Question 137. What Is The Difference Between An Application Domain And A Process?
An application domain is lighter than a process. Application domains are appropriate for scenarios that require isolation without the heavy cost associated with running an application within a process. A process runs exactly one application. In contrast, the CLR allows multiple applications to be run in a single process by loading them into separate application domains. Additionally, the CLR verifies that user code in an application domain is type safe.
