Azure-docs: Error on Enable console logging

[ravick4u]

When I was following this document got blow error on line "config.LoggerFactory = loggerFactory.AddConsole();" under section "Enable console logging"

_'JobHostConfiguration' does not contain a definition for 'LoggerFactory' and no extension method 'LoggerFactory' accepting a first argument of type 'JobHostConfiguration' could be found_

Looks like I am missing some reference.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Azure.WebJobs;
using Microsoft.Extensions.Logging;

namespace AzureJob
{
    // To learn more about Microsoft Azure WebJobs SDK, please see https://go.microsoft.com/fwlink/?LinkID=320976
    class Program
    {
        // Please set the following connection strings in app.config for this WebJob to run:
        // AzureWebJobsDashboard and AzureWebJobsStorage
        static void Main()
        {
            var config = new JobHostConfiguration();

            if (config.IsDevelopment)
            {
                config.UseDevelopmentSettings();
            }

            config.DashboardConnectionString = "";
            var loggerFactory = new LoggerFactory();
            config.LoggerFactory = loggerFactory.AddConsole();

            var host = new JobHost(config);

            // The following code ensures that the WebJob will be running continuously
            host.RunAndBlock();
        }
    }
}

@ravick4u Thanks for your feedback! We will investigate and update as appropriate.

I have exactly the same problem after following the document guide

I had the same problem, and eventually realized it was because the Microsoft.Extensions.Logging package had failed to install. After changing the target framework to 4.6.1 and reinstalling the logging package, it worked as expected.

@ravick4u @Noissim I was able to work through the sample doc with no issues. I used 4.6.1 framework and made sure to use 2.2.0 version of webjobs.

It looks like @wjmoody03 was able to resolve the issue by ensuring he used similar versions. Can you please check this part of your projects?

[Noissim]

@BryanTrach-MSFT Upgrading to WebJobs 2.2.0 did the trick. Thanks!

[BryanTrach-MSFT]

@ravick4u Since we have not heard back from you and we have three others verifying the resolution, we will proceed to close out this thread. If you have any further questions, please tag me in your reply.

@Noissim Great to hear. Thank you for updating us. Have a great weekend.
