The closing session of UK Mix07 was a “Sneak peeks” in which we were shown a variety of snippets of varying degrees of interest. One was a brief glimpse of Expression Web 2.0, Microsoft’s web design tool, showing “PHP script” on the File – New menu.
The extent of this support was not discussed. The minimum would be some level of syntax highlighting, which would be trivial to implement, so this may not amount to much. Still, it is interesting as a sign of the times. When I spoke to some folk from Zend a couple of months ago, they emphasised their IIS support and good relationship with Microsoft, so it looks as if both sides want to play nicely together.
