Prerequisites

• I have written a descriptive issue title
• I have verified that I am running the latest version of the SysML2.NET
• I have searched open and closed issues to ensure it has not already been reported

Description

When synchronizing the DAL cache, extensions method that update references uses class type as target type instead of interface ones.

Since inheritance is only performed via interface, casting at runtime may fail due to that reason.

The handlebars template has to be updated to always use interfaces type and regenerate

Steps to Reproduce
