C# Primer: A Practical Approach

7.11. Managing State: The Application Object

There is analogous support for maintaining values across sessions within the Application object. The Global class provides a skeletal definition of an Application_Start() event handler. It is invoked once at the start of the application. This is where we initialize global data for our application. For example, let's provide values to hold total mouse clicks across all sessions:
