Hello Erik, You are right, the old approach - with an object scope provider, requires the transactions to be handled manually. However, with the introduction of the new API, this is no longer needed. When you create a domain context, a new transaction starts automatically. To commit the transaction, simply call context.SaveChanges( ). This will save your changes and start a new transaction. If you want to revert the changes, call DataContext.ClearChanges() instead. I hope this answers your question. Please do not hesitate to contact us if you need more help.

Hi,

maybe a double post, but regarding Open Access I'm always asking myself if I'm reading a post or a blog on the old or the new way... the doc and blogs are not dated so that makes it that much harder...

I'm having some general questions regarding Open Access, latest version Q2 2011. I'll post them separately.

Q:how do I handle transactions? I se some examples using a scopeprovider, but I thought this was the old way, I'm using a context. but my context and scope give me an error saying that I can't start a transaction because the connnection is "managed".

regards,

Erik
