I'm a newbie to C# and .Net, but have been a part-time programmer in Delphi
for some years.

My challenge isn't so much learning the C# language, as the seemingly vast
.Net class libraries (which are apparently split into the Base Class
Libraries and the Framework Class Libraries).

It seems that there is a mountain of superb functionality in these
libraries, but there is just too much for me to take in as a newcomer.  From
where I'm standing I can't really tell what is on offer, and where it can be
found.  I could do with some sort of a "map".

Is there some sort of overview document available anywhere?  Or perhaps a
recommended process for exploring the various areas?  I'm pretty sure there
must be loads of people in my position, who need a structured "way in" to
this enormous forest of code.  I think there's a real risk of me writing all
sorts of code unnecessarily, simply because I didn't realise it existed, or
where to find it, in the libraries.

Any suggestions or pointers would be much appreciated.

Thanks,

SteveT
