Fixed broken references by re-installing NuGet packages.
Corrected hyperlink to EF 6.x Tools for VS in Release Notes.
Unit test Edmx_LoadRelatedEntities_Should_Populate_Multiple_Orders_With_Customer demonstrating the failure in DbContextExtensions caused by multiple EntityContainers

Result Message:	System.Data.EntitySqlException : 'Customers' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly. Near simple identifier, line 1, column 21.

DbContextExtensions fail in case of multiple containers in the workspace
Less misleading function signatures in DbContextExtensions taking parameter "Type entityType" instead of "string entityTypeName"
Find a proper EdmEntityType by the corresponding CLR type even if there are two containers with entities whos types have the same Name but different Namespaces
Created test: Apply_Changes_Should_Mark_Multiple_OrderDetails_Added
Created Test: Existing_Parent_With_Added_Children_Should_Have_Children_Marked_As_Added
Renamed acceptance test features. Created test: AddOrderDetails.
Fixed error in DbContextExtensions.ApplyChanges adding multiple child entities. Updated unit and acceptance tests.
Extend the Clone_Of_ChangeTrackingCollection_Should_Create_Deep_Copy unit test to demonstrate that the IEnumerable.Clone extension method doesn't preserve object references correctly
Fix: IEnumerable.Clone/ChangeTrackingCollection.GetChanges don't preserve object references correctly
Revert "Fix: IEnumerable.Clone/ChangeTrackingCollection.GetChanges don't preserve object references correctly"

This reverts commit 914434be6c22acf44c94ffaff8bd7133bc332ec0.
Revert "Extend the Clone_Of_ChangeTrackingCollection_Should_Create_Deep_Copy unit test to demonstrate that the IEnumerable.Clone extension method doesn't preserve object references correctly"

This reverts commit be4662bf90e31919a9dd1515d8a3967fac9e8c53.
Fixed bug in ApplyChanges with modified parent and multiple added children.
Extend the Clone_Of_ChangeTrackingCollection_Should_Create_Deep_Copy unit test to demonstrate that the IEnumerable.Clone extension method may lead to an unnecessary copy of an entity
Extend the GetChanges_On_Unchanged_Order_With_Details_Should_Return_Marked_Children unit test to demonstrate that the ChangeTrackingCollection.GetChanges method may lead to an unnecessary copy of an entity
Fix: IEnumerable.Clone/ChangeTrackingCollection.GetChanges may lead to an unnecessary copy of an entity
Corrected Customer property of mock order.
Corrected bug in last fix, which resulted in loss of partial updates based on ModifiedProperties.
