DomainService的[Invoke(HasSideEffects=true)]该怎么理解？

[namhyuk]

MSDN上的解释是：Operations with side effects may be invoked in different ways by consumers of a DomainService. For example, clients that invoke a DomainService over HTTP may use POST requests for invoke operations with side effects, whereas GET may be used otherwise.


在Business App模板的UserRegistrationService的CreateUser()方法用[Invoke(HasSideEffects=true)]这个修饰的。

使用起来有什么差别吗？

是不是用了这个才会自动生成ValidationErrors?
