It seems that using svcutil will not generate the TransactionFlow attribute.
Looking at the generated class, we see that it is missing.
Is there a fix for this ?
EDIT: more info, I'm running svcutil against a dll to get the metadata and then run svcutil /t:code against that metadata for code generatino.
I've notice that running against a live wcf service, it actually generates the transactionflow attribute the live wcf service has wshttpbinding. But against an assembly, the attribute is not generated.
