描述:Service端的抽象类在客户端可以编译通过.‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
还有我在Service端加的注释不能在Client端显示,如何为Service端的类添加注释以辅助客户端使用Service呢?‡vډ»Äùøwww.netcsharp.cn:<åƒažõ

可以說,Known完全是SOA與OO沖突的產物,是個可憐的棄子!OO要求繼承父類的東西,但SOA不知道是否把繼承的東西Show給Client.最后WCF決定子類不Show給Client.從而導致了繼承和多態在WCF的丟失,為了彌補這個問題,Known Attribute就產生了.‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
Known標志著子類可被客戶端識別、使用.‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
可以使用Known的三個地方‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
一.基類自身‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
二.特定操作‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
三.服務契約‡vډ»Äùøwww.netcsharp.cn:<åƒažõ
