MSDN just published the latest version of David Chappell's paper on the uber story of identity for .NET applications (and beyond, I would add). Recommended!!! With his usual clarity David manages to capture the overall picture and provide a general frame of reference for the base concepts such as tokens, claims, identity providers, token sources & friends. Another great merit of the paper is that it puts in context many technologies and products, giving useful indications about canonical scenarios. I actually admire (& envy!) David 's ability of understanding what is the level of detail that must be provided for 1) making justice to the topic while at the same time 2) not making things too difficult for the reader. I have yet to free myself from the assumption that the reader has to dive deep for truly understanding , but I'm being told I'm slowly getting better :-) While the the paper was being written Nigel and I had a number of interesting discussions with David : I remember especially well the one about the nature of claims and the generalizations behind the idea of token source. Sometimes we got really passionate :-) Both Nigel and David are sophisticated conversation buddies and tremendously knowledgeable in the subject: I really had a pleasant time. I am very happy to recognize traces of those conversations in the text, both when it appears that he eventually agreed but also when it's clear that he was not convinced and remained faithful with his original ideas Read More...

Another episode of Italia 9 , our channel9 show featuring Italians working in the Redmond campus. Questa volta Alessandro "Cato" Catorcini ci parla di Common Language Runtime, Silverlight e applicationi ad alta affidabilita'. Enjoy the video from here ! As always special thanks to Charles "Carlo" Torre , without whom this show would simply not be possible. From Channel9's caption: Passate le vacanze, ecco puntuale la seconda puntata di Italia 9 ! Questa volta Vittorio e’ andato a trovare Alessandro Catorcini, un altro genovese che fa il senior program manager nel common language runtime team. Dopo la chiacchierata di rito sul come sia finito a lavorare in America per Microsoft, Alessandro parla a ruota libera del CLR: si va dal positioning di Silverlight all’hosting del common language runtime in applicazioni ad altissima affidabilita’ come SQL Server. Durante la discussione Alessandro cita un paper sull’hosting che puo’ essere scaricato da qui ; fa inoltre frequente menzione del blog CLR Inside Out, disponibilie da qui . Come di consueto, Alessandro terra’ d’occhio i commenti al video: se avete domande non esitate a premere “Reply”. Arrivederci alla prossima puntata! And the English version, below: Italia 9: Alessandro Catorcini and .NET Framework Reliability Now that vacation time is gone, here there’s the second episode of Italia 9 ! This time Vittorio went to visit Alessandro Catorcini, another guy from Genova who works as Senior Program manager in the common language runtime Read More...

In short: I discuss Sidebar Gadgets, and I show you how to invoke a CardSpace-protected WCF service from a simple Gadget. Full source code is provided, along with detailed commentary on the road I've followed for getting there. Added bonus: the code shows how to apply an arbitrary configuration file to WCF, an issue often encountered when hosting WCF code in processes you don't control. Sidebar Gadgets are mini applications which live in the Sidebar, a UI element on the Windows Vista desktop. They are extremely handy for keeping an eye on information you are often interested to; they are also very good at providing you a quick-reach UI for tasks you perform often. As you know I wear the server guy hat, so I'm not really the best person for explaining the advanteges of Gadget: I would suggest visiting Michael and Jaime blogs if you want more details on the subject. When I thought of how the gadget model could be useful for me, I realized that much of the information I'd like to keep an eye on happens to be confidential (like being notified if I received a wire transfer, or getting the access statistics from my website); the actions I want to take when I react to changes in those data are also requiring high security levels (like accessing a portion of my home banking for giving approval for a certain utility bill to be paid). So, would not be great if we could use CardSpace for authenticating the services accessed by a Gadget? I thought for few nights about the issue, devised a Read More...

You asked for it, we made it :-) I'm just back from vacation, and on the first day or work 1) we released the July CTP of the .NET Framework 3.0 , in which CardSpace bits work beautifully and 2) the NetFx3 community website opened a sandbox where you can experiment with your selfissued information cards. If FY07 is going to be that packed with goodness, I look forward to see what's next! ;-) Read More...

I was sentimentally attached to the name "Infocard", as I was to "Indigo" and "Avalon"... but I've to say that I love the name CardSpace! The acronym (WCS) sounds even familiar, now that I have learned to pronounce all those W-consonant-consonant. [:)] Check out the announcement of the new name on Somasegar blog . Ah, I was almost forgetting (just kidding of course): the entire WinFx has changed name, and from now on it will be known as the .NET Framework 3.0. Read More...
