c# - How to turn off the logging done by the ASP.NET core framework

Question

How do I turn off the logging done by ASP.NET for each request e.g.

INFO 09:38:41 User profile is available. Using 'C:Usersxxxx xxxxAppDataLocalASP.NETDataProtection-Keys' as key repository and Windows DPAPI to encrypt keys at rest.
DEBUG 09:38:41 Hosting starting
DEBUG 09:38:41 Hosting started
INFO 09:38:41 Request starting HTTP/1.1 GET http://localhost:23369/
INFO 09:38:41 Request starting HTTP/1.1 DEBUG http://localhost:23369/ text/html DEBUG 09:38:41 DEBUG requests are not supported
DEBUG 09:38:41 The request path / does not match a supported file type
DEBUG 09:38:41 Request successfully matched the route with name 'default' and template '{controller=Home}/{action=Index}/{id?}'. DEBUG 09:38:41 Request successfully matched the route with name 'default' and template '{controller=Home}/{action=Index}/{id?}'. DEBUG 09:38:41 Executing action Forums.Controllers.HomeController.Index
DEBUG 09:38:41 Executing action Forums.Controllers.HomeController.Index
INFO 09:38:41 Executing action method Forums.Controllers.HomeController.Index with arguments () - ModelState is Valid'
INFO 09:38:41 Executing action method Forums.Controllers.HomeController.Index
..

I couldn't find yet how I can turn this logging off...

This is my Configure method in the Startup class:

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddProvider(new Log4NetProvider());

    if (env.IsDevelopment())
    {
        app.UseBrowserLink();
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");

        // For more details on creating database during deployment see http://go.microsoft.com/fwlink/?LinkID=615859
        try
        {
            using (var serviceScope = app.ApplicationServices.GetRequiredService<IServiceScopeFactory>()
                .CreateScope())
            {
                serviceScope.ServiceProvider.GetService<ApplicationDbContext>()
                     .Database.Migrate();
            }
        }
        catch { }
    }

    app.UseIISPlatformHandler(options => options.AuthenticationDescriptions.Clear());

    app.UseStaticFiles();

    app.UseIdentity();

    // To configure external authentication please see http://go.microsoft.com/fwlink/?LinkID=532715

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

And this is my project.json file:

"dependencies": {
  "EntityFramework.Commands": "7.0.0-rc1-final",
  "EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final",
  "log4net": "2.0.5",

  "Microsoft.Extensions.Logging": "1.0.0-rc1-final",
  "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0-rc1-final"
},

"commands": {
  "web": "Microsoft.AspNet.Server.Kestrel",
  "ef": "EntityFramework.Commands"
},

"frameworks": {
  "dnx451": { }
},

Update:
My log4net provider was taken from here

I'm not sure if I am missing something but don't you just want to raise the log level for the Microsoft logs?

Edit appsettings.json (assumes .AddJsonFile("appsettings.json", ...))

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Trace",
      "System": "Information",
      "Microsoft": "Information"

To

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Trace",
      "System": "Information",
      "Microsoft": "None"

Or the same modification via environment variables (assumes .AddEnvironmentVariables())

Logging:LogLevel:Microsoft=None

You can also be more specific, the following reduces most entries but leaves Microsoft.AspNetCore.Hosting.Internal.WebHost at Information.

"Microsoft": "Information",  
"Microsoft.AspNetCore.Mvc.Internal": "Warning",
"Microsoft.AspNetCore.Authentication":  "Warning"

Appologies if this doesn't work for log4net
