Here, she tells us about background GC for server-side .NET applications and services and also touches on improvements in large heap management, generally in the next release of .NET.

In the next release of .NET (4.5), managed server applications and services will reap the benefits of background collections. This is a feature the CLR team is excited about and for good reason. It means less pausing, better overall performance. In the 4.0 release, the client CLR supported background GC. You learned about that here (from Maoni). Moving this feature to the cloud (well, to the server-side) means more performance and less pausing for ASP.NET applications, for example. This is great news.

Tune in. Enjoy.

How does GC, work, generally? Why is it important? The GC inside of the CLR is of a specfic type - ephemeral, concurrent (the server version has always been concuurent and now with Background GC on the client in CLR 4, GC is concurrent on the client as well, but there are differences...). 

Patrick takes us through the basics of GC up to the current state of the art in this outstanding conversation with one of the fathers of .NET. Of course, given the other expert in the room - programming language designer Erik Meijer, we have to talk about the impact that dynamic and functional languages have on the design of general purpose GCs as well as future directions of the CLR's GC, generally. What's Patrick working on these days? 

Patrick will be presenting at PDC09 in the the Technical Leaders track. His talk, Future of GC, should not be missed. This conversation is a great introduction to what Patrick will be talking about and we highly recommend you watch this before you attend his session (or watch his session after the show shortly after the PDC ends - like last year, all sessions will be available on-demand...).

Immo is from Germany where he is working on his Masters degree in computer science. What better team to intern with than the CLR team? What better problem to spend the summer investigating than how to make the Native Image Generator (Ngen) a more granular "service" and without requiring admin rights to create native images?

Imagine a world where NGen would run when it needed to (in addition to what it does today as part of an application installation process), automatically, and target specific and isolated pieces of the application(binaries that require re-Ngen'ing). Make sense? No? Well, Immo is a very articulate young man, so let him explain it to you. Great thinking, Immo. Looking forward to watching what happens here as NGen evolves.

How does this work, exactly? Does this mean that PIAs are no longer required? How does versioning in this scenario work, exactly?

One of the things that Vance is thinking about with respect to type inheritance is what he calls default interfaces: they are contractual, but with default implementation characteristics, as opposed to purely abstract as interfaces are today. So, a default(implementation) interface is capabe of changing without breaking the systems that implement it. Wait a minute, that' goes against the basic rules of interfaces in the OO world.

Expression 3 also ships today in Preview form. Grab the bits and play. Provide feedback. OK. That's the housekeeping stuff. Now, on to this conversation with Scott. We talk about many things in this interview and weave the deeply technical view on Silverlight 3 with more surface level perspectives. So, if you're looking for bite size marketing messages, this video isn't for you Smiley

What are the significant changes/improvements/inventions in Silverlight 3? Silverlight 2 brought the world a cross platfrom CLR. How has the CLR changed in Silverlight 3? Silverlight 3 enables Silverlight to run outside the context of a browser. What does this mean, exactly? Silverlight and Many-Core? What has the significant real world feedback been like regarding Silverlight 2 and how has it helped shape Silverlight 3? How do you work with the Moonlight folks, exactly (see Miguel's perspective on this as well)? And much, much more. This is a typically long Charles interview and we travel around The Gu's globe of knowledge (which is vast - he's an engineer at heart).

Thank you, Scott, for spending so much of your valuable time for a Channel 9 interview that should prove most interesting to many folks who watch and listen.

Erik Meijer, Expert to Expert host, programming language designer and occasionally-radical category theoritician, has spent many years working with Anders and the C# team. As you may know, Erik has been a key contributor to the addition of functional constructs to C#. 

Here, Erik and Anders wax on topics ranging from the design of C# 4.0's dynamic keyword (what's the thinking behind the thinking) to the potential near and far future of the C# language (and general purpose imperative programming, generally). Anders also spends some time at the whiteboard explaining C# 4.0's support for covariance and contravariance. Of course, we can't forget about concurrency and parallelism, so we don't.

As you might expect, the conversation takes some interesting jaunts into various programming language design rabbit holes. For example, Anders discusses the notion of creating a new language to support new problem domains versus extending current languages to meet the needs of developers who need to express solutions to complex problems (so, how do you make a language like C# more dynamic in the sense that it can readily help developers solve problems that the language was not initially designed to solve?). We talk about the work being done on a service-oriented C# compiler (compiler as a service), C# as an ESDL container (or as an EDSL itself to be hosted in other environments...) and much more. This is a fantastic conversation with some of Microsoft's true visionaries.

This is made possible with a new managed virtual machine called the Dynamic Language Runtime (DLR). The DLR runs on top of the CLR, but you can think of the DLR as it's own managed runtime (or virtual machine). For this interview, it is assumed that you have working knowledge of what the CLR does.

This interview focuses deeply on one core question: How does the DLR work. Of course, we talk about the history and future of the DLR, but primarily we find out about DLR nuts and bolts and architecure.

This interview is whiteboard heavy and compelling. It was really fun to chat with John and Martin and geek out on the DLR. It is a great technology with a very bright future.

