Does anyone know how to convert GSM audio into PCM WAV via C#? I have tried to find a viable solution on the Internet to no avail.
Here is a link to a C library that encodes and decodes GSM files:

and a link to more information on the subject:

It should be possible to either compile the C code as a DLL and call it from a C# application using PInvoke, or else incorporate the methods directly into your C# app.
Once you have the GSM data decoded into sample data, writing it out to a WAV file is very simple.
