.NET Tools Round-Up
Since the first announcements of Microsoft's new .NET platform, ActiveX control developers and tool vendors have been scrambling to adjust their products and their marketing strategies. This article reports on the changing component market and points you to many of the newly announced .NET Developer Tools.Since the first announcements of Microsoft's new .NET platform, ActiveX control developers and tool vendors have been scrambling to adjust their products and their marketing strategies.

How Microsoft Builds Community
During the Visual Studio .NET Launch February 13 at VSLive! 2002 in San Francisco, Markus Egger and David Stevenson of Component Developer Magazine interviewed a panel of Microsoft personnel about the concept of developer communities.In this free-ranging discussion, we learned how Microsoft desires to support and encourage the growth inside developer "ecosystems" by focusing considerable resources on "community outreach."

UML Collaboration Diagrams
In well-designed software systems, powerful business objects work together to accomplish a variety of tasks.UML collaboration diagrams are great tools for documenting the flow of messages between objects while providing a unique perspective - a view of the relationships between collaborating objects.

Introducing .NET My Services
.NET My Services is Microsoft's first attempt at creating a professional, commercial and widely available Web Services platform.The .NET My Services umbrella hosts a number of different Web services, such as a Calendar service, a Contacts repository, and much, much more. These services are major building blocks for the "Everywhere, Anytime" vision, but best of all, they are relatively easy to implement and use in your own applications and Web sites!

ASP.NET Caching Strategies
ASP.NET provides developers with the ability to cache dynamically generated pages.This means that it is now possible to cache pages built on posted data and querystrings! For instance, an e-commerce site that generates the same catalog from the database over and over on nearly every user request can now simply cache the catalog pages. Caching saves precious database server CPU cycles and renders pages down to the client much faster. Of course, when the catalog data is updated, the cache can simply refresh itself. Furthermore, developers can define the length of time an item is to be cached, indicate cache dependencies, create cached versions per browser, and indicate where an item should be cached (client, server, proxy, etc.).

Retrieving HTTP content in .NET
HTTP content retrieval is an important component for applications these days.Although .NET reduces the need to explicitly retrieve content from the Web through built-in mechanisms in the Web Services framework, ADO.NET and the XML classes, there are still many needs to retrieve Web content directly and manipulate it as text or data downloaded into files. In this article, I will describe the functionality of the HttpWebRequest and HttpWebResponse classes and provide an easy to use wrapper class. The class simplifies the HTTP access and provides most of the common features in a single interface while still providing full access to the base functionality of the HttpWebRequest class. In the process, I will describe some sticky issues like string encoding and Cookie handling and some related topics like implementing events and running multiple threads to service Web requests.

.NET Interface-based Programming
In component-based programming, the basic unit of use in an application is a binary-compatible interface.The interface provides an abstract service definition between the client and the object. This is in contrast to the object-oriented view of the world that places the object implementing the interface at the center. An interface is a logical grouping of method definitions that acts as the contract between the client and the service provider. Each provider is free to provide its own interpretation of the interface and its own implementation. To use a component, the client only needs to know the interface definition and have a binary component that implements that interface. This extra level of indirection between the client and the object provides for interchangeability between different implementations of the same interface, without affecting client code.
