JetBrains.Annotations by: JetBrains

JetBrains.Annotations help reduce false positive warnings, explicitly declare purity and nullability in your code, deal with implicit usages of members, support special semantics of APIs in ASP.NET and XAML frameworks and otherwise increase accuracy of JetBrains Rider and ReSharper code inspections. All usages of JetBrains.Annotations attributes are erased from metadata by default, which means no actual binary reference to 'JetBrains.Annotations.dll' assembly is produced. If you need to preserve these attributes in metadata, just define 'JETBRAINS_ANNOTATIONS' conditional compilation symbol in your projects.

log4net by: 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
