Just a quick one... The PDC build of Whidbey has XML Documentation comments in VB that look something like:

'@ <summary>
'@ A method.
'@ </summary>

The “@” was used as a placeholder while we did some testing and discussion about what the marker for the comments should be. An obvious choice would be ''' (three comment ticks in a row), but we had some concerns that the comment/uncomment block IDE feature might negatively interact with it (i.e. you do “comment block” multiple times on a section of code and all of a sudden you're getting weird XML Documentation warnings).

However, we've decided that we do like ''' the best, so we're going to slightly modify comment/uncomment block to add a space after the comment tick to ensure it won't create XML Documentation by accident. So in the beta, XML Documentation comments will look like:

''' <summary>
''' A method.
''' </summary>

More feedback is always accepted. (Though, please, no accusations that we're changing the syntax because we think VB developers are too dumb to understand “@”... <G>)
