dotnet core logging showing info result always - asp.net-core

Question

I am learning .net core logging. I have read some blogs and docs also.
I am wondering why it's showing always "Microsoft.Hosting.Lifetime" Information logs every time with following settings.
{
"Logging": {
"LogLevel": {
"Default": "Error",
"Microsoft": "Error",
"Microsoft.Hosting.Lifetime": "Error",
"DemoWeb.Controllers.HomeController": "Error"
}
},
"AllowedHosts": "*"
}
To double check(If my appsettings.json is working) I added this in ConfigureService.
public void ConfigureServices(IServiceCollection services)
{
services.AddLogging(config =>
{
// clear out default configuration
config.ClearProviders();
config.AddConfiguration(Configuration.GetSection("Logging"));
config.AddDebug();
config.AddEventSourceLogger();
config.AddConsole();
});
services.AddControllersWithViews();
}
It's working as expected for my own added "HomeController" Class.
I just want to remove "Microsoft.Hosting.Lifetime" from console logs.
Thanks in advance

Firstly, as #KirkLarkin mentioned, in development, appsettings.Development.json configuration would overwrite values found in appsettings.json.
For more information, you can check : https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-3.1#appsettingsjson

In your project, multiple logging providers can be enabled. If you just want to turn off Information level logs about "Microsoft.Hosting.Lifetime" from ConsoleLogger, you can try to apply log filter rule(s) as below.
services.AddLogging(config =>
{
// clear out default configuration
config.ClearProviders();
config.AddConfiguration(Configuration.GetSection("Logging"));
//add log filter for ConsoleLoggerProvider
config.AddFilter<ConsoleLoggerProvider>("Microsoft.Hosting.Lifetime", LogLevel.Error);
config.AddDebug();
config.AddEventSourceLogger();
config.AddConsole();
});
And you can achieve same by configuring logging for that specific provider.
"Console": {
"IncludeScopes": true,
"LogLevel": {
"Microsoft.Hosting.Lifetime": "Error"
}
}
