Create a class instance on Application_Start

Is it possible to create a class instance on Application_Start that can be used in all controllers?

I would like to be able to create for example:

var globalHelper = new LoadsStuff();

and then in my Action methods: 

globalHelper.GetInfoFor("key");

My Helper class loads a fairly big XML file to memory and I would like to do that only once.

Use application variables:

Application["GlobalHelper"] = new LoadsStuff();

((LoadsStuff) Application["GlobalHelper"]).GetInfoFor("key");

Refer to:

Yes I think you can. I have not tried this, but something like:

ManagedWebSessionContext.Bind(HttpContext.Current, globalHelper)

What if you put your XML file Application level object in Application_Start event ?

void Application_Start(object sender, EventArgs e)
{
     Application[""] = //
}
