The Host property is intended for use by .NET Framework host environments and by cache implementations that implement behavior that depends on the .NET Framework host environment.

The following table lists the set of host environment services that might be available from a managed hosting environment and that are available to ObjectCache implementations through the Host property:




Lets host environments provide application domain identifiers that might be needed by a cache implementation for features such as identifying performance counters.


Lets host environments provide a custom file-change notification system, instead of using the one provided in the .NET Framework.


Lets cache implementations report cache memory consumption to the host environment. This enables host environments to centrally manage memory consumption across multiple cache implementations.
