I am trying to explaing that they are not to save you. CAS is to save you.
"No Touch" is the ability of the runtime to execute somthing just by giving
an URL. It simply eliminates the need to download all the files manually and
makes administrators able to maintain a central instance of the application
on a single URL. Treats that URL as a base to find configuration, dependent
assemblies, ... And of course CAS has code origin security as well based on
that URL. So it can make "No Touch" more safe but "No Touch" is not based on

"No Touch" is a feature of .NET Framework since version 1.0.

"Click Once" is designed to deploy the application much like an installer.
It is not designed to elevate security. It has the ability install the
application with full trust if needed (with your confirmation) but it is
only a minor feature not "Click Once" itself.

For a short explanation along with a picture see:

Note that the publishing wizard is in Visual Studio and the installer is on
the web server.
