Iterators for VB
Visual Basic's Paul Vick recently revealed a proposal to add iterators in a yet named version. While meant to address the same use cases as C#'s yield return statement, the proposal looks more like something out of a function programmer's playbook.

Covariance and Contravariance in .NET Generics
Currently .NET languages such as VB and C# do not support covariance and contravariance for generics. While this is not likely to chance in the near future, people at Microsoft are talking about it.

XHTML 2 and HTML 5 continue to diverge
These two specs have quite different purposes and solve two distinct problems. XHTML 2 is document-centric. HTML 5 is targeted at sites that aren't best represented by a document. Both are supported by the W3C. Is another standards war brewing?

Parallel Mono
Recently we announced that Mono achieved full C# 3 support. Along with that comes support for Parallel LINQ. Parallel LINQ, part of Microsoft’s Parallel Extensions library, allows developers to quickly make queries execute across multiple threads.

Bill McCarthy asks “Are Iterators Fundamentally Flawed?”
Iterators are at the core of .NET programming. Only rarely do developers actually work against indexed data, preferring to use for-each loops for most tasks. But is this inherently sequential access method appropriate as we turn more to multi-threaded applications?

Debunking Common Refactoring Misconceptions
In comparison to Java, an emphasis on continuous refactoring is still relatively new in .NET. Besides having few ardent proponents, many myths linger around what refactoring really is and how it applies to the development process in general. Danijel Arsenovski, author of Professional Refactoring in Visual Basic, attempts to dispel some of these myths.

Duck Typing Using Runtime Code Generation
Duck typing techniques can be used in statically typed languages like C#, but it generally requires some tedious reflection code. But seeing the benefit of such techniques, some are turning to it anyways and are developing ways to make it less painful.
