Hi,

In some scenarios in my Silverlight application, I need to use transactions on server side. I noticed that the transaction is promoted to Distributed Transaction when querying or saving (almost with a unique EntitityManager).

I understand that for scalability reasons and multi-server environments this is necessary.

Is there any options to set to avoid this to happen ?

Unfortunately Windows Azure platform doesn’t support distributed transactions !


Regards

We'll have to look into why the promotion is occurring.   
 
DevForce will by default create a TransactionScope for a query or save, but you can turn this off by setting "UseTransactionScope=false" on the TransactionSettings associated with the QueryStrategy or SaveOptions.   Since you've already opened your own TransactionScope, there's really no need for the inner scope used by DevForce anyway.

Hi,

Any news about why the DTC promotion is occuring ? and how to avoid it (UseTransactionScop = false doesn't change anything).

Regards
