    abhishekgupta hi there.

    Since binding to VRF is Linux-specific stuff, I would suggest to call library functions using p/invoke

    you will need to call 

    setsockopt(sd, SOL_SOCKET, SO_BINDTODEVICE, dev, strlen(dev)+1);

    but in c# using https://iq.direct/blog/424-how-to-call-p-invoke-in-c-on-linux.html
