You could use the following as well. I wanted to inject some Dapper.NET into a existing project that already had Entity framework entity context so I created the following:

public class EFConnectionAccessor : IDisposable
{
    private readonly SqlConnection sqlConnection;
    private readonly MyEntities entities;

    public EFConnectionAccessor()
    {
        entities = new MyEntities();

        var entityConnection = entities.Connection as EntityConnection;

        if (entityConnection != null)
        {
            sqlConnection = entityConnection.StoreConnection as SqlConnection;
        }
    }

    public SqlConnection connection
    {
        get
        {
            sqlConnection.Open();
            return sqlConnection;
        }
    }

    public void Dispose()
    {
        sqlConnection.Close();
        sqlConnection.Dispose();
        entities.Dispose();
    }
}

Called using

using (SqlConnection sqlConnection = new EFConnectionAccessor().connection)
{
 // ADO.NET CODE HERE - Or in my case dapper.net
}
