Failed to find or load the registered .Net Framework Data Provider

Posted by Blake on 12/12/2010

Tonight I was trying to setup and use the ASP.NET GridView with the MySql Connector to allow for easy editing of code table for a site I'm creating. The framework I'm going against for this project is the .Net Framework 4.0 (I downloaded the source code for the MySql connector and I compiled against 4.0 so I would have a native library that didn't have to also have 3.5 present).

Anyway, the above error is fixed by adding the following to the web.config:

    <remove invariant="MySql.Data.MySqlClient" />
    <add name="MySql Data Provider" invariant="MySql.Data.MySqlClient"
         description=".Net Framework Data Provider for MySql"
         type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />

For reference, the bones of the SqlDataSource in the ASP.Net markup looks something like this:

    <asp:SqlDataSource ID="dsMySql" runat="server"
                       ConnectionString="<%$ ConnectionStrings:MySqlMain%>"
                       ProviderName="<%$ ConnectionStrings:MySqlMain.ProviderName%>"
