An item with the same key has already been added. #108

Job Message: Main Message: An item with the same key has already been added. Main Message Stack Trace: at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary2.Insert(TKey key, TValue value, Boolean add) at EntityFramework.Utilities.EfMappingFactory.GetMappingsForContext(DbContext context) at EntityFramework.Utilities.EFBatchOperation2 .InsertAll[TEntity](IEnumerable1 items, DbConnection connection, Nullable1 batchSize)

This error occurs intermittently, though no duplicate key is being passed to the InsertAll().

+1 An item with the same key has already been added. at System.Collections.Generic.Dictionary2.Insert(TKey key, TValue value, Boolean add) at EntityFramework.Utilities.EFBatchOperation2.InsertAll[TEntity](IEnumerable1 items, DbConnection connection, Nullable1 batchSize)

Does anyone have any idea what might be causing this?

I actually stopped usinf this utility. If you loop and add is still good. Didnt see any performance issues. Just do your own.

+1 getting the followin stack trace when apparently trying to insert an empty collection:

System.ArgumentException: An item with the same key has already been added. at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary``2.Insert(TKey key, TValue value, Boolean add) at EntityFramework.Utilities.EfMappingFactory.GetMappingsForContext(DbContext context) in D:\Projects\GSAP-X-API\src\Externals\EntityFramework.Utilities\MappingHelper.cs:line 312 at EntityFramework.Utilities.EFBatchOperation``2.InsertAll[TEntity](IEnumerable``1 items, DbConnection connection, Nullable``1 batchSize) in D:\Projects\GSAP-X-API\src\Externals\EntityFramework.Utilities\EFBatchOperation.cs:line 115

I couldn't reproduce the issue using integration tests. My current versions are:

EntityFramework = 6.1.3 EntityFramework.Utilities = 1.0.2.0

See #57. This is a concurrency issue that would have been fixed if #61 or #113 ever got merged. Unfortunately, this project hasn't been updated in a while. Check out my fork, it contains all the latest fixes.
