Multiple databases(datacontext) on same server without MS DTC RRS feed

  • Question

  • I'm using EF5.0 with SQL server 2008. I have two databases on the same server instance. I need to update tables on both databases and want them to be same transaction. So I used the TransactionScope. Below is the code -

      public void Save()
                var MSObjectContext = ((IObjectContextAdapter)MSDataContext).ObjectContext;
                var AWObjectContext = ((IObjectContextAdapter)AwContext).ObjectContext;
                using (var scope = new TransactionScope(TransactionScopeOption.Required,
                                                     new TransactionOptions
                                                             IsolationLevel = IsolationLevel.ReadUncommitted

    When I use the above code Transaction gets promoted to DTC. After searching on internet I found that this happens because of two different connectionstrings / connections. But what I dont understand is if I write a stored procedure on one database which updates table in a different database (on same server) no DTC is required. Then why EF or TransactionScope is promoting this to DTC? Is there any other work around for this?

    Please advise

    Thanks in advance
