Windows Phone and ANSI C (not C++) library

Question

Is there any way to write / include ANSI C written library to my Windows Phne 8 app project? I know it's possible with Windows Phone Runtime Component for C++ but here is my question, it is possible for ANSI C? The goal is cross-mobile library for Android, iOS and windows Phone

Answer 1

Microsoft has fixed the [DllImport] in WP 8.1. If you target WP 8.1, you can compile your ANSI C library into the DLL and invoke your DLL directly from the C# code, without any C++/CX component.

Update: Please note you must use visual studio to build that DLL. Also, remember the native code is always CPU-specific, which means you'll need separate x86 build for the emulator, and ARM build for testing on hardware devices, and for the store.
