如何关闭 ASP.NET core 框架完成的日志记录

如何关闭 ASP.NET 对每个请求进行的日志记录，例如

INFO 09:38:41 用户个人资料可用。使用“C:\Users\xxxx xxxx\AppData\Local\ASP.NET\DataProtection-Keys”作为密钥存储库和 Windows DPAPI 来加密静态密钥。
DEBUG 09:38:41 托管启动

..

我还没有找到如何关闭此日志记录...

这是我的Configure方法中的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?}");
    });
}

这是我的project.json 文件：

  "EntityFramework.Commands": "7.0.0-rc1-final",

Update:
我的 log4net 提供商被占用从这里 http://dotnetliberty.com/index.php/2015/11/09/asp-net-5-logging-with-log4net/

我不确定我是否遗漏了某些内容，但您难道不想提高 Microsoft 日志的日志级别吗？

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

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

To

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

或者通过环境变量进行相同的修改（假设.AddEnvironmentVariables())

Logging:LogLevel:Microsoft=None

您还可以更具体，以下减少了大多数条目但留下了Microsoft.AspNetCore.Hosting.Internal.WebHost at Information.

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

如果这不起作用，请道歉log4net
