This tutorial covers Microsoft's new programming language C#. It is aimed at people with some programming experience, although it tries not to assume too much knowledge.

This is a set of lessons suited for beginning to intermediate programmers or anyone who would like to gain familiarity with the C# programming language. These lessons will help you get a quick head-start with C# programming.

A article comparing the main differences between the two languages.

A quick reference guide to highlight some key syntactical differences between Java and C#.

In this document you will learn about creating testing classes for your project. One of the hardest tasks when using a new tool is learning how to integrate it into your regular build lifecycle. Hopefully this tutorial will help you in creating new test classes, maintain your existing test classes, and take advantage of advanced features in the csUnit API.

As with anonymous methods, iterators are a non-obvious but powerful feature introduced in the version 2 of C#. Iterators can be qualified as syntactic sugar since they don’t imply any CLR/IL instruction set changes compared to .NET 1.x. Just like anonymous methods, all the magic is in the compiler. To understand the underlying motivations of C#2 iterators, we’ll first dig into C#1 iterators. Then, we’ll cover the basics of this feature in version 2, following with an analysis of the compiler’s work. Finally, we’ll drill into advanced uses of C#2 iterators.

Generics are often introduced as the mainstream language feature of Whidbey (.NET2). However, while surfing off the beaten path I realized that new features named anonymous methods and iterators are also very interesting. Unlike generics, these two features don't imply new IL instructions set changes compared to .NET1 IL instructions set or any CTS changes. All the magic is in the compilers.

Provides a very thorough explanation of what happens during an HTTP request to an ASP.NET page being served up through IIS. A thorough knowledge of this process is invaluable when debugging strange problems, developing ASP.NET custom web controls or developing any sort of web framework.

Do you have an ASP.NET page that performs a long-running (>100ms) I/O request, like making an HTTP request or executing a costly SQL command? Has your ASP.NET web application unexpectedly hit its maximum throughput? Do ASP.NET web requests start queuing when your web server is under significant load? If so this article may help you address these issues.

This article discuss custom iterators, predicates, and generic methods. You can combine these three techniques to create small building blocks that plug together in a variety of ways to solve everyday development problems. Once you can recognize when to apply this pattern, you will be able to create a large number of reusable building blocks.
