C#-Wrapper for a C library (LibOFA)

Hi, we need a developer who knows C and C# to create a wrapper class for a C library. This includes the conversion of all dependencies that the method might have. You need to wrap a method that creates a fingerprint for a music file. To achieve this you can use the LibOFA Library (written in C). You can find the source code at: [login to view URL] The resulting method should be usable like this: public static String createFingerprint(String filename); It gets a path to a mp3 music file and produces and returns the fingerprint from libofa. Before you bid: Please have a look at the libofa library and check if you can really do the job and if there are any dependencies that might give problems. Please only bid if you know that you can do the conversion. Some requirements: -Pure C# interfaces needed (but you can use external C/C++ DLLs if needed) -Needs to be working without any pre-requirements on Windows XP, Vista and 7 with 32 and 64 bit Best greetings, Sven
