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

LibLog by: Damian Hickey

A source code package designed primarily for library and framework authors who want dependency free logging support in their component. Also useful in end applications. As of 5.0.0 it works with NetStandard2.0 and SDK projects. For legacy csproj format support use 4.x versions. If you are a library or framework author and you wish to provide logging support in your component there are a number of options: 1) Depend on a specific logging framework 2) Depend on Common.Logging 3) Implement your own ILog interface and make your consumers wire it up. Option 1 is not desirable because it forces your users to use a particular framework. Option 2 is not desirable because it will add yet more nuget package dependencies and project references with associated versioning concerns in addition to wiring up. Option 3 is desirable because it is dependency free but requires that your users to remember to write an adapter and wire things up. This package is a variation of option 3 but will automatically wire things up too. - It will add an ILog, ILogProvider etc to YourRootNamespace.Logging - ILog is one method to implement - Using optimized reflection, it transparently supports NLog, Log4Net, Serilog and Loupe without any wiring up required by an end user, if the end user simply has a reference to any of these logging frameworks.

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.
