Using the Async CTP With Windows Phone
The Async CTP that exposes C# 5.0 features to be used with asynchronous programming is not just for the full .NET Framework. There are versions for Silverlight (4 and 5) and even Windows Phone (which can be viewed as Silverlight 4, but has a separate supporting assembly). To demonstrate, I’ve adapted my sample of the Mandelbrot set to Windows Phone, while taking advantage of the async features to keep the UI responsive. After creating the initial Silverlight for Windows Phone project, I’ve added...
Calculating PI in .NET
I always loved mathematics. Although I’m certainly not a mathematician by profession, I’m always intrigued and inspired by math’s pureness and cleverness. One of the simplest and fascinating aspects of math is the number PI . Described simply as the ratio of a circle’s circumference to its diameter, it’s a constant with infinite digits after the decimal point and most importantly, non repeating (at least as far as I know). There are many ways to calculate PI, as evident within the PI Wikipedia link...
Mandelbrot Set with C# 5.0 Async support
I’ve always been fascinated by the Mandelbrot set . It’s an intriguing set, and the fractals created are truly mind boggling. (for more information on the Mandelbrot, and other such sets, you can start with the above Wikipedia link). As part of my preparation for tomorrow’s session on C# 5.0 asynchronous programming, I’ve decided to create a WPF application to view and explore the Mandelbrot set, while taking advantage of those new asynchronous features. This turned out to be rather fun. Here’s the...
The Return (Appearance) of the Complex Type
Early in the ads for .NET 4.0, there were rumours about two types dealing with numeric stuff, BigInteger and Complex . In the Beta 1 phase, BigInteger has appeared (I’ve briefly blogged about it), but Complex was nowhere to be found. With the advent of .NET 4.0 Beta 2, I was happy to find the emergence of the Complex type in the System.Numerics namespace (and these numeric types have been moved to their own System.Numerics.Dll assembly). Complex is, of course, represents a complex number, with a...
