Error adding devart entity model in vs 2019
Posted: Sun 21 Nov 2021 08:48
I am evaluating devart entity developer and have an error I don't know what to do about.
My winform c# project has to work with a MySql server, so I have installed Oracle MySql .net connector and plugin for VS.
I created a dataset in my project and have verified that I can read/write to the MySql server, so that works.
Now I want to use the Entity framework v5 and therefore installed the free version of devart entity developer.
I add 'devart entity model' to my project and goes through the wizard and choose a database first empty model.
That works well and I get the diagram designer shown in a tab in vs.
But now the problem. I get this error:
Custom tool error: A null was returned after calling the 'GetService' method on a store provider instance of type 'MySql.Data.MySqlClient.MySqlClientFactory'. The store provider might not be functioning correctly.
Do any of you know what this means ?
I use the latest version of Oracle connector and vs plugin.
