How to integrate hangfire into the DotnetNuke backend - dotnetnuke

Question

I have a long process method that needs to be handled by a background process. I am thinking of using a HangFire. It is a free and open-source framework that will allow you to easily perform background processing in .NET application. The catch is I am new to DNN and I don't know how to start. I am searching in Google on how to integrate it, but I can't find a reference for that. Anyone has an idea on how to integrate HangFire to DNN?

Answer 1

You have to create a .NET project and install Owin and Hangfire packages in the project.
In that project,
create an Owin startup class and put your Hangfire initialization code in the Configuration method like this:
using Hangfire;
using Microsoft.Owin;
using Owin;
[assembly: OwinStartup(typeof(DnnHangfireIntegration.Startup))]
namespace DnnHangfireIntegration
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
GlobalConfiguration.Configuration.UseSqlServerStorage("HangfireConnection");
app.UseHangfireServer();
app.UseHangfireDashboard("/desktopmodules/hangfire");
}
}
}
You must configure the hangfire dashboard to use '/desktopmodules/hangfire' URL so it won't be intercepted by DNN.
Compile your project and copy your project DLL, Hangfire DLL's and Owin DLL's to your DNN bin-folder.
Lastly, you'll have to update the web.config to tell Hangfire how to find your startup class. You can do this by using this appsetting:
<add key="owin:AutomaticAppStartup" value="true"/>
Also don't forget to add the connectionstring, you could also just reuse the existing connectionstring.
