Problems connecting ASP.NET MVC3 website to MySQL

Question

I'm having problems connecting my website (asp.net mvc3) to MySQL.

Localhost is working, but on the server I receive the following error:

Error: Unable to locate the Data Provider. Requested Net Framework. Maybe it is not installed.

Stacktrace: [ArgumentException: The repository provider specified is not found in the configuration or is not valid.]

I'm using Mysql.connector 6.6.5.0 and EntityFramework 5.0.

My connectionstring:

  <connectionStrings>
    <add name="MyEntities" connectionString="metadata=res://*/Models.Model.csdl|res://*/Models.Model.ssdl|res://*/Models.Model.msl;provider=MySql.Data.MySqlClient;provider connection string=&quot;server=[HOST];user id=[USER]; password=[PASSWORD]; database=[DATABASE]&quot;" providerName="System.Data.EntityClient"/>   </connectionStrings>

Answer 1

I resolved.

Just put the provider dlls in the bin folder and do the setting in Web.config:

  <system.data>
    <DbProviderFactories>
      <clear />
      <remove invariant="MySQL Data Provider"/>
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.6.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />     
    </DbProviderFactories>   </system.data>

Just remember to change the provider version.

You can also tell the compiler to copy these files in the bin directory, by setting "Copy Local" to True :
