Enity Framework With MySQL

Question

I am getting the following error

\"The Entity Framework provider type \'MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity\' registered in the applicati

Answer 1

for anyone facing the same problem, here is the line that causes the Exception is this

<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity" />

Just append .EF6 to MySql.Data.Entity such that the provider is like this

<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />

As such your choice to remove the code within didn't help solve the problem. I hope this helps someone.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <connectionStrings>
    <add name="inspectm_inspectContext" connectionString="server=--;user id=--;password=--;database=--;persistsecurityinfo=True" providerName="MySql.Data.MySqlClient" />
  </connectionStrings>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
     <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
     </providers>
  </entityFramework>
</configuration>

My Complete App.conf this worked for me

First I removed

<DbProviderFactories>
<add name="MySQL Data Provider"
invariant="MySql.Data.MySqlClient"
description=".Net Framework Data Provider for MySQL"
type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.7.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>

Then I changed

<defaultConnectionFactory type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />

And Added the provider

<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>

You Could Also Do the Following

[DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))]
public class DemoContext : DbContext{}
{

Answer 4

Check for an inner exception.

I get

{"Inheritance security rules violated by type: 'MySql.Data.Entity.MySqlEFConfiguration'. Derived types must either match the security accessibility of the base type or be less accessible.":"MySql.Data.Entity.MySqlEFConfiguration"}

That points me to: Inheritance security rules violated by type: 'MySql.Data.Entity.MySqlEFConfiguration'

I dont really like to downgrade. But so far i haven't found a better answer.
