FlexWiki is a wiki written for ASP.Net The first version had significant contributions by David Ornstein. The first version was used by Microsoft Channel 9 as a means of obtaining community input. FlexWiki was designed to run in a file system or using Microsoft SQL Server.

The second, current, version was mainly developed by Craig Andera. The second version retained all the features of the first version, but added a security mechanism that allows a finer grain of control than was possible in the first version. (See FlexWikiAuthentication, FlexWikiAuthorization and FlexWikiSecurity)

See FlexWikiFeatures for details of the capabilities of the

system.
