SQL Scripts from dotnet with transactions

I have been trying to execute sql scripts from dotnet (C#) but the sql scripts could contain GO statements and I would like to be able to wrap the collection of scripts in a transaction.

I found this question and the accepted answer got me going for handling the GO statements, but if I use a BeginTransaction it throws a InvalidOperationException at the "new ServerConnection" line.

SqlConnection connection = new SqlConnection(connectionString);
connection.Open();
SqlTransaction transaction = connection.BeginTransaction(transactionName);
ServerConnection serverConnection = new ServerConnection(connection);

I am running this against a SQL 2005 server.

I found a way, after trying several combinations, the simplest one worked...

Well this is assuming you are using a TransactionScope object

using (
    var transactionScope = new TransactionScope(TransactionScopeOption.Required,
                                                new TransactionOptions
                                                    {
                                                        IsolationLevel =
                                                            IsolationLevel.ReadCommitted,
                                                        Timeout = TimeSpan.FromMinutes(300)
                                                    }))
{
    sqlServerInstance.ConnectionContext.SqlExecutionModes = SqlExecutionModes.ExecuteAndCaptureSql;
    sqlServerInstance.ConnectionContext.StatementTimeout = int.MaxValue;

    //This line makes the MAGIC happen =)
    sqlServerInstance.ConnectionContext.SqlConnectionObject.EnlistTransaction(Transaction.Current);
    sqlServerInstance.ConnectionContext.ExecuteNonQuery(scriptContent);
}

Try using the BeginTransaction and CommitTransaction methods on the ServerConnection instance instead. I use this without any problems.

Try starting the transaction after you've attached the ServerConnection to the SqlConnection's settings.

Also, what are you using ServerConnection for that you can't do from SqlConnection?
