Open source .NET libraries you should be already using

As we know, there are many good, enterprise level, open source libraries, frameworks and projects implemented in Java. Most of them are being ported into different platforms like .NET and PHP, so developers are migrating to the these platforms with their familiar tools. For example, i have been using Ant, JUnit, Log4J, iText and many mores when i was developing in Java, but now i am still using Log4Net and Nunit in my current .NET projects. You can find many more open source .NET alternatives from the following list;

• AOP.NET (NAop) is an Aspect Oriented Programming (AOP) framework for .NET framework

• ZedGraph is a set of classes, written in C#, for creating 2D line and bar graphs of arbitrary datasets. The classes provide a high degree of flexibility -- almost every aspect of the graph can be user-modified. At the same time, usage of the classes is kept simple by providing default values for all of the graph attributes. The classes include code for choosing appropriate scale ranges and step sizes based on the range of data values being plotted. ZedGraph also includes a UserControl interface, allowing drag and drop editing within the Visual Studio forms editor, plus access from other languages such as C++ and VB
