I have a question about a process class in MM.NET. We are using the EntityFramework along with MM.NET in a process class. The process method is making changes to several tables. We want to wrap the changes in a transaction. The only way we can find to do this is something like this:

var biz1 = new somebizobject();
var biz2 = new someotherbizobject();
var transaction = biz1.ObjectContext.Connection.BeginTransaction()

…do something using the business objects…

if (success) transaction.Commit()
else transaction.Rollback()

On the BeginTransaction call we get an error message saying the connection is not open.

So how do we do this?
