GraphDiff

DbContext extension methods for Entity Framework Code First, that allow you to save an entire detached Model/Entity, with child Entities and Lists, to the database without writing the code to do it.

This version is for EF6+. If you would like to use the project on EF(4.3,5.0) see this branch https://github.com/refactorthis/GraphDiff/tree/EF4-5.

Please see the initial post @ http://blog.brentmckendrick.com/introducing-graphdiff-for-entity-framework-code-first-allowing-automated-updates-of-a-graph-of-detached-entities/ for more information.

Nuget package is at http://nuget.org/packages/RefactorThis.GraphDiff/

Features

Merge an entire graph of detached entities to the database using DbContext.UpdateGraph();
Ensures concurrency is maintained for all child entities in the graph
Allows for different configuration mappings to ensure that only changes within the defined graph are persisted
Comprehensive testing suite to cover many (un/)common scenarios.

Proposed Features

Fluent API style mapping of aggregates on bootstrapping
Retrieve an aggregate from the database without specifying include expressions
Define the aggregate using attributes on the models
Allow for the initial db query to be performed as multiple queries where needed (too many includes, etc)

Release Notes

2.0.1

Rewrite of graph traversal code and rewrite of tests to cover more scenarios.
