NLog and Elmah logging for Net.Core applications.

Net.Core Logging

Two examples of logging in ASP.Net Core. At first, in program.cs file add the following code to set logging (this is my setting):

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .ConfigureLogging(logging =>
        {
            logging.ClearProviders();
            logging.SetMinimumLevel(LogLevel.Trace);
            logging.AddDebug();
            logging.AddEventSourceLogger();
        })
        .UseStartup<Startup>();

Now you can decide which provider to use:

• NLog

After installing the NuGet package. Edit nlog.config file to set the local file path ("D:" in my case). In the main procedure, instantiate the NLog, by indicating the Nlog config file:

  var logger = NLog.Web.NLogBuilder.ConfigureNLog("nlog.config").GetCurrentClassLogger();
  

The logging file will be saved in the path you set in the config file.

• Elmah

After installing the NuGet package, add in configure method in startup.cs the following instruction:

app.UseElmah();

The logging result will be shown in the page https://yoururl/elmah.
