entity framework - Add a DbProviderFactory without an App.Config

Question

I am using DbProviderFactories in my data layer (based on Entity Framework) and am using SQLite for my database, but I don't have to have a App.Config to have the following code:

<configuration>
  <system.data>
    <DbProviderFactories>
      <remove invariant="System.Data.SQLite"/>
      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
    </DbProviderFactories>
  </system.data>
</configuration>

Instead I would like to have my data layer put that in programmatically. Anyone know a way to do this?

EDIT:

The reason for this is that I am using a IoC container to pick the data layer and some of my data layers don't need the App.Config values, or have them be hard tied to the data layer.

Answer 1

The following will probably cause sunspots and overthrow western civilization. It may even cause a debate about Duct Tape Programming (make it stop!), but it works (for now)

try
{
    var dataSet = ConfigurationManager.GetSection("system.data") as System.Data.DataSet;
    dataSet.Tables[0].Rows.Add("SQLite Data Provider"
    , ".Net Framework Data Provider for SQLite"
    , "System.Data.SQLite"
    , "System.Data.SQLite.SQLiteFactory, System.Data.SQLite");
}
catch (System.Data.ConstraintException) { }
