Matt Warren has put the IQueryable toolkit on CodePlex .  I’m excited about this for a number of reasons. I’ve commented before about how much I’ve learned reading Matt’s posts about building an IQueryProvider. That makes LINQ much more powerful.  However, building an IQueryProvider from scratch...

My last post on duck typing generated this question:   I have a question regarding your recent post about Duck Typing and anonymous type scope in C# 4.0.  Does this now open up the possibility of using an anonymous type (say, the results of a LINQ query) outside the scope of the method it was...

Today, the fine folks at InformIT posted another item from More Effective C# for you to learn more about the style and the content from the book: Item 29: Enhance Constructed Generic Types with Extension Methods If you have questions about the content, come by The Ann Arbor Computing Society (AACS) on...

A little while ago, I did a DNR TV on C# 3.0 . During that, I talked about preserving null semantics when  you write extension methods.  I made the point that you should never test if the first parameter of an extension method is null. That’s because it breaks the semantics of member methods...

Today is the official release date for More Effective C# . Writing a book may seem to be a solitary activity, but nothing could be further from the truth. I have been lucky enough to work with fantastic editors, technical editors, and community members as I have put this together. If you read the acknowledgements...

My last post generated valid criticisms from readers. Let’s clarify and correct that. Keith Elder commented: I got the impression reading your post that you "skimmed" my article and didn't really get what it was I was getting at. […] The whole point of this is C# 3.0 can be written where...

Keith Elder wrote a post a post asserting (or at least proposing) that a more imperative syntax for a problem is more readable than a LINQ based C# 3.0 version. (See here for his post). Well, that got my hackles up. Some days, my hackles get up before I do, but I digress. His example code as examining...

Paul Kimmel spent some time over the summer chatting with me about More Effective C# , LINQ, upcoming C# features, and the process of writing books. It's live here: http://www.informit.com/articles/article.aspx?p=1237069

Last week, I recorded a DNR TV with Carl Franklin discussing C# 3.0 extension methods, local type inference and some of the best practices that revolve around those parts of the languages. It's up and live now. Check it out here .

Patrick posted his solution earlier this week. I figure it was time to add mine. Also, Octavio Hernandez pointed out in the comments to problem 8 that he had discussed similar code constructs in his blog a while back. Problem 10 asks for the sum of all primes less than 2 million. It's also one line...
