C# 3.0 Syntax Additions—Design Guidelines

This is MUST read from every dotNet programmer. It is written by Peter Ritchie on DevX.com and presents the new features of C# 3.0 syntax.

These guidelines will help you understand new additions to C# 3.0 syntax and avoid some of the pitfalls you can encounter when using them.

C# 3.0 includes a few syntactical additions to the language. For the most part, Microsoft added these language additions to support Language Integrated Query (LINQ). These features include (but are not limited to) lambda expressions, extension methods, anonymous types, implicitly typed local variables, automatic properties, and object initializers.

Most of the syntax additions fulfill very specific needs and should not reduce the importance of established coding and design methodologies and guidelines. When in doubt, prefer your established guidelines over the new syntax.
