How factoring out common patterns in your Azure worker roles can improve development.

Looking Ahead to C# 4.0: Optional and Named Parameters

Optional and named parameters were added to the C# language for COM and Office interoperability, but these features are actually useful in a variety of ways.

Working Effectively with Exceptions

Exceptions are a way of life in the .NET world. You must follow the rules to make your classes easy to use for other developers. Conforming to the standards will make everyone's life easier.

Generic Covariance and Contravariance in C# 4.0

Covariance and contravariance are precise terms that describe which conversions are safe on parameters and return types. Learn practical definitions for those terms, what new constructs will be supported in C# 4.0 and how to live with the current limitations until Visual Studio 2010 is adopted by your organization.

Make Your Code Clear

There are multiple ways to solve every problem. Strive for code that communicates your intent and makes your meaning clear for every developer who uses it.

Create Anonymous Types

Taking a careful look at the capabilities the compiler gives to anonymous types provides an excellent tutorial on what you should consider when you create your types -- including whether they are classes or structs.

Use Lambda Expressions for Abstract Delegates

Lambda expressions are nothing more than convenient syntax for delegates. So why can't you use them where the Framework expects a delegate? And more importantly, what can you do about it?

Target Multiple .NET Frameworks

Many developers have the misconception that targeting older versions of the Framework means you can't use any of the new C# language features. It's time to dispel that myth.

What VB Devs Should Know About C# Programming

Chances are C# is not your first programming language. Here are several tips that can help you leverage C# better if you already know VB.NET.
