We have a very large, very slow, distributed network.
On the network we have a Main central server, as well as a smaller server at each individual site.
Since we have slow lines, and our application is quite large (20MB) we cannot have all our client PC's (300+) installing/updating the application from the Main central server, so I create separate ClickOnce Deployments for each site respectively.
This allows the majority of our users to install/update the application over a fast LAN connection from their local server.
However, the more sites we add the more cumbersome this gets since I have to publish a separate copy of the application for each and every site, each time making sure that I don't mess up the URL's etc. (This happens quite easily)
Is there a way to change the Installation URL & the Update Location URL after publishing the application (preferably programmatically)?
If this is possible, I will create a distribution system that uses a single ClickOnce deployment, modifies it for each server, and copies it to the correct location on each server.
If this is not possible, I will have to continue publishing separate deployments per site and this will most probably force us in the longer run to re-invent the wheel altogether and stop using ClickOnce.
