Welcome to the 100th episode of
Going Deep! It's been a great ride so far and I hope you've been enjoying the show over the years. For this momentous occasion, meet
Bart de Smet, a software engineer extraordinaire on the WPF team who spends his free time blogging (what an incredible wealth of truly useful technical information to be found
on
Bart's blog!) and creating custom LINQ providers. In fact, Bart is probably the world's most prolific LINQ provider creator, from LINQ-to-MSI to LINQ-to-Simpsons! How does he do it???
Of course, in this special episode who better to have involved in this LINQ'ified conversation (with lots of whiteboarding) than LINQ co-creator, programming languages designer, fundamentalist functional programming high priest and Channel 9 star Erik Meijer? In fact, given that this is an Expert to Expert Going Deep, Erik co-conducts the interview (and he's great at it as usual!). Nothing better than watching and listening to two experts geeking out at a whiteboard!
What makes LINQ so readily "providable"? How does Bart concoct his LINQ provider magic? Here, we dig into the details that enable LINQ-to-Anything.
Tune in. There's a lot of very useful technical information here (which I hope is the case for all 100 Going Deep episodes).
Enjoy and thanks for watching!

Thank you so much with your great work... Learned a lot from your previous videos Charles, hopefully there will be many many more to come !
Thanks all! I appreciate the kind words.
You can bet that I will be making more Going Deeps this year! Inside C#, Windows 7 and much more. Stay tuned.
Keep on watching,

I vividly remember the first (filter manager with Mr. Christensen) and the little snippet that "we are going to do more of these." Going deep has rapidly become my favorite show on Channel 9. Even if I am less than interested in the instant topic, it is fun to hear smart, passonate people talk about their technology.
Congrats on your 100th show. Can't wait to hear you say "lets talk about it" again.
bart is awsome too , that linq-to-simpsons stuff is some dark magic man..
I love that man!
And you too Charles!
What a great interview. I'd love to see more of Powershell by the way!
Maybe Jeffery Snover could do a few more videos? (hint-e-di-hint-hint)
The comparison of lazy evaluation to washing dishes just rocks!
Thank you. Very interesting and opened my eyes to other things. Inspired, I created a kind of Grep class for linq.

Sample:
Console.WriteLine("\nGet number of files and total size under a dir.");
long totSize = 0;
long totFiles = 0;
var q = (from f in new LFileInfo(@"c:\temp").Children(true)
let x = totSize += f.Length
let y = totFiles++
select f);
Console.WriteLine("Total Size:{0:N} Total Files: {1}", totSize, totFiles);
In theory any IQueryable provider should be addressable with LINQ through PowerShell. I haven't tested with the entity framework specifically though. It might be a totally unrelated problem like missing a configuration file that contains the connection string or so. Feel free to send me mail on "bartde at microsoft dot com" with a small project illustrating the failure condition, so I can step through it to see what's going on.
Thanks,
-Bart
