Comment Feed for Channel 9 - Expert to Expert: Erik Meijer and Bart De Smet - LINQ-to-Anything http://ecn.channel9.msdn.com/o9/previewImages/100/424226_100x75.jpg Channel 9 - Expert to Expert: Erik Meijer and Bart De Smet - LINQ-to-Anything 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! en Wed, 22 May 2013 04:48:53 GMT Wed, 22 May 2013 04:48:53 GMT Rev9 Re: Expert to Expert: Erik Meijer and Bart De Smet - LINQ-to-Anything posted by tomkirbygreen

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.

Erik Meijer

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)

Very interesting and opened my eyes to other things. Inspired, I created a kind of Grep class for linq.

http://staceyw.spaces.live.com/blog/cns!F4A38E96E598161E!1314.entry

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
