Question

see the below code

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseStaticFiles();
}

public void Configure(IApplicationBuilder app IHostingEnvironment env ILoggerFactory loggerFactory) { } The Configure() method handles the HTTP request by configuring the request pipeline. Several extension methods are used to configure the pipeline.

you said ; loggerFactory.AddConsole() add log output when we run our app from the command line can we run asp.net web application from command line tool if we develop web application with VS2015 or VS2017 ? env.IsDevelopment() will help us to determine that code is running from IDE or exe/dll ?

Configuration.GetSection(Logging) access the appsettings values go to appsetting > Logging { Logging: { IncludeScopes: false LogLevel: { Default: Trace System: Information Microsoft: Information } } } loggerFactory.AddConsole() add log output when we run our app from the command line loggerFactory.AddDebug() add log output when we run in Visual Studio in Debug mode go to Output window in Visual Studio. we can access the log here's how: https://stackify.com/net-core-loggerfactory-use-correctly/ http://www.c-sharpcorner.com/article/working-with-built-in-logging-framework-in-asp-net-core/ env.IsDevelopment() is for managing the exception if happen in development or production environment get more about working with multiple environment: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/environments app.UseStaticFiles() is for serving the static files from /wwwroot like html css js get more details: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/static-files
