Check out the new ManagedESENT documentation on MSDN at http://msdn.microsoft.com/en-us/library/windows/desktop/dn375980(v=exchg.10).aspx. This documentation covers over 300 public methods exposed by ManagedESENT.
How is the ManagedESENT library different than ESENT?
ESENT is an embeddable, transactional database engine that allows you to create custom applications that need reliable, high-performance, low-overhead storage of data. The ESENT engine can help with data needs that range from something as simple as a hash table that is too large to store in memory, to something more complex, such as an application with tables, columns, and indexes. To create an application with ESENT, you use the esent.dll DLL that is part of the Windows operating system and write your code with C/C++. For more information about ESENT, see Extensible Storage Engine Reference.
ManagedESENT is built on top of esent.dll, which is part of Windows, so there are no extra unmanaged binaries to download and install. With the ManagedESENT library, you can create your application by using a managed language such as C# instead of C/C++. The library uses the same type and member names to expose the ESE API, so if you are already familiar with the structure of this API, you can easily transition to this managed library.
