Negative connotations about the ecosystem

A lot of innovation from other platforms being applied

Very smart people using the platform as it’s the best choice for their circumstance

Not just the “alt” .NET community

Daunting for new developers

High signal-to-noise


Languages


1. F#

• What it is

• Microsoft’s official functional language on the CLR• Static type inference, multi-paradigm: FP + OO

• OCaml-esque• Source now publicly available!

• Geeks

• Don Syme (MSR)


1. F#

• Why look at it?• Business asking for “faster”?• Different way of thinking• Helps you understand LINQ and functional

abstractions in C#• Functional languages “buzz”


1. F#

• Resources• Matt Podwysocki http://weblogs.asp.net/podwysocki/• Planet F# http://feeds.feedburner.com/planet_fsharp• Hub FS http://cs.hubfs.net• Phillip Trelford http://www.trelford.com/blog/• Books:

• Programming F# (Smith)• Expert F# (Syme, Granicz, Cisternino)• Beginning F# (Pickering)• Real World Functional Programming (Petricek, Skeet)• F# for Scientists (Harrop)

2. HTML5

• What it is• The next version of HTML, still in review• More semantic markup

3. C# 5 “await”

complete• Creates continuation for execution by the task after it completes• Doesn’t actually “wait” or block the current flow

• Subscribe to sequence and error• .NET, Silverlight, JavaScript

• Geeks

4. Reactive Extentions(Rx)

• Why look at it

• Vastly simplified abstraction for handling events and dealing with asynchrony

• A “list” of event messages, a success or failure event• Rx manages sequencing of events, exceptions, callbacks,

timeouts

• Resources
