ManagedEsent provides managed access to esent.dll, the embeddable database engine native to Windows.

The Microsoft.Isam.Esent.Interop namespace in EsentInterop.dll provides managed access to the basic ESENT API. Use this for applications that want access to the full ESENT feature set.

The PersistentDictionary class in EsentCollections.dll provides a persistent, generic dictionary for .NET, with LINQ support. A PersistentDictionary is backed by an ESENT database and can be used to replace a standard Dictionary, HashTable, or SortedList. Use it when you want extremely simple, reliable and fast data persistence.

esedb provides both dbm and shelve modules built on top of ESENT IronPython users.
