Application Domain

An Application Domain is a light weight process and provides a logical and physical isolation from another .NET application.

• This ensures that the Applications can work independent and isolated of each other. An Application Domain is created by the Common Language Runtime (CLR) and it ensures that if one Application Domain crashes or goes down, it does not in any way effect the functioning of another Application Domain.
• Multiple .NET applications can be executed in one single process by loading these applications in separate Application Domains.
• Several threads can be executing in a single application domain at any given time and a particular thread is not confined to a single application domain. In other words, threads are free to cross application domain boundaries and a new thread is not created for each application domain.
• The following are the benefits of Application Domains.
  Isolation of code, data and configuration information of one application from another
  A failure in one application will not affect the other
