouches is one of the two subject confirmation methods included in the SAML security token profile specification. Essentially, the sender-vouches scenario enables an attesting entity to vouch for the identity of a subject to a relying party. The following figure illustrates this scenario: From the protocol standpoint, an attesting entity uses the sender-vouches confirmation method to assert that it is acting on behalf of the subject of SAML statements attributed with a sender-vouches SubjectConfirmation...( read more ) Read More......(read more)

Microsoft and Oracle showcase WS Interoperability at Gartner’s AADI summit

ASP.NET Weblogs — Fri, 11 Dec 2009 15:12:00 GMT

The reason is that I have been hands on working on a very ambitious project to showcase Web Services interoperability between Microsoft and Oracle platforms. This experiment allowed us to explore the interoperability of WCF 4.0 and WIF RTM with the upcoming release of Oracle WebLogic within the context of a real world application.

Getting Started with the MVVM Pattern in Silverlight Applications

ASP.NET Weblogs — Wed, 09 Dec 2009 07:30:06 GMT

With the increasing popularity of Silverlight as an application development framework the discussion of patterns has grown louder and louder. Fortunately the majority of developers building Silverlight applications have agreed on a pattern that fits well in the Silverlight world called Model-View-ViewModel (MVVM). The MVVM pattern allows applications to be divided up into separate layers that provide multiple benefits ranging from better code re-use to enhanced testing capabilities. This post will explain key concepts found in the MVVM pattern and attempt to present them in a way that is easy to understand. I’ll show some code along the way to demonstrate how the MVVM pattern can be used and provide a few alternatives when it comes to binding...(read more)

On the Arrival of Mr. Adam Mohamed Meligy…

ASP.NET Weblogs — Wed, 14 Oct 2009 00:29:28 GMT

Today (technically yesterday, since it’s 3:26 AM already while I’m starting this), Mr. Adam Mohamed Meligy finally arrived home, after staying 9.5 days in nursery. This –dear audience- given Mr. Adam arrived to our world only in October 5, 2009, a date that the entire world will (sooner or later) always remember! Mr. Adam is now taking a personal cover, pretending to be a normal baby, while he is pretty professional, he cannot sometimes hide his special natures, being relatively quiet compared to normal babies, and highly responsive to touches and (believe it or not) spoken notes/requests. These are things that the world will remember once Mr. Adam finishes his first big achievement in the field he will take up for living (God Willing). Some...(read more)
