In this video I’ll cover LINQ. Language Integrated Query (LINQ) provides many tools for working with data. LINQ is similar to SQL, but it can work with data aside from databases. I’ll cover From, Where, Orderby, Select, In, Inner Joins, Group Inner Join, Equals and using LINQ with multiple different collections.

For best results take notes on the cheat sheet provided above as you watch and leave any questions you have.

    Hi Derek, currently bench watching this. I was wondering why using a Arraylist instead of a generic List, is there any difference in performance speed or memory wise ?

    15:45 just curious, are you creating a new Animal object, or some anonymous type?

    Also, I can kinda see how the "nums" list updated itself (earlier in the tutorial), but even more confusing, how did the array after it update itself since you passed in "nums" before you updated it

    Hi Derek, If you were to build a Pateron style Webapp what stack would you use ?
    Would a MEAN stack work well as compared to the classical MVC style using Django or flask or PHP ?

    Sorry for my total off topic question about this video, but do you have a preference on tutorials/book for C# and Unity? I know you plan to do videos (thank you extremely!), but I've also been trying to find some other sources for that too; if you know any that'd be awesome 🙂 Thanks Derek, keep up the good work!

    ​could you maybe make a tutorial on how to search multiple tables, where some are connected with many to many tables. And make sure to stream some more the witness 🙂

    Hey Derek. I just have a question, do you need to be extremely good at maths to be a hacker or a programmer? Because that's what some people are posting on the Internet.
    If yes what exactly and specifically do you require?

    Derek, If you had an ubertooth one and had to make it able to sniff packets in monitor mode with packet injection where would you start???? What would it be scripted in if you had to choose? if you had to make it like airodump-ng but for bluetooth where would one start to make something for it?

    Thank you for another great tutorial! Could you do one on XAML?

    very useful tutorial! Thank you for devoting your time! 🙂

    Great tutorial, just a pity you used the non functional SQL-like syntax, the least preferred syntax. The extension methods are way more succinct, composable and aligned with other functional languages.
