Connect to CEN/XFS device from C#

Question

I'm trying to connect my C# application to Encrypted PIN Pad through CEN/XFS.

I installed and read protocol documentation from CEN website. During my research I read that I should use msxfs.dll to connect to XFS Manager which is build in C language (at least that what I read), and there is no documentaion regarding this dll as Microsoft don't own it, and it follow CEN standards.

I'm lost and looking for some guidance regarding my starting point:

• Should I copy msxfs.dll beside my application and start calling msxfs.dll functions depending on CEN specicifations.
• Or I'm moving in the wrong path, and there is another way to build integration?

If anyone has any article or tutorial regarding how to connect to CEN/XFS using C# that will be very helpful, all the samples I found was through using j/xfs or they were describing how to build SPI functions not how to consume API functions.
