LINQ explained with sketches - the eBook

After covering and collecting multiple parts of LINQ explained with sketches I bundled them all together in a small booklet with more explanation and code samples.

Therefore I present: LINQ explained with sketches - the eBook. Over 30 pages with smaller explanations and more LINQ operations than in my last post. Litte Bonus: There are interactive links with smaller examples to fiddle around with.
