Entity Framework 6 problem

Post by colm » Wed 04 Dec 2013 23:03

I tried following the steps here:http://www.devart.com/dotconnect/postgr ... html#model

But at the very end of the process, I get this error message:
"Your project references the latest version of Entity Framework; however, an Entity Framework database provider compatible with this version could not be found for your data connection. Exit this wizard, install a compatible driver, and rebuild your project before performing this action"

My app.config contains provider version 7.1.45.6.
I get the version by right clicking on Devart.Data.PostgreSql.Entity.dll under
C:\Program Files (x86)\Devart\dotConnect\PostgreSQL\Entity\EF6

Given that I had the above problem, I tried the "Devart Entity Model" and got on quite well with it. I am very happy so far actually...

So my question is: Is there any difference in using the Devart Entity Model, versus the "ADO.Net Entity Model" approach? Is Devart Entity Model essentially the same thing?

Thank you

We recommend you to use Entity Developer (Devart Entity Model, *.edml) instead of EDM Designer (ADO.NET Entity Data Model, *.edmx) because it is adjusted for working with PostgreSQL and has an advanced functionality: http://www.devart.com/entitydeveloper/ed-vs-edm.html.

Entity Developer adds registration of EF-provider in app.config automatically. With EDM Designer, you should add registration manually: http://blog.devart.com/entity-framework ... force.html.
