.NET logging: Setup, configure and write a log with ILogger (uses .NET Core)

To configure .NET logging, the ILogger interface can be used when building an ASP.NET Core application in C#.

With .NET Core, the Microsoft.Extensions.Logging NuGet package provides us with a number of extension methods that allows us to log at different levels.

With the ILogger interface, we can use a logging provider which logs to a particular format. There are a number of logging providers available including log4net and Serilog.

In-addition, we can also build a custom logging provider that allows us to build a .NET logging library and allows us to format a log in the way we want it written.

This video looks at writing a log, the different log levels and how to set the severity for an assembly, and how to configure writing logs for different custom providers. By watching the video, it will give you an idea on the best practices for logging, and will give you an idea on how to use it for your framework.

Great video... How do you go about logging in a hosted service? I know you did a recent video about hosted services, just wondering how you can pass the logger to the hosted service.
