Add Structured Logging to your .NET Apps with Serilog

Install the Serilog.AspNetCore package and configure it in your DI container

// Configure Serilog
Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(configuration)
    .Enrich.FromLogContext()
    .CreateLogger();
host.UseSerilog();

Load the configurations from your appsettings.json file as it's the most flexible option
