Hello Venkata,
This question was previously asked on our forum here - we do not have any current cross-platform support of .NET (Mono or otherwise). We do have support for many other APIs that can be used on Mac / Linux / Unix / etc.
However, if you have a compelling business case for using .NET on non-Windows platforms, our product management team would certainly like to hear about it. You can message Jason Hinsperger with any product support feedback you would like to pass on.
Thanks,
Jeff Albion
