How to automatically install Application Initialization in Azure Web Role SDK v1 8

Question

I see that Application Initialization as a feature of the web server role is not enabled. How I can enable this from a start-up script? I'm not sure how to add a server role feature.

Answer 1

Follow these steps -

• Install the feature using a startup task:

PKGMGR.EXE /iu:IIS-ApplicationInit

• Configure your site in IIS (startMode and preloadEnabled):

public class WebRole : RoleEntryPoint
{
    public override void Run()
    {
        using (var serverManager = new ServerManager())
        {
            var mainSite = serverManager.Sites[RoleEnvironment.CurrentRoleInstance.Id + "_Web"];
            var mainApplication = mainSite.Applications["/"];
            mainApplication["preloadEnabled"] = true;

            var mainApplicationPool = serverManager.ApplicationPools[mainApplication.ApplicationPoolName];
            mainApplicationPool["startMode"] = "AlwaysRunning";

            serverManager.CommitChanges();
        }

        base.Run();
    }

    public override bool OnStart()
    {
        // For information on handling configuration changes
        // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.

        return base.OnStart();
    }
}
