A base class that can be used to implement an in-memory cache service.

This class provides thread safe get/add methods, implements ITeamFoundationService and cleanup scheduling.

Derived class must implement a cleanup logic.

Methods

	Name	Description
	Add	Adds an item to the cache. If an item with the specified key already occurs in the cached, then new item is not added to the dictionary and the method return an item that is already in a cache.
	BulkRemove	Removes items from the cache. This method is thread safe.
	BulkSet	Adds items to the cache. If item with specified key exists in the cache, it is replaced.
	Clear	Removes all items from the cache. This method is thread safe.
	DoCleanup	This method is called to cleanup the cache. Derived class must implement cleanup strategy. A lock is acquired before this method is called, which gurantees that derived class has an exclusive access to the cache dictionary. Values are tuples, where Item1 is a stop watch that is set on a last access to the item, and Item2 is an item itself.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValues	Gets all values.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Remove	Removes an item from the cache. This method is thread safe.
	Set	Adds item to the cache. If item with specified key exists in the cache, it is replaced.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryGetValue	Gets the value associated with the specified key.

Explicit Interface Implementations

	Name	Description
	ITeamFoundationService.ServiceEnd	This method is called when the service is stopped.
	ITeamFoundationService.ServiceStart	Starts the service.
