Azure WebJob deployment issue

Question

I have a basic Azure WebJob, when i'm running through VS it runs and print the desired output as belown

But when i deploy and run from portal, I'm getting below error.

[07/15/2020 07:23:03 > 8f28d2: SYS INFO] Status changed to Initializing
[07/15/2020 07:23:03 > 8f28d2: SYS INFO] Job directory change detected: Job file 'RedmineSyncUp.exe' timestamp differs between source and working directories.

I'm deploying through VS.

Here is the my code.

Function.cs

public class Functions
    {
        // This function will get triggered/executed when a new message is written 
        // on an Azure Queue called queue.
        public static void ManualTrigger([Table("log")] CloudTable logTable)
        {
            for (int i = 0; i < 5; i++)
            {
                DateTime dt = DateTime.Now;

                Console.WriteLine(dt.ToString());
            }
          
        }
    }

Program.cs

static void Main()
        {
            try
            {
                JobHost host = new JobHost();
                Task callTask = host.CallAsync(typeof(Functions).GetMethod("ManualTrigger"));

                Console.WriteLine("Waiting for async operation...");
                callTask.Wait();
                Console.WriteLine("Task completed: " + callTask.Status);

                host.RunAndBlock();
            }
            catch (Exception ex)
            { Console.WriteLine(ex.Message); }
           
        }

If i deploy using published package also the result is same.

It looks like this error is related to WebJobs's targeted .Net Framework.

Can you please see which .Net framework are you targetting? Can you change the webjob's target framework to 4.7 and see if it works?
