title: How do I update a deployed clickonce application without having to redownload every file?
body: <p>I have an application with a database that I am running.  I added all the dll's, exe's and db files I needed.  These are content that are not going to be compiled.  So I have set their Build Action as "Content" and their Copy to Output Directory as "Copy if newer". With this, everytime I publish a newer version of the application, I change only one file slightly, yet still all the files are redownloaded.  I have looked around here and apparently there is a hash associated with all the files.  But they don't seem to be giving me an answer of how I can publish a new version of an application, and have the end user only download the files that have changed?</p>
