Online CLI Resources
Rotor’s homepage can be found at http://msdn.microsoft.com/net/sscli. Rotor’s online community (newly minted at the time this was written) can be found at http://www.sscli.net.
The official web home of ECMA and its standards specifications is http://www.ecma.ch, although the specifications for ECMA-334 and ECMA-335 are also widely mirrored.
OnDotNet (http://www.ondotnet.com) and its umbrella site, the O’Reilly Network (http://www.oreillynet.com) often have CLI and Rotor-related articles and weblog entries.
The University of Pisa hosts a .NET web site (http://dotnet.di.unipi.it) and Rotor-related mailing lists, as well as indexed source code and other resources. DevelopMentor hosts several CLI-related mailing lists, which are archived at http://discuss.develop.com. There is an active newsgroup at http://nntp://microsoft.public.shared_source.cli.
There are two significant open source projects built around the CLI specification: the Mono project (http://www.go-mono.org) and the DotGNU Portable .NET project (http://www.southern-storm.com.au/portable_net.html). Look to these sites for yet more interesting source code.
