I just wrote a wiki in C# / Asp.Net for small teams, running on intranets with active directory and a sql server. You can grab it from github: http://github.com/chrishulbert/SimpleCSharpWiki Features: * Designed for small enterprise-environment asp.net development teams * Clean interface, the idea being that overworked programmers are more likely to document things if its quick * Very simple to use and deploy, unlike most wikis * Integrates well in an enterprise environment, eg with IIS, Sql Server, and Active Directory * Single sign-on, so you don't need to remember another frigging login/password * Shows a tree view on the left pane of all wiki documents
