How can I adjust the version number for multiple projects without changing every AssemblyInfo.cs file constantly?

The version information needs to be set with the ‘AssemblyVersion’ attribute for each project. However, this attribute does not need to be specified in the project’s AssemblyInfo file. You can create a separate file with the ‘AssemblyVersion’ attribute that is shared across projects that you wish to keep in sync. This file can either be shared via VSS, or by including the file as a link in the projects.
