.NET 3.0 provides some support for working with ZIP files. However, it has an important drawback: it only works for packages that are conformant to the Open Packaging Convention standard.

Visual Studio 2010 has support for code contracts that allow to express pre-, post-conditions and invariants to your .NET code. Let’ say you want to create a function to return a random value in a range. This could look like it: class Program { Random rng = new Random(); public int GetRandom(int min, int max) … Read more
Last week Microsoft published on DevLabs a .NET language for building parallel applications, called Axum, and earlier known as Maestro. This new language is build on the architecture of the web, on the principles of isolation, message-passing, fault-tolerance, loose-coupling. It is said to have a more succinct syntax than Erlang, and have the isolation advantage … Read more
