Routing settings for Areas in ASP.NET Core

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();

}

please tell me the meaning of these line of code

loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();

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

thanks
