Managing Application and Session State in ASP.NET C#
Implementing Application State Management in ASP.NET
This document analyzes C# code snippets demonstrating how to manage a shared counter across an entire ASP.NET application using the Application state object. The implementation is split between the default page logic (_default.aspx.cs) and the global application logic (Global.asax.cs).
The Default Page Logic (_default.aspx.cs)
This partial class, located within the AulaIV namespace, handles user interactions and displays the current application count.
