Azure Functions Not Working VS2017

Question

I've downloaded VS2017 Community Edition to try out Azure functions and I can't get it to work. I've searched many post on Stackoverflow and Azure functions Github pages but nowhere there seems to be a complete documentation about anything.

Here's what I have:

Azure function:

namespace FunctionApp1
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static void Run([ServiceBusTrigger("ngctestqueue", AccessRights.Manage, Connection = "Endpoint=sb://ngcservicebus.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=SERVICE_BUS_KEY")]string myQueueItem, TraceWriter log)
        {
            log.Info($"C# ServiceBus queue trigger function processed message: {myQueueItem}");
        }
    }
}

host.json

{
  "disabled": false,
  "bindings": [
    {
      "name": "myQueueItem",
      "type": "serviceBusTrigger",
      "direction": "in",
      "queueName": "ngctestqueue",
      "connection": "connection",
      "accessRights": "manage"
    }
  ]
}

local.settings.json

{
    "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=ngctest2;AccountKey=STORAGE_ACCOUNT_KEY;EndpointSuffix=core.windows.net",
    "AzureWebJobsDashboard": "DefaultEndpointsProtocol=https;AccountName=ngctest2;AccountKey=STORAGE_ACCOUNT_KEY;EndpointSuffix=core.windows.net",
    "AzureWebJobsServiceBus": "Endpoint=sb://ngcservicebus.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=SERVICE_BUS_KEY",
    "connection": "Endpoint=sb://ngcservicebus.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=SERVICE_BUS_KEY"
  }
}

When I run the function via F5 locally, I get the following error:

Microsoft.Azure.WebJobs.Host: Error indexing method 'Func
tion1.Run'. Microsoft.Azure.WebJobs.ServiceBus: Microsoft Azure WebJobs SDK Serv
iceBus connection string 'AzureWebJobsEndpoint=sb://ngcservicebus.servicebus.win
dows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=SERVICE_BUS_KEY' is missing or empty.

My dev environment is as follows:

1) Windows 8.1 Pro

2) VS2017 Community 15.3.5

3) Azure Functions CLI 1.0.4

Any help would really be appreciated.

Thank you.

Connection property should be set to connection string name, not the value itself. The value will then be read from the config.

[ServiceBusTrigger("ngctestqueue", AccessRights.Manage, Connection = "AzureWebJobsServiceBus")]

You don't need to create host.json in local environment (it will be auto-generated by SDK).
