Silverlight 调用 RIA Service

今天给一个Silverlight的项目做后台，发现了几个选择，WCF RIA service，Web service，还有Ado data service，选了第一个，微软的东西名字一个一个，真是麻烦。

上网找了些资料，大部分都是Help里那个例子的翻译，汗一个。微软的例子总是用他自己那些wizard，而且搭上一个adonet的datasource，看得我非常不爽。因为我nhibernate层已经写完了。

然后发现RIA服务是异步的，建立一个Silverlight项目后会生成一个sl的app个sl的web，

往里面加一个ria服务的class library项目，又多了两个项目，ria 类库项目和ria web项目。

然后SL的web应用ria的web，sl的app引用ria的类库。依赖关系就建立好了。

结构如下。

RIA类库的行为比较怪异，为了给客户端用，可以发现上图有一个Generated_Code的文件夹，

里面是ria web里生成的代码。

我们做的事情都在Domainservice1这个文件里，做一个方法，编译一下，会生成一些相应的代码给SL用。

Domainservice1的代码如下。

SL调用里一个方法被我注释掉了。

因为今天发现得到model的时候必须有【query】这个标记。

貌似没有这个标记，可以得到model，但是修改后commit回去的时候不会调用update的方法。

今天是第一天做Silverlight，希望这几天能有跟多发现。
