Azure Function App Not triggering TimerTrigger in Visual Studio Debug

I have Azure Function app that I was able to debug previously but now it would not trigger when I start it in Visual Studio debug mode. Function looks like this:

public static void RunDownloadTask([TimerTrigger("0 */30 * * * *")] TimerInfo timerInfo, TextWriter log)
{...}

When I started in debug in Visual studio I used to get output like the following, but now I only get the first two lines of message in console. The rest "The next 5 occurrences ..." does not show up, and the function never gets triggered. Has anyone experienced something like this and know how to fix it? Looks like the instances I deployed to Azure App Service continue to work, but I don't know why I can't run this in debug mode locally anymore.

Found the following functions:
ChaseFTPDownloader.Functions.RunDownloadTask
The next 5 occurrences of the schedule will be:
10/5/2020 4:30:00 PM
10/5/2020 5:00:00 PM
...

I can reproduce your problem:

enter image description here

This is the problem of the settings of the Visual Studio.

Solution:

Just right click your functionapp in VS and add this command to the properties of your project:

start --verbose

enter image description here

enter image description here

After that you will see the log like before:(this change is updated in recent months.)

enter image description here

I think your function should start. Why you don't see it triggered is because the cron expression of your timetrigger.(It has an interval of 30 minutes and will not trigger the first time.)

Please do a test and let me know whether this can help you.
