Solution that demonstrates problem

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:
Gecko/2009073022 Firefox/3.0.13 (.NET CLR 3.5.30729)

Project uses MySql Connector/NET 5.1 to connect database.

Execution of code like:
class TransTest
        const string connString =

        public bool TransactionScopeTest()
            using (TransactionScope trScope = new
                using (MySqlConnection conn = new MySqlConnection(connString))
                        conn.Open();  //Execution fails
                        MySqlCommand cmd1 = new MySqlCommand("CREATE TABLE IF
NOT EXISTS test3(f1 int, f2 int);", conn);

                        MySqlCommand cmd2 = new MySqlCommand("INSERT INTO
test3(f1,f2) VALUES (1,2)", conn);

                        return true;
                    catch (Exception ex)
                        return false;
fails with exception:
System.NotImplementedException: The requested feature is not implemented.
  at MySql.Data.MySqlClient.MySqlConnection.EnlistTransaction
(System.Transactions.Transaction transaction) [0x00000] 
  at MySql.Data.MySqlClient.MySqlConnection.Open () [0x00000] 
  at TransactionTest.TransTest.TransactionScopeTest () [0x00000] 

This exeption did not happened on Windows with Framework 2.0 when using the
same MySql Connector/NET 5.1

Reproducible: Always

The same Connector and SQL code works fine with CommittableTransaction Class,
see attachment.
