Run Azure WebJob on premises server - azure-webjobs

Question

The application I'm working on has to be deployable on Azure and on a Windows Server.
I'm using a Continuous Azure WebJob, that has some methods with a [TimerTrigger] attribute, that work fine on Azure. But I would like them to trigger also when deployed on premises.
Is this something supported? What would be a recommended way to have the exe with the Azure WebJob SDK running on a Windows Server continuously from a DevOps perspective?
I'm using .NET Core 3 and the Microsoft.Azure.Webjobs 3.0 SDK.

You can consider the web job project as a console project, and just click the your_webjob.exe to run it continuously(by specifying TimerTrigger). And you can follow this article to create a .NET core webjob.
Here is an example:
1.Create a .NET core 3.0 console project, and install the following nuget packages:
Microsoft.Azure.WebJobs.Extensions, version 3.0.0
Microsoft.Azure.WebJobs.Extensions.Storage, version 3.0.10
Microsoft.Extensions.Logging.Console, version 3.0.0
2.Here is the code in program.cs:
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
namespace ConsoleApp2
{
class Program
{
static void Main(string[] args)
{
var builder = new HostBuilder();
builder.ConfigureWebJobs(b =>
{
b.AddTimers();
b.AddAzureStorageCoreServices();
b.AddAzureStorage();
});
builder.ConfigureLogging((context, b) =>
{
b.AddConsole();
});
var host = builder.Build();
using (host)
{
host.Run();
}
}
}
}
3.Add appsettings.json file to the project, and then right click the appsettings.json file -> select properties -> set the "Copy to Output Directory" to "Copy if newer". Here is the appsettings.json:
{
"ConnectionStrings": {
"AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=xx;AccountKey=xxx;EndpointSuffix=core.windows.net"
}
}
Add a Functions.cs to the project. And here is the code in Functions.cs:
using Microsoft.Azure.WebJobs;
using Microsoft.Extensions.Logging;
namespace ConsoleApp2
{
public class Functions
{
public static void CronJob([TimerTrigger("0 */1 * * * *")] TimerInfo timer, ILogger logger)
{
logger.LogInformation("this is a test message!");
}
}
}
5.Build the project, then go to the folder where your_webjob.exe is located, just double click the .exe file, it can run continuously on local:
