See README.building in the MCS directory.

The single biggest source of confusion seems to be the "Your runtime is
out of sync" messages.  Realize that this is *normal* while BUILDING. 
Think about it: you're building a new class library with the old
runtime.  If the new class library references a function that the old
runtime knows nothing about, the runtime system issues this warning.

I'm sure there's a better explanation for it, but that's the general

Solution: compile <cvs module="mcs"/>/class/corlib FIRST, build mono,
install mono & the new corlib.dll (in <cvs
module="mcs"/>/class/lib/corlib.dll), and then build & install the rest
of the mono class libraries.

Repeat as needed whenever the runtime changes.

Note that you may need to build & install the mcs compiler before
attempting to build the class libraries.

Just don't panic when you see the "out of sync" messages.  They're not
indicative of something being horribly wrong, UNLESS you get the message
after installation when running programs.  THEN you should worry.  (And
rebuild & re-install all of mcs to fix it.)

I'm a vim user myself, which has C# syntax highlighting but not code
completion.  I know others use vim as well, but I'm sure some use
Emacs.  I've heard that Visual SlickEdit is also a good editor.

On windows, SharpDevelop is popular:


SharpDevelop is also being ported to Linux.  I'm not sure when it will
be available, though.

I'm not sure what needs to be done to set up a mono-using environment.

Be Specific.  Well, System.Diagnostics (<cvs
module="mcs"/>/class/System/System.Diagnostics) could use some loving. 
In particular, the EventLog and related classes (CounterCreationData,
InstanceData, PerformanceCounter, etc.) have been stubbed (the stubs are
commented out), but many of the classes need an implementation.

I started these, but they look to be largely Win32 specific (though
EventLog could probably be mapped to the syslog(3) Unix function), and
other things caught my interest.

Isolated Storage (class/corlib/System.IO.IsolatedStorage) could use some
loving as well, as it currently only has a rudimentary implementation.

Everything could probably use more test cases.

AFAIK, there are some bugs that the test cases have found.  Those need
to be fixed.

Bugzilla also has over 100 bugs that should be looked at and fixed when
possible.  See the following link (beware line wrapping):


System.Xml also needs help, as does parts of remoting, and other areas.

You should also take a look at mono-devel-list:


In short, you could probably pick any area of the class library and put
some work into it.  So go where your interests lie.

Some of these questions are FAQs, but they're not in a FAQ yet. :-)

Plus, some of the answers are temporal in nature (the parts of the class
library that need attention will change over time).  So it might not be
sensible to have a FAQ entry for them.
