Questions tagged [serilog]

Serilog is a .NET library which provides diagnostic logging to files, the console, and so-on. Consider using this tag along with the .net framework version you are using for extra clarity

Serilog is a library that provides diagnostic logging to files, the console, and so-on. It is easy to set up, has a clean API, and is portable between recent .NET platforms.

Unlike other logging libraries for .NET, Serilog is built with structured log data in mind. Parameters passed along with log messages are not destructively rendered into a text format. Instead, they're preserved as structured data that can be written in document form to a data store.
