It is an isolation layer provided by the .NET runtime. As such, App domains live with in a process (1 process can have many app domains) and have their own virtual address space.
App domains are useful because:
- They are less expensive than full processes
- They are multithreaded
- You can stop one without killing everything in the process
- Segregation of resources/config/etc
- Each app domain runs on its own security level
