does microsoft take part in making .Net for linux or is it just implemented
by others?
and how much compatibiliy should i expect?
in other words how much change should i expect to get the the code written
in windows .Net to run on Linux .Net??

Try at http://www.mono-project.com/

It really depends what you are dealing with .. many things would not be
architecturally sound moving to linux.

Anything in the spec should be good .. beyond that some areas are evry good
some are not supported at all. You really need to check to see if what you
are doing has been supported or not. As an example using a heavily COM based
architecture would not make alot of sense. Other things will simply not work
because they make no sense (pinvoking windows apis as an example)

There is a great book "Cross Platform .NET Development" which is a bit dated
(so most likely inexpensive on amazon new & used) but most of the info it
covers still holds true.

I wouldn't bet on .NET with platforms other than Windows. When .NET first
came out, it was siad then that it was designed to be port to multiple
platforms, just like Java, if there were other partis interested in doing
so. after 6 years, Mono is the only one ( i have no idea how good it is to
use in a production evironment). Just look the MS's move to .NET3.0, it is
obvious that .NET is getting tied even more tighter to Windows platform.
