EntityFramework 6不适用于MySql

Question

I am trying to use my model and create a database from it. When i try to generate a database based on the model i get the following error:

Running transformation: System.InvalidOperationException: The SSDL generated by the activity called 'CsdlToSsdlAndMslActivity' is not valid and has the following errors:
No Entity Framework provider found for the ADO.NET provider with invariant name 'MySql.Data.MySqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

The following contains my App.config if that is of any help:

<?xml version="1.0" encoding="utf-8"?>

I know the issue is with the MySql.Data.MySqlClient based on the error message, but i can't seem to figure out what it wants me to do. I have added MySql.Data , MySql.Data.Entity.EF6 and EntityFramework to the project.

Anyone knows how to fix this issue?

Answer 1

I was facing the same problem before this. I manage to solve it by creating a whole new project.

1. Go to Manage NuGet Packages , install EntityFramework , MySql.ConnectorNET.Data and MySql.ConnectorNET.Entity .

2. Use the connection string as shown here <add name="SomeDatabase" providerName="MySql.Data.MySqlClient" connectionString="server=localhost;port=3306;database=example;uid=hello;password=user"/>

3. Add [DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))] in DbContext class.
