Hi,
IDS 11.5 does not seem to have no GUID data type compatible with Microsoft Entity Framework. Does anyone know if it exist in the new 11.7 version?

If not, I found this article: Using GUIDs with IDS 9.x
that describes with code how to create a GUID datatype in the database. It works grate. The problem is however that Microsoft Entity Framework (EF) does not recognise it as a valid GUID data type. Is it possible to extend it such that it becomes recognizable by EF?
