A description from Microsoft:
LitwareHR is a fictitious HR application providing recruitment management software delivered as a service. The most important aspect of this application is not what the application does, but how it does it. Using the latest Microsoft technologies such as .NET Framework 3.0 and SQL Server 2005, LitwareHR implements single-instance multi-tenancy patterns. These patterns, previously described in our whitepapers, are available in the MSDN SaaS Architecture Center.
There are source code, documentation, and webcast.
