Unable to get result set shape for PROCEDURE 'dbo.Department_Delete'

Describe what is not working as expected.

Steps to reproduce

1. Create database from this script: https://gist.githubusercontent.com/doggy8088/2a2f7075d49b3814d19513426ede3549/raw/56926225027def21c627dd6391ab4866957ca5ac/ContosoUniversity.sql

2. Create new project and use Reverse Engineer to generate classes including all Stored Procedures.

3. You will see errors in the Output window.

@mustafaelshobaky please don’t add to closed issues.

This error was always there, it was just not communicated back previously.

You will have to refactor your stored proc in create the result set shape yourself as described in the wiki.
