You access and retrieve the Application key/values with the

Application["MyObjectName"]

syntax. You need to cast to the appropriate type as needed.

In the Application_Start you need to create a new reference to your security object that will be stored in the Application key/value called something like "Security". Then when you access the object, you will need to cast it to the security type.

Try this:

Application_Start

Application["Security"] = new KirtlandAssociates.Web.WebSecurity.Security();

To Access the key/value use

KirtlandAssociates.Web.WebSecurity.Security security = (KirtlandAssociates.Web.WebSecurity.Security)Application["Security"];
