<pre>环境:客户端:Silverlight4,服务端(.netfx 4.0,wcf)</pre>
<pre>这个系统是提供给企业内部使用的,我希望系统能自动根据运行环境来选择通过http或者tcp来访问wcf服务.</pre>
<pre>如果允许在浏览器中,使用basichttpbinding,如果在浏览器外运行,则使用tcpnetbinding,以获得更好的性能.</pre>
<pre>我在Silverlight中首先添加了http绑定的wcf服务,然后手工修改配置文件.</pre>
<pre>在配置文件中添加了Tcpnet绑定的内容,希望两个服务可以共用一个Contact.终结点的配置如下: </pre>

</div>
<p> </p>
然后在代码中这样获取服务,这是个服务工厂,对于使用者是透明的: </pre>

</div>
<p> </p>
结果发现,在浏览器中运行使用http绑定都是正常的,而在浏览器外使用tcp下,无法工作.请教,自动选择服务绑定的思路是否可行,我该如何做. </pre>
<pre>附:如果在添加服务的时候,添加的是tcp绑定的服务,然后在配置文件中添加http绑定,结果是反过来,tcp可用,而http不可用.</pre>
<pre>如果同时添加两种服务,那么两个服务的名称空间不一致,无法实现服务工厂.</pre>
