LinqBridge by: Atif Aziz

With Visual Studio's multi-targeting and LINQBridge, you can write LINQ to Objects (local) queries using the full power of the C# 3.0 compiler and yet create programs that require only Microsoft .NET Framework 2.0. LINQBridge is a re-implementation of all the standard query operators introduced with Microsoft .NET Framework 3.5's System.Linq.Enumerable class.

log4net by: The Apache Software Foundation

log4net is a tool to help the programmer output log statements to a variety of output targets. In case of problems with an application, it is helpful to enable logging so that the problem can be located. With log4net it is possible to enable logging at runtime without modifying the application binary. The log4net package is designed so that log statements can remain in shipped code without incurring a high performance cost. It follows that the speed of logging (or rather not logging) is crucial. At the same time, log output can be so voluminous that it quickly becomes overwhelming. One of the distinctive features of log4net is the notion of hierarchical loggers. Using these loggers it is possible to selectively control which log statements are output at arbitrary granularity. log4net is designed with two distinct goals in mind: speed and flexibility
