Which versions of .NET are available?

The newest version available today is NET v3.0, but most PC users have v2.0 installed.
Although .NET v3.0 is now available, Windows Update is not automatically installing it, hence few people have it. People who purchase new PCs with Windows Vista pre-installed will receive the latest .NET v3.0 but there may be some versioning issues. Microsoft released a beta version of .NET v3.5 in April 2007.
