Windows Phone 8.1 and Backendless 4.0

Windows Phone/.NET
1

Hi,

I migrated my Windows Phone project from version 3.0 to 4.0 and in my cllient app I changed the application Id to new 4.0 project. After that when i call Backendless.UserService.Login method, I got error 2002 Version is disabled or provided wrong application info (application id or secret key).
I am trying to find the latest dll for Windows Phone 8.1, but without success. Can you help me, please?
Thanks!

Hi Michal,

Have you updated the project to use the latest build of our SDK for .NET? Also, have you changed the API key?

Mark

I haven’t changed API key, because, API key is the same in both versions.

Where I find latest SDK for Windows Phone 8? I found this one https://github.com/Backendless/.NET-SDK, but folder Backendless/Bin/WP8 is empty and folder Backendless/Bin/WP containts files from 21.2.2016.
I wasn’t successful when i tried to rebuild project from source code. Can you send me the latest Backendless.dll for Windows Phone 8.1?

Hi Michal,

Please use the build from the following location: https://github.com/Backendless/.NET-SDK/tree/master/Backendless/Bin/NET_45

Thanks, Michal. Do you happen to have a complete stack trace for the error?

The type initializer for ‘BackendlessAPI.Backendless’ threw an exception.
Method not found: ‘Boolean System.Type.op_Equality(System.Type, System.Type)’.

 PhoneContainer container;
 



 public AppBootstrapper()
