Hangfire in IIS 6

question
1

Hello,

Does any body knows a way to use the Hangfire in IIS6?

I am getting the following exception

This operation requires IIS integrated pipeline mode.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.PlatformNotSupportedException: This operation requires IIS integrated pipeline mode.

Currently it is not possible for use to update the IIS.

My question is it possible to use Hangfire with IIS 6?

Regards
//Farid

Can you say me what operation is not supported by providing the full call stack for this exception?

Your application may be running in ‘Classic’ mode. Change the application pool to ‘Integrated’.

“Integrated” app pool is a new feature in IIS7. Do you have any idea what is the alternative/equivalent of this in IIS6?

According to this post, classic pipeline is not supported by OWIN. However, OWIN is required only by dashboard UI, so you can configure background server as written here and install separate console, service or web application with integrated pipeline for dashboard ui.

I am not sure what to do. I tried this link to initialize hangfire without the Owin and got the following error.

The following errors occurred while attempting to load the app.
- No assembly found containing an OwinStartupAttribute.
- No assembly found containing a Startup or [AssemblyName].Startup class.
To disable OWIN startup discovery, add the appSetting owin:AutomaticAppStartup with a value of "false" in your web.config.

To specify the OWIN startup Assembly, Class, or Method, add the appSetting owin:AppStartup with the fully qualified startup class or configuration method name in your web.config.

Stack Trace:

Coding

Private _backgroundJobServer As BackgroundJobServer
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
_backgroundJobServer = New BackgroundJobServer()
    _backgroundJobServer.Start()
End Sub

Sub Application_End(ByVal sender As Object, ByVal e As EventArgs)
    ' dispose the Hangfire
    _backgroundJobServer.Dispose()
End Sub

Configuration to disable the Owin, as per this link

Remove Hangfire (it contains only links to dependencies, main package is Hangfire.Core, you should leave it installed) and Microsoft.Owin.Host.SystemWeb packages from your projects and delete Microsoft.Owin.Host.SystemWeb.dll from the project output path (bin folder by default).

New problem,

JobStorage.Current property value has not been initialized. You must set it before using Hangfire Client or Server API.

Stack Trace:

[InvalidOperationException: JobStorage.Current property value has not been initialized. You must set it before using   Hangfire Client or Server API.]
Hangfire.JobStorage.get_Current() +132
Hangfire.BackgroundJobServer..ctor() +32

Not a problem (I’ve updated the docs also):

protected void Application_Start(object sender, EventArgs e)
{
    // JobStorage.Current = new ...;

    _backgroundJobServer = new BackgroundJobServer();
    _backgroundJobServer.Start();
}

Thanks @odinserj.

Just in case if someone is wondering here is the link to documentation to initialize the JobStorage

Are you working in ASP.NET MVC? I created a blog post to install Hangfire in a non-MVC application.

Basically, you need to create a Startup.cs class like the following:

using Hangfire;
using Hangfire.SqlServer;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(YourNamespace.Startup))]
namespace YourNamespace
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            Hangfire.ConfigureHangfire(app);
            Hangfire.InitializeJobs();            
        }
    }
}

Notice the [assembly: OwinStartup(typeof(YourNamespace.Startup))] line.

@fouimette thanks for sharing all quality information. I am afraid the provided code is not supported in “Clasical” mode of IIS6.

Hi
I have similar problem. I am using OWIN, and running in ASP.NET Development Server.
Please advice. thank you
