How to get a Console output in ASP.NET Core with IIS Express

问题

ASP.Net Core documentation here has a nice console logging output like in the picture below with colors for various LogLevels. I have now created an application in Visual Studio and I see that it now runs behind IIS Express and I don't see the console anymore. I remember when I did run beta, then it did pop up Kestrel directly with this nice Console output.

Is it possible to get this nice window now?

P.S. It's a bit strange that the documentation still contains these images that you cannot even see.

回答1:

Yes, it's possible with IIS Express. Use Microsoft.Extensions.Logging.Debug nuget package: https://github.com/aspnet/Logging/tree/master/src/Microsoft.Extensions.Logging.Debug. Configure logger in the Startup.cs:

loggerFactory.MinimumLevel = LogLevel.Debug;
loggerFactory.AddDebug( LogLevel.Debug );
var logger = loggerFactory.CreateLogger("Startup");
logger.LogWarning("Logger configured!");

And:

Console.WriteLine("Hi!");
