The EntityContainer name must be unique. An EntityContainer with the name 'Entities' is already defined

Question

For a little background:

I have a DLL project with the following structure:

Rivworks.Model (project)  
  \\Negotiation (folder)  
      Model.edmx          


        

Answer 1

To solve the issue Entity 6.2.0, VS 2017, single edmx

I changed the name of my model.edmx to another name, built the project, then changed it back to the original name.
