TransactionScope and SQL Server Compact

Question

SQL Server Compact doesn't support distributed transactions. So if there are more than one connection inside TransactionScope - the exception is thrown. Is there any way to setup ADO.NET provider to use one connection for the same connection string?

I understand I can use usual transactions through connection.BeginTransaction but TransactionScope is preferable for me.

UPDATE.
Sorry, I didn't mention I work with Entity Framework, so I have no control on SQL Command. I may just pass connection string. And by some reason several connections objects created for one connection string inside TransactionScope.

Answer 1

My error was that I passed connection string to ObjectContext. If I pass connection object, only one connection is used.

Answer 2

Updated answer (code sample from here):

using (var context = new MyContext())
{
    using (var txscope = new TransactionScope())
    {
        context.Connection.Open();
        // do query 1
        // do query 2
    }
}

Update

Another solution, as you said, is to create a connection object and use it in constructors for the Object Context.
