The ObjectCache type is the primary type for the in-memory object cache. To develop a custom cache implementation, you derive from the ObjectCache class.

System_CAPS_noteNote

The ObjectCache class is new as of the .NET Framework 4.

The built-in MemoryCache class derives from the ObjectCache class. The MemoryCache class is the only concrete object cache implementation in the .NET Framework 4 that derives from the ObjectCache class.

Notes to Inheritors:

Because the ObjectCache type represents only common cache functions, there is no requirement for how an ObjectCache instance must be instantiated and obtained. In addition, there is no requirement that concrete implementations of the ObjectCache class must be singletons.

System_CAPS_noteNote

MemoryCache is not a singleton, but you should create only a few or potentially only one MemoryCache instance and code that caches items should use those instances.

When you inherit from the ObjectCache class, you must override its methods.

System_CAPS_importantImportant

All implementations of the ObjectCache class should disallow null as a value for cached data. This helps avoid confusion between null as a data value and a cache entry that was not found.

.NET Framework
Available since 4.0

This type is thread safe.
