It's not often I find a truly interesting blog post on C#...

There’s a certain set of special method signatures in C# which have particular support on the language level. Methods with those signatures allow for using a special syntax which has several benefits. For example, we can use them to simplify our code or create DSL to express a solution to our domain-specific problem in a much cleaner way. I came across those methods in different places, so I decided to create a blog post to summarize all my discoveries on this subject.
Very cool.

I’ve discovered this language feature by accident...
I hope the feature is documented instead of being an accidental side effect of the current implementation!

Of course it's documented! It's documented right there in that blog post you just read! :laugh:
The author does actually suggest linking to his blog if your co-workers don't understand your code when it uses one of these spiffy features! :laugh:

I thought you might find that interesting. And yes, agreed! Learned new stuff!

It's a syntactic side effect of the Add and Item methods. If you set a value of a dictionary via the Item method and the key doesn't exist the class will add the key and value. It is a very nice and clean way of writing:
var errorCodes = new Dictionary
{
{[404], "Page not Found"},
{[302], "Page moved, but left a forwarding address."},
{[500], "The web server can't come out to play today."}
};As I stated previously, there is nothing in this guy's blog that isn't directly the result of the C# and dotNet framework class documentation.

Abusing Extension Methods, Null Continuation, and Null Coalescence OperatorsHe hints at it but doesn't show what you can do with the LINQ pattern. You can do fun stuff like this:
void Main()
{
var notACollection = new MyClass();
var x = from a in notACollection
where a.DoesntMatter == 5
select "Greetings Earthling";x.Dump(); // Prints "HELLO, WORLD!" } class MyClass { string \_msg; public int DoesntMatter; public MyClass Where(Func \_) { \_msg = "Hello, World!"; return this; } public string Select(Func \_) { return \_msg.ToUpperInvariant(); } }Truth, James
