Default Logger

By default, when using DI, you will be using Microsoft's implementation of ILogger and ILoggerFactory. This requires no additional setup.

Third Party Logger

If you wish to use a different logging service/implementation you simply install the appropriate nuget package, or create your own which have implementations for ILoggerFactory and ILogger.

You need to register either this third party implementation or your own via the IServiceCollection which becomes IServiceProvider at runtime.

If we are using the DisCatSharp ProjectTemplates there will be a project with a .Web. Inside is a Program.cs file.

WebHost: Serilog

• Serilog.AspNetCore
• Serilog.Extensions.Hosting -- Gives us the UseSerilog extension
• Serilog.Sinks.Console -- Sinks are used to direct where logs go. In this case we need it for outputting to console

using Serilog;

// unrelated code not shown for brevity
builder.Host.UseSerilog( (context, lc) => lc.WriteTo.Console()); // Our logs are directed to the console

var app = builder.Build();
app.Run();
