The fifteenth part of the C# Object-Oriented Programming tutorial explains the use of events. Events can be added to a class to allow it to indicate when a specific action has occurred or is about to occur. Subscribers may then react to the event.

The release of Visual Studio 2008 updates C# to version, 3.0, with several key language enhancements and LINQ support. Part Two of this series will walk you through C#'s new LINQ support features and other time-saving enhancements.

The fourteenth part of the C# Object-Oriented Programming tutorial explains how to add delegates to classes and programs. Delegates are used to provide references to methods that may be altered at run-time. They are also essential when creating events.

With the release of Visual Studio 2008, Microsoft has updated the C# language to its latest version, 3.0. C# 3.0, contains several key language enhancements that support the recently-announced Language Integrated Query (LINQ) feature. This article, the first of a two-part series, will walk you through each of these new, time-saving language enhancements and provide a couple of code examples illustrating how to use them.

The thirteenth part of the C# Object-Oriented Programming tutorial describes the use of indexers. A class that has an indexer can be used in a similar manner to an array. Objects of the class can use array-style notation to present multiple values.

The eleventh article in the C# Object-Oriented Programming tutorial furthers the investigation of operator overloading. This time the overloading of the relational operators is described, allowing custom classes to be included in comparison operations.

C# 3.0: how to pass an anonymous types, and how to cast them.

These features include (but are not limited to) lambda expressions, extensions methods, anonymous types, implicitly typed local variables, automatic properties, and object initializers.

Eric Lippert argues that Immutable Objects are the future of C#. Here he offers directions that C# could go to improve the developer experience when writing programs that use immutable objects.

The ninth article in the C# Object-Oriented Programming tutorial continues the discussion of operator overloading. In this article, the overloading of the true and false operators is described, allowing an object to be used in conditional processing.
