Excellent stuff.

So as a follow up comment to the GC related discussion, Shawn mentioned that they were all initially "skeptical" of using managed code for game development. I have a feeling that the XNA team was a great source of motivation to optimize .Net in ways that makes sense for "realtime" applications like a games. So I'd be interested to know what influence the XNA team had with the .Net team in this respect. I mean, they must communicate, right?

Shawn also basically mentioned that when using XNA, you are still required to have a deep understanding of the memory management in .Net (EDIT: For instance, did you know that calling properties that implement an interface will automatically box any value types? I didn't, and how are we supposed to know this?). This is what my question was related to, and how we basically give up a huge part of the advantage of using a managed language. This problem can be solved almost completely by moving to an incremental/concurrent GC. With this, you no longer have to sweat the small things, and some amount of garbage per frame would be completely acceptable, even if your heap is complicated (almost a given in a complex game).

I understand this is complicated, and we won't see something like this soon. But what is being done in this regard, and are they even talking about evolving the GC in this direction, even if some time off into future? I think it is worth mentioning once again that Java has an optional low-latency incremental GC, so it is not impossible to do this.

There will probably be a second part where they answer our questions.

Good topics would be introduction to game dev, with the complexity increasing everyday to games techniques sometimes is hard to step into game development.

Nic, "astro turfing"? What does that mean?

Thank you for doing this. This will be an excellent series for XNA developers.

If you know anything at all about XNA you don't need to watch this. You should put in the description (or better yet in the questions thread) that they won't be able to talk about future versions so we know there's zero chance of anything interesting being disclosed.
Even the stuff about GC was just a sampling of Shawn's standard chat on GC in XNA - which if you're really interested in you should watch his MIX10 presentation instead. Of course he can't  mention of whether they are ever going to improve the GC in the compact framework.

Hmm. I don't understand the connection between a question on managed optimization strategies and myself Smiley

I thought this interview was informative and well worth the time spent watching it. Seems you're asking for things no product group will address since future directions tend to be moving targets - it's not a good idea to share a plan with customers that is not yet final or realistic.... Remember Longhorn and WinFS? Smiley

General discussions about possible hypothetical tech directions are often ok, but usually end up being so vague that they aren't really interesting, and when it comes to specifically announcing things that we will do in the future, well, that belongs to the marketing folks who like to plan the disclosure out nice and carefully, and would get rather upset if Charles and I stole their thunder!
Plus, the smoke still hasn't entirely settled from shipping our last major version, so we don't entirely even KNOW what we'll be doing next...
But there are tons of things we can talk about in the present without needing to mess with the future. What's in XNA Game Studio today, how best to use it, general game making techniques, graphics programming, creating game graphics, how to make sounds, game design, Xbox stuffs, Windows Phone stuffs...  All good fodder and I hope they'll have us back sometime to talk more about such things!

If it is on XNA future stuff, as both charles and shawn pointed out, they can't talk about.

but if you're asking us to ask the questions you want us to ask, that im pretty sure you're out of luck. niners resist editing Smiley

tutorials are great though, i'd like some more tutorials and informational videos on both xna and directx. but from an interview like this, people will enevitably want to know about other things than v.current.
