AppDomainLoad

AppDomainLoad is a .NET Framework concept that refers to the process of loading an assembly into a specific application domain. An application domain, or AppDomain, is an isolation boundary within a process. Each AppDomain has its own set of security policies, loaded assemblies, and execution context. When an assembly is loaded into an AppDomain, it becomes accessible and executable within that domain.

This isolation provided by AppDomains offers several benefits. It allows for different security policies to be applied to different parts of an application, preventing untrusted code from accessing sensitive resources. It also enables assemblies to be unloaded from an AppDomain without affecting other parts of the application, which is useful for scenarios like plugin architectures or hot-swapping code.

The AppDomainLoad event is a notification that occurs when an assembly is loaded into an application domain. This event can be useful for implementing custom logic related to assembly loading, such as logging, performing additional security checks, or modifying the loaded assembly in some way. Developers can register event handlers to respond to AppDomainLoad events, allowing them to gain insight into and control over the assembly loading process. Understanding AppDomainLoad is crucial for managing the lifecycle and security of .NET applications, particularly in complex or extensible environments.
