Description Craig 2014-03-09 01:19:40 UTC
Null values are returned in sub-classed objects when using a WCF generated proxy with request/response values that uses inheritance.

Can you tell me if this bug has always existed?  Or would I be able to downgrade to a certain version of Xamarin Android where the bug doesn't exist?

Comment 3 Jonathan Pryor 2014-03-11 12:46:07 UTC
@Craig: It has likely always existed.

@Udham: Are you able to reproduce this on "desktop" Mono? I doubt this is Android-specific. Providing a simplified test case would also help.
Comment 5 Udham Singh 2014-03-11 14:35:01 UTC
I have checked this issue on windows and able to reproduce it by following the steps mentioned below:

1. Create a sample android application in VS 2013.
2. Generate the proxy using command below:

SlSvcUtil.exe https://www.vectren.com/webservices/cxf/contentService?wsdl /directory:E:\Testing\test_10__mar_2014\bug_18266\bug_18266 /n:*,Vectren.Mobile.Shared.Services.Content /o:ContentService.cs

3. Implement the code provided into bug description.
4. Debug the code for the error

Herewith I have attached the Sample Project for reference.

And when I am trying to reproduce it on "desktop" mono, not able to invoke the service method "service_getContentListCompleted".

That's because you used `slsvcutil`, which produces Silverlight-style output. Please use `svcutil` (the non-Silverlight generator) and run on Desktop mono. (The WCF backends _should_ be the same, so I'm hopeful that it'll still fail on Mono...)