Charles Nutter is a lead developer on the JRuby project which aims to run Ruby "natively' on the JVM. Wayne Kelly is the lead developer on the now defunct Ruby.NET project (it's been merged into the IronRuby project so Wayne and team's great work has not gone with the wind...) which aimed to get Ruby to run on the CLR.

Both Charles and Wayne are challanged by the same technical hurdles: Running dynamic code in a statically-typed environment with no support for continuations. This is really challenging and is the primary reason that Microsoft created the DLR...

Here, we chat about that they're working on and what problems they face.

Dave Thomas is well known for his work in object oriented programming language design, dynamic language development (SmallTalk), virtual machines and in the development of the Eclipse IDE.


I was lucky enough to grab Dave and Channel 9 celebrity, co-creator of LINQ and programming language scientist Erik Meijer to about objects, OO, functional programming, the future of programming languages in the age of parallelism and concurrency (multi/many-core
hardware "revolution"). We also talk about virtual machines in the context of language runtimes. Dave provides some feedback on Microsoft's approach to "managed" runtimes (aka CLR). He has an "interesting" perspectives in this area, though I don't agree with
him fully Smiley

This is a fantastic conversation with two of the computing industry's best and brightest. It was a real honor to meet Dave Thomas. He's incredibly nice and really humble given his myriad of technical accomplishments.

PFX makes it easier for developers to write programs that take advantage of parallel hardware (you've all heard of multi-core and what the future holds with many-core...), without having to deal with the complexities of threads and locks in today’s concurrent programming story. Of course, PFX is not a concurrent programming silver bullet. There is still a great deal of work left to do in the imperative programming world's approach to concurrency. PFX is an excellent start with a syntax that .NET developers can relate to and understand.

Here, Joe Duffy, Senior Software Engineer, and Technical Fellow Anders Hejlsberg sit down with me to discuss the basics and some of the details of the managed PFX library's architecture and implementation, whiteboard included.

PFX is an excellent start with a syntax that .NET developers can relate to and understand.Here, Joe Duffy, Senior Software Engineer, and Technical Fellow Anders Hejlsberg sit down with me to discuss the basics and some of the details of the managed PFX library's architecture and implementation, whiteboard included.For more information on specific technologies, check out the PLINQ and TPL articles in the October 2007 issue of MSDN Magazine.High res video download file here. 2048 http://channel9.msdn.com/Shows/Going+Deep/Programming-in-the-Age-of-Concurrency-Anders-Hejlsberg-and-Joe-Duffy-Concurrent-Programming-with Fri, 12 Oct 2007 17:21:00 GMT http://channel9.msdn.com/Shows/Going+Deep/Programming-in-the-Age-of-Concurrency-Anders-Hejlsberg-and-Joe-Duffy-Concurrent-Programming-with Charles Charles 30 http://channel9.msdn.com/Shows/Going+Deep/Programming-in-the-Age-of-Concurrency-Anders-Hejlsberg-and-Joe-Duffy-Concurrent-Programming-with/RSS CLR Computing Parallel Extensions Programming Software Composability Code to Live: Rob Howard and Richard Hale Shaw on Opening the .NET Source Code ]]> http://channel9.msdn.com/Shows/Code+To+Live/Code-to-Live-Rob-Howard-and-Richard-Hale-Shaw-on-Opening-the-NET-Source-Code In this show, Rob Howard and Richard Hale Shaw discuss their opinions on opening up the .NET Source code and how that was done. 669 http://channel9.msdn.com/Shows/Code+To+Live/Code-to-Live-Rob-Howard-and-Richard-Hale-Shaw-on-Opening-the-NET-Source-Code Wed, 10 Oct 2007 05:40:55 GMT http://channel9.msdn.com/Shows/Code+To+Live/Code-to-Live-Rob-Howard-and-Richard-Hale-Shaw-on-Opening-the-NET-Source-Code joshholmes joshholmes 0 http://channel9.msdn.com/Shows/Code+To+Live/Code-to-Live-Rob-Howard-and-Richard-Hale-Shaw-on-Opening-the-NET-Source-Code/RSS CLR OSS Jack Gudenkauf - .Net 3.5 for ISVs Several weeks back James Vastbinder was able to coax Jack Gudenkauf into doing an interview on .NET 3.5 targeted at ISVs.  Jack is an Architect on the Base Class Library team and tasked to work with Microsoft’s ISV Partners. 

In this interview:

  • Jack talks about the BCL team and how they work within the larger Server and Tools business unit.
  • An inside view of the new Add-In Model in 3.5, (Its Jack's baby and he's rightly proud).
  • The Process ISV should mentally walk through when moving to managed code.
    Tools and utilities used by the CLR team.

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!

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 team.After the usual chat about how he ended up working for Microsft in theUS, Alessandro talks about the CLR: the discussion flows from Silverlight positioning to the aspects of hosting the CLR on highly reliable applications such as SQL Server. During the discussion Alessandro quotes a paper about CLR hosting, that can be downloaded from here; furthermore, he often mentions the blog CLR Inside Out (feed here).  

As usual, Alessandro will keep an eye on the comments; if you have questions please do not heistate to press on the “Reply button.

See you in the next episode!
