It's a Whirlwind Tour of the important language features of C# 4. Stuart describes each major feature and why it is useful. But doesn't get into best practices nor suggested usages. Just the facts about each feature.

Whirlwinds are bite-sized webcasts, generally shorter than 15 minutes. You can start anywhere in the series to learn about the parts you're most interested in.

This session on C# 4 shows how the compiler handles eventing. The compiler no longer sets locks on events, instead uses a compare and swap technique. Stuart compares C# from .NET 3.5 and .NET 4 to show the differences and explains the implications for your existing code.

There's already a plethora of C# 4.0 content you can find out there (including here on Channel 9 itself), so we will dive in specifically to how the combination of named and optional parameters will help you simplify your code.

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. Enjoy. ]]> http://channel9.msdn.com/Shows/Going+Deep/Expert-to-Expert-Anders-Hejlsberg-The-Future-of-C It's always a pleasure to get a chance to sit down and geek out with Anders Hejlsberg. Anders is a Microsoft Technical Fellow (a Technical Fellow is the highest ranking technical position at Microsoft) and programming language design master. He's the creator of C# and one of the founders of .NET. Anders is an expert language design craftsman. C# is one of the most popular languages Microsoft has created and certainly the most widely used language by developers who target the .NET platform.

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.

So we took this opportunity to sit down with Niner-regular Anders Hejlsberg and C# Community PM Charlie Calvert to dive into some of the most common questions we are hearing about C# 4.0 and the reasoning behind some of the answers.

Samuel, Chris and Eric were very busy solving some really hard problems to pull these new features off. It's great to learn about these new features from the people who actually implemented them. Classic Channel 9!

So, how does C# 4.0's dynamic type work, exactly? What does "more COM friendly" really mean? Covariance and Contravariance? Optional parameters with default values and parameter re-ordering? Why? How? Tune in.

Enjoy!

There are some new faces (and some old ones (not in terms of age, mind you Smiley). As expected, merging functional constructs into imperative C# are still top of mind for the C# design team. Here, you'll meet some new programming language gurus and some old time Niners (you'll recall the great Eric Lippert. He was in fact the very first developer we interviewed for C9 back in 2004 - even though his was not the first interview posted, it was the first one shot and the one where Lenn, Jeff, Scoble, Bryn and myself looked at each other and said "wow, we are on to something here!".).

C# 4.0 will contain many new features that will help developers be, yeah, you've heard it before, more productive. There's also some very interesting work going on with adding dynamic constructs to the language, which is of course very interesting given the static nature of the C# language.

In this video you will not get any specific details since the C# team wants to reveal exactly what they've done at PDC 2008. That said, you'll still get a very clear sense of what they've been up to and where they're taking the language.

It's always a pleasure to chat with Anders and team. I think you'll enjoy this one. On a personal note, I was coming down with a cold during this interview so please excuse the asking of the same question more than once (though in a different context). Oh, the joys of cold medicine. You know, the same stuff Lenn was on when he conceived the idea of Channel 9 several years ago. ]]> http://channel9.msdn.com/Blogs/Charles/C-40-Meet-the-Design-Team What's the C# team up to these days? Who's on the C# 4.0 design team, anyway? With the looming problem of manycore facing developers now and certainly in the near future (to a much greater extent - programming for 80 core (asymmetric to boot) processors, anyone?). I thought it was time to find out what Anders et al are working on to get a clear sense of C#'s near (and not-so-near) future so I asked if I could come to one of their design meetings to have an informal chat (are we ever formal on C9?) and meet the people behind the next iteration of the most popular .NET programming language.There are some new faces (and some old ones (not in terms of age, mind you ).
