ESRI已推出for silverlight api的beta版，这让我们的开发又多了一种选择：
javascript api
flex api
silverlight api
========
java api
.net api
引用James Fee blog上一句话：Looks simple enough to leverage and I’m guessing since Microsoftdevelopers are in love with Silverlight, it won’t be long before theJSAPI is pushed aside.
最直接的感受就是比javascript和flex api的地图要平滑许多。相信RIA在silverlight上会有更好的表现。和flex要一较高下了
enjoy~~~
vista系统之外要安装silverlight插件，和flash一样，装吧
