Question

I have DTC configured as outlined on MS website to support for remote transaction. I have the following code always giving me error.

using (TransactionScope ts = new TransactionScope())
{
   Category c = new Category();
   c.Name = "Cat1";
   c.Save();

   Product p = Product.SingleOrDefault(x=>x.ProductID==1);
   p.Title = "new title";
   p.Save();

   ts.Close();
 }

However if I move the second block of code out of the suing block it works just fine. What I want to do is bind those two block of code into one trascation. What could be the readon? Thanks,

You don’t specify what error the code is giving you but the only thing wrong I can see is that you’re not calling Complete on your TransactionScope. Try the following:

using (TransactionScope ts = new TransactionScope())
{
   Category c = new Category();
   c.Name = "Cat1";
   c.Save();

   Product p = Product.SingleOrDefault(x=>x.ProductID==1);
   p.Title = "new title";
   p.Save();

   ts.Complete();
 }

You shouldn’t actually need DTC enabled, you can wrap this code in a transaction using SubSonic’s SharedDbConnectionScope. Try the following:

using (TransactionScope ts = new TransactionScope())
using (SharedDbConnectionScope sharedConnectionScope = new SharedDbConnectionScope())
{
   Category c = new Category();
   c.Name = "Cat1";
   c.Save();

   Product p = Product.SingleOrDefault(x=>x.ProductID==1);
   p.Title = "new title";
   p.Save();

   ts.Complete();
 }
