what is the global.asax Application_Start equivalent when using WAS in IIS7

问题


I'd like to use the netTcpBinding for my WCF application which is currently hosted in IIS7, which means configuring it to use WAS instead. This is fairly straight forward however, my application previously made use of the Application_Start event in the global.asax file. I do not require access to the httpContext(which I understand access has been removed in IIS7), however I would still like to hook into the start or init methods?

Does an equivalent exist when hosting an application in WAS as apposed to IIS7?

Using classic mode is not an option(again I'm not interested in the httpcontext and this only appears to work if using an http binding) - and I've seen an example of putting a static class instide the app_code folder which looks like a horrible hack.

I believe AppInitialize() is the method you're looking for. Here's an article on using it to initialise Castle Windsor in a WAS hosted WCF service:

Castle Windsor and non-HTTP Protocol WCF Services

The essence of the article is, instead of using Application_Start() which won't get called in WAS:

protected void Application_Start(object sender, EventArgs e)
{
   var container = new WindsorContainer("ioc.config");
   DefaultServiceHostFactory.RegisterContainer(container.Kernel);
}

Use:

public class InitialiseService
{
   /// <summary>
   /// Application initialisation method where we register our IOC container.
   /// </summary>
   public static void AppInitialize()
   {
      var container = new WindsorContainer("ioc.config");
      DefaultServiceHostFactory.RegisterContainer(container.Kernel);
   }
}

To quote Matt:

I confess I spent a while looking at the Host Factory in more detail, looking to wrap the DefaultServiceHostFactory. However, there appears to be a far simpler solution and that is to make use of the little documented AppInitialize method. If you create a class (any class), put it into the ASP.NET App_Code folder in your project and give it a method signature as defined below, this little baby will get fired exactly when you want it to. You can then initialise your IoC container in there.

AppInitialize is a valid method of initializing your service. But there are some other methods that might work better for you and they are described in this article: How to Initialize Hosted WCF Services
