EF Team Triage: We agree that this would be a good scenario to enable. Taking into account where we are in the EF6 release along with the size and the impact of this feature our team is not planning to implement it in EF6. Therefore, we are moving it to the Future release to reconsider in the next release.

Hi EF Team,

HierarchyId it's been introduce in SQL Server 2008, How come this data type still not support in EF 6.1.

Many serious large scale applications use hierarchies for many different important business entities. The list of uses is huge. We badly need hierarchyID implemented EF.

Hi EF Team,

Has any considerations been made regarding this issue? It seems completely nuts that this feature has not yet been implemented, almost 7 years after it was introduced in SQL Server. Making developers working on this technology each having to develop their own workarounds.

Please pay attention to this issue!!!

Hi EF Team,

Please, we need EntityFramework support for HierarchyId. Someone created a small extension / fork for EntityFramework (https://www.nuget.org/packages/EntityFrameworkWithHierarchyId/) to support HierarchyId though it works to some extent but as soon as we add other packages that has dependency on EF, our app breaks.
