I can't add SOAP web services into my project.

Hi Team,

I am working on xamarin forms pcl project. I need to add magento SOAP API into my project. I tried to add web reference to the wsdl file, but no luck.
This is the breaking point of my project. Please respond. Thank you.
Refer the below link for API definition.
