Because Extensions use the Delta file format, we must run the command that creates Delta files. Delta files are outside of the scope of this book, but information can be found in MSDN at: https://msdn.microsoft.com/en-us/library/dn762344(v=nav.90).aspx

To create Delta files we must export all the objects from our Dynamics NAV database and compare them to a similar export from a clean Microsoft database.

The following script is used to create the Delta files:

Compare-NAVApplicationObject    -OriginalPath "Q:WDTUOrriginal.txt" ` 
                                -ModifiedPath "Q:WDTUExample.txt" ` 
                                -DeltaPath "Q:WDTUDelta" -Force

In the preceding script, Q:WDTU represents a location in your filesystem where the extension will be created.

The result of running this script is a set of files in the Q:WDTUDelta folder with the .DELTA file extension.
