I have been trying to refer a .net core library project into my Azure function project to call one of the process defined in a .net core class library.
The .net core library project uses ILogger.
However, whenever I try to run a function I get the following error:
[29/11/2019 1:08:35 AM] The 'Function1' function is in error: Microsoft.Azure.WebJobs.Host: Error indexing method 'Function1'. Microsoft.Azure.WebJobs.Host: Cannot bind parameter 'log' to type ILogger`1. Make sure the parameter Type is supported by the binding. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(),
This is my code:
[FunctionName("Function1")]
public static void Run([TimerTrigger("0 */5 * * * *")] TimerInfo myTimer, ILogger log)
{
log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
// string templateFile = Path.Combine(context.FunctionAppDirectory, "Data", "HelloHttpOutputTemplate.txt");
Startup.Main(null).Wait();
}
I also confirmed that my .net core project as well as function project are referring a same version of ILogger:
'microsoft.extensions.logging.abstractions\3.0.0\lib\netstandard2.0'
If I remove a .net core library project reference from within function project then it works.
