System.IO.FileNotFoundException in Backendless.DLL

General
1

I try to use Backendless for a windows phone 8.1 app but it does not work i don’t know why
I created a folder ‘lib’ in the solution and put Backendless.dll in it but always give this message
“Exception thrown: ‘System.IO.FileNotFoundException’ in Backendless.DLL
Could not load file or assembly ‘Microsoft.Phone, Version=8.0.0.0, Culture=neutral, PublicKeyToken=24eec0d8c86cda1e’ or one of its dependencies. The system cannot find the file specified.”



     try {
                    Backendless.URL = "[url=http://l.facebook.com/l.php?u=http%3A%2F%2Fapi.backendless.com&h=UAQFvKKlw]http://api.backendless.com[/url]";
                    Backendless.InitApp("My app id", "my secret key", "v1");
                }
                catch (Exception e) {
                    Debug.WriteLine(e.Message);
                }

Try to get the latest backendless assembly from here:

https://github.com/Backendless/.NET-SDK/tree/master/Backendless/Bin/WP/Debug

Also, make sure that your project uses the 8.1 Windows Phone dependencies:

Are you using the assembly from the github repo or from our website?

6

Try one from github

No, it does not. It is not a “universal” assembly.

We do not have a universal assembly.

13

Is there a way to get this to work with Universal apps?

14

In order for the assembly to work with Universal apps, it would need to be compiled as a universal assembly first. In the current implementation it would not compile that way due to the .NET APIs it uses. It would be totally possible to refactor/change the code to make it universal. If you’d like to help out with that effort, we’d be eternally grateful…

I have just looked at the source code, even though I would love to help I would not know where to start unfortunately. After conversion to a UWP class library project I had about 95 errors, many aiming for things that I couldn’t resolve.
