Syntax
public class InMemoryManager : BaseAsyncSafeConnector, IUpdateableStorage, IQueryableStorage, IStorageProvider, IAsyncUpdateableStorage, IAsyncQueryableStorage, IAsyncStorageProvider, IStorageCapabilities, IDisposable, IConfigurationSerializable
Remarks

Useful if you want to test out some code using temporary in-memory data before you run the code against a real store or if you are using some code that requires an IStorageProvider interface but you need the results of that code to be available directly in-memory.
