[Mono-dev] Problem in SvcHttpHandler.cs ?

[Alan McGovern]

The reason why there are no synchronous calls in silverlight is (I  
believe) because you can easily deadlock the plugin by attempting a  
synchronous call when using the browser http stack. For the web  
request to be completed, the browser has to be able to iterate and if  
a plugin is blocking, there's nothing the browser can do.

If I remeber correctly there is an explanation of this on msdn  
somewhere.
