Xamarin表单，使用WCF服务错误

Question

Currently I have Xamarin.Forms application which use service reference WCF, SellerCloud API which is on " http://ws.timezone123.com/SCService.asmx ".

Referencing SCService I receive two compile exceptions "The type or namespace name 'XmlElement' does not exist in the namespace 'System.Xml' (are you missing an assembly reference?)" and "The type or namespace name 'schema' could not be found (are you missing a using directive or an assembly reference?)".

http://prntscr.com/g5sgf1

Currently library, from which I am trying to reference service is Portal Class Library with Target Framework "Profile7".

Can you suggest what I can do in that case to make it work?

Thanks

How did you add the service reference to PCL?

You are trying to consume ASMX web service( XML web service with SOAP protocol). As i can see your screenshot ,you added a connected service (typically used for azure app services) not a Web reference . In order to consume ASMX service you need to add a Web reference .

Problem is, web reference is not available in PCL .But it is available in platform specific projects(right click the droid or Ios project --->Add--->Web Reference).

If you add web reference correctly it will generate proxies within your platform specif projects.Then you need to access generated web methods through Dependency service in your PCL.Please check following documentation for further idea

Following question is some what similar to your problem

Is there any supported way to call asmx web services from cross-platform Xamarin code?
