I received the RTM bits for the upcoming Whidbey beta yesterday and installed them last night. This morning I installed the documentation. Save for a glitch that required me to modify the docs’ Setup.ini file, the install went smoothly.
The build process that Microsoft uses to produce Whidbey drops is very complicated. The doc folks and platform folks often get out of sync, with the result that the docs won’t install or won’t run after they install. If the bits that go out to the public require the same Setup.ini modification that my bits required, I’ll post instructions here.
