سؤال
If I want to store some Objects to share across pages and session which one should I use?
HttpContext.Current.ApplicationInstance.Application
or HttpContext.Current.Application
.
I was using HttpContext.Current.Application
but just got confused between the two.

Application
and ApplicationInstance.Application
are two versions of the same HttpApplicationState object.
From the HttpApplicationState reference:
A single instance of an HttpApplicationState class is created the first time a client requests any URL resource from within a particular ASP.NET application virtual directory. A separate single instance is created for each ASP.NET application on a Web server. A reference to each instance is then exposed via the intrinsic Application object.
To summarize:
Application
object is global to the web server.ApplicationInstance.Application
object is local to the application the request refers to. (e.g. site or virtual directory application)
This is further explained in this blog post.
