The AppIsolated property indicates whether an application is to run in-process, out-of-process, or in a pooled-process. A value of 0 indicates that the application is to run in-process, a value of 1 indicates out-of-process, and a value of 2 indicates a pooled-process. Use the application management methods of the IIsWebVirtualDir and IIsWebDirectory objects to set the process space for your application.
Because this property is internally configured by IIS, you should consider it to be read-only. Do not configure this property.
You can configure this property at the following locations in the IIS metabase.
