Thanks for the video Alim, really helped me get to grips with LINQ.

I think there is a mistake in the video at the 27 minute mark. You say that you're turning lazy loading off because loading data from the Employee table would also load all the associated data from the Designation and Person tables. What you're describing is eager loading. In fact, lazy loading does the opposite. It will only load associated data from the Designation or Person tables if a reference is made to one of their properties. So it's actually much less costly.

Wow! Thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you. Finally I have understood how to use LINQ.

Holy cow of sand! (hahaha) This is a powerful bitch.

BTW, , you were excellent differentiating the tidbits of each LINQ method. What I mean, is that many methods may look the same, but have something different.

For instance, at 21:56 you managed to explain me the difference between using a TakeWhile and Select.
