In this chapter, the first in this book about customizing ASP.NET Core, you will see how to customize logging. The default logging only writes to the console or the debug window. This is quite good for the majority of cases, but sometimes you need to log to a sink, such as a file or a database. Or, perhaps you want to extend the logger with additional information. In these cases, you need to know how to change the default logging.
In this chapter, we will be covering the following topics:
- Configuring logging
- Creating a custom logger
- Plugging in an existing third-party logger provider
