A Component Plug-In Architecture for the .NET Platform

Plug-in architectures and platforms represent a promising approach for building software systems which are extensible and customizable to the particular needs of the individual user. For example, the Eclipse platform, as the most prominent representative of plug-in systems, is based on a unique plug-in and extensibility concept and has succeeded in establishing itself as the leading platform for the development of tool environments. This paper introduces a new plug-in architecture for the .NET platform which shows much resemblance to Eclipse. However, whereas Eclipse is a Java-based system and uses XML to describe extensions, our architecture relies on .NET concepts such as custom attributes and metadata to specify relevant information directly in the source code of an application. We argue that this approach is more readable and easier to maintain. As a case study for our plug-in architecture we present a new plugin platform for implementation of rich client applications in .NET.
