Increase performance of Importing Entities (and related actions)

I've ran into quite a bit of performance issues when importing entities between Entity Managers. The main bottleneck seems to be the deep cloning of the EntityCacheState which uses the DataContractSerializer. This ends up being a pretty heavyweight step if you only need to move a coupe of entities to a new Entity Manager.

There have been other performance problems related to this same behavior.

See the following forum thread for more details: http://www.ideablade.com/forum/forum_posts.asp?TID=3978&KW=&PID=15842&title=performance-issues-with-importentities

The 7.2 releases improves performance when calling EntityManager.ImportEntities, and of the EntityCacheState when calling CacheStateManager.GetCacheState, RestoreCacheState and Merge.

This improvement is due to a change in the “deep cloning” methodology used by DevForce, and also affects 2-tier EntityManager.SaveChanges calls. [F2137]

This change may be breaking to some applications; see the Breaking Changes section of the release notes for more info:

    We are still on 2010 and might not be upgrading for a little while so we'd vote for the changes to make their way back to 2010. Thanks!

    We've addressed this in the coming release of DevForce 2012. We may back port to DevForce 2010 if there's enough demand.
