How to use API under .NET in windows phone?

Question

API

Hello, I'm interested in programming under windows phone 8. There is an API for .NET for my application, but I can't use it for WP.
In general, is it possible to use the API under .NET in windows phone? If so, how to replace libraries that are not available for WP? For example, in .NET, you need to use the xml file app.config, which contains the token, but WP does not recognize the necessary tags. I ask for help from people who have experienced similar things or have experience using third-party APIs on WP. Forgive me for perhaps a stupid question, because. I'm still very weak at this.

Answer 1

on it, you can use any libraries from which there is a source, provided that you can recompile them under wp. About "WP does not recognize the necessary tags" this is a problem from the category "it broke / deleted / transferred the computer itself", wp does nothing on its own, what the programmer tells him to do, if wp did something wrong, then it was explained to him wrong.
