The purpose of this enhancement is to store SDD's along with an index of where to find the SDD within our registry.


  • This code must store the SDD on the machine
  • This code must update the registry with information on where to find the SDD for the product.

Design details

The Registry schema has been updated to include uri's that will point to both the sdd and the spd.

The sddContext will be changed to include member variables that contain this information.

Once registry update is called we will update the registry, copying files to a folder within the folder registry.xml is at called "registry_files" and noting their name within the registry.

Impacts of this enhancement

  • The SDD runtime will be able to dynamically locate and load SDD's to help in both future updates and uninstalls.
