I was looking for a some kind of ASP.Net sample site purely to demo some BDD scenarios at work, but then I wanted to do it on a site which is more complex than the usual ASP.Net sample site made of Customer/Order.
I found a couple of Wikis, but the one that caught my eye was ScrewTurn Wiki. First things first it is free under the GPLv2 license (for more details on commercial licenses see Commercial License Help)
The installation took less than a few minutes using the Microsoft Web Platform installer, You install the Wiki in one of two modes file system storage mode or SqlServer storage mode (just use SqlExpress). To choose which mode you want to install. See Installation Help for more details. Apparently you can go with file storage mode and then switch to the SqlServer data storage mode later (Data Migration)
The fact that you can manage the ScrewTurn Wiki using Microsoft WebMatrix is simply brilliant. The ease of use and ability to be able to publish the Wiki is simply useful. You can pretty much configure your hosting details if you wanted to host something on the internet and keep pushing your changes.
Now for Plugins, quite a lot of them seem to be available. There are vast number of navigational, text editing and data provider plugins. In addition to this you can customise different portions of the Wiki using your own providers , this seems like one of those things that was given a great deal of thought. See Custom Providers
I guess I am very impressed by what the Wiki offers, but looking at the features I am actually wondering if a product which was a Wiki is evolving into a CMS? Not sure, cant say I am bothered either, the only reason I raised that concern is the Wiki as is, is pretty simplistic and this is what appealed to me, building too much into could make it bulky and complex. I am just a developer so I cant give an accurate view of what users of the Wiki would want. On the bright side there are some really new features that are coming and that can be leveraged. V4 CTP offers native Azure support which should be good if you wanted to use Cloud based services I guess. See Roadmap for more details
