I have created a WCF service that retrieves data from SQL database and can update and modify data into SQL database. I am trying to call WCF methods from xamarin for android and xamarin for iOS. I searched alot for an example how to call PUT and POST method from WCF service through xamarin for android and xamarin for iOS but no luck. I have added the WCF code below for reference. ...even created Web API but all examples and tutorials to consume Web API are for how to call GET method . I don't see any reference document which will show how to call PUT or Post method from WCF or Web api across cross platform. I have tested WCF service through Fiddler and worked fine. What would be the next step ..I have created proxy for this web service using SlsvcUtil.exe as mentioned in xamarin documentation. Can somebody post a one example of xamarin.Android that will call Update or delete method from the below wcf service.Desperately looking for help.Service contains webHttp binding.
