App Pool Name Cannot Be Specified with a Variable?
This is probably just a case of a user who doesn't know what he's doing...
For some reason, when using the Web.Iis7AppPool activity, I can use a variable to specify the MachineName, for instance; but I cannot do so for Name (cf. attached image; note that the ellipsis doesn't appear).
I tried to edit the xaml and put brackets around the variable name (e.g. [AppPoolName]), but it generates an error ("Invalid application pool name") when the build is run.
I also tried looking at the source (Iis7AppPool.cs and BaseRemoteCodeActivity.cs), to see why this would be so, but nothing is jumping out at me; I don't even have a plausible hypothesis.
