Convert API consumer into various languages

Hey! Are you good at languages?

I need to convert the attached C# solution into:

Python
Java
C/C++
PHP
Swift
Objective-C

Please keep the result as close as possible to the original in style, organisation and usage of dependencies.

You can demo using a test harness prior to supplying the final code and binaries.

I think the task is straightforward since there are many tools for automatically translating between languages.

Thanks!
