Installing Conchango Scrum for Team System
The Conchango Scrum for Team System process template is installed on the TFS application server. A prerequisite is Team Explorer 2008. Ever wonder why a UI component must be installed on the application server?
The processes used within the Scrum for TS template (and it's associtated web services) require access to the Team Foundation APIs that are installed as part of the Team Explorer. These APIs cannot be re-distributed along with the process template installer as several are compiled into native images during the installation process.
