Why don't the express editions support "Tool" extensions..? As far as I can tell, the majority of extensions available fall into this category.
If there is some legal reason behind this, then it needs to be made more obvious. Being an extension developer, I'm a little worried about this - my extension simply refuses to run on the Express edition. The build output gives me a slightly cryptic warning
message about targeting express editions, which I pasted into google search and got 0 results.
There's a couple of other forum posts out there about this, but none of the answers from MS people seem to give a reason why... Except one from 2007 which mentions a EULA (who reads those things anyway? heh)
