Professional Developers Conference 10 took place October 28-29 on Microsoft campus in Redmond, WA. At this event, we shared Microsoft’s future directions for C#, Visual Basic and F#, and produced a lot of great content! Here’s a roll-up of the materials.
Anders’ talk was the #1 most-viewed and #1 highest rated breakout session at the event! This was the session where we announced the Async CTP and gave an update on project codename “Roslyn”. You can watch the video on-demand here. Learn about all the improvements planned to improve asynchronous programming in the next version of C# and Visual Basic, with no more callbacks!

In this session, Charles Torre interviewed the Async design team with questions from the audience about the Async CTP. You can watch the video here.
The Async CTP has generated a lot of buzz. We’ve totaled over one million touch points with developers around the Async CTP, between PDC videos, Channel9 videos, Blog views, whitepaper downloads, web page views, and more. The Async CTP WebPage is a top visited page on the MSDN Dev Centers. More details on Async CTP content below.

In the last section of the C# & Visual Basic Futures session, Anders gave an update on project codename “Roslyn”, also known as compiler as a service. “Roslyn” is a long lead project in which we’re re-writing the C# & Visual Basic compilers in C# & Visual Basic, respectively. The new managed APIs will allow developers to query the compiler for information. We are looking forward to the new scenarios that this will enable, including a Read-Eval-Print-Loop (REPL), and a host of rich IDE features.

Lucian Wischik and I recorded a podcast with Jesse Liberty on his show, Yet Another Podcast. We discussed the Async CTP, Productivity Power Tools, and Visual Basic for Windows Phone. Mads and Lucian produced another podcast about Async on SkillsMatter a couple of few weeks later.
We had a Visual Studio booth and used this as a place to follow up for additional information outside of sessions. Team members Avner Aharoni, Alex Turner, Karen Liu, Mads Torgersen, Lucian Wischik, and Kevin Pilch-Bisson spent time at the booth, demoing new features and answering questions.
Ask The Experts (ATE) was held both days at lunch. Over 45 team VS Pro team members participated in the event, and had some great conversations attendees. This included 10 tables across C#, Visual Basic, F#, IDE, and Extensibility.
On Friday at Ask The Experts, we also advertised “Meet Anders” and “Meet Don” tables. These were a big hit and had a great turnout. Here’s a quote from one attendee:
@Edcomingatyou: I just had lunch with Anders Hejlsberg. Pardon my language but how f#@%ing cool is that? #pdc10
