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 开发者_JAVA百科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.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.
More information about when Entities opens new connection.
My error was that I passed connection string to ObjectContext
. If I pass connection object, only one connection is used.
