How do I configure log levels in ASP.NET Core?

You can configure log levels in ASP.NET Core by modifying the appsettings.json file or using code in the Startup.cs.

Can you show me an example of how to set it in appsettings.json?

Sure! In your appsettings.json, you can add a section like this:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  }
}

What if I want to set different log levels for different namespaces?

You can specify different log levels for different namespaces by adding them under the LogLevel section in appsettings.json, like this:

"LogLevel": {
  "Default": "Information",
  "MyApp.Controllers": "Debug",
  "MyApp.Services": "Error"
}

Is there a way to configure logging in code instead of using appsettings.json?

Yes, you can configure logging in the ConfigureServices method in Startup.cs using the ILoggingBuilder interface.
