C# interface for the SPI peripheral X86J4105

Is there a .net library for the SPI interface in Win10
Or do i need to use Linux to directly access SPI.

Is the bandwidth available over SPI similar to Raspbi Pi.

Recommend to use Linux to access SPI

Is there a mono library for Linux to access SPI or C or do i have to use Python ( yuck! )

Python also calls C.As long as you can see the /dev/spidev device, you can read and write through C in Linux.
