Parameters

enableSession

transactionOption

Initializes the transaction support of an XML Web service method.

cacheDuration

Initializes the number of seconds the response is cached.

bufferResponse

Initializes whether the response for this request is buffered.

A web service call can only be the root of a transaction, due to the stateless nature of the HTTP protocol. This means that the following two settings are equivalent, with each call creating a new transaction:

[WebMethod(TransactionOption = TransactionOption.Required)]
[WebMethod(TransactionOption = TransactionOption.RequiresNew)]

It also means that all the following settings are equivalent; meaning no transaction support:

[WebMethod] // TransactionOption.Disabled is the default
[WebMethod(TransactionOption = TransactionOption.Disabled)]
[WebMethod(TransactionOption = Transaction.NotSupported)]
[WebMethod(TransactionOption = Transaction.Supported)]
