The long parameter names of the Pack command options have been changed to start with --.
The output folder for the package of the Pack command was a relative path from the project folder in V1.1.0, but from V1.2.0 it has been changed to a relative path from the folder when the NDExt command is executed. If you want to execute it in the project folder as before, change the directory when the command is executed and then call the pack command.
In response to the change in Next Design V2.0 Service Update1, the pack command has been modified so that it does not use the title tag of the nuspec file.
