Lets say I deploy my apps using clickonce, online only option.

Suppose all of the apps I deploy using clickonce go to the same location, which is simply a folder in a fileserver.
Now every one of my applications has a .application file in this folder that I cancreate a shortcut to.
After executing this .application file, all of the files needed for
the correct version of the app are copied to the ClickOnce cache, then
the program is run.

Now... lets say I have 50 different apps, all deployed using clickonce.
And lets say that ALL 50 reference the same DLL, and the DLL changes.
From what I understand, I would have to open every single project in vs, rebuild, and republish.

If I wanted to be able to put this common DLL in one spot so that when the DLL changes, I can simply drop it somewhere, and the .application
file will know to grab the updated DLL to copy to the clickonce cache
next time a user decides to run the program, how would I go about
setting it up?

Thanks in advance.

Have that dll installed to GAC and service it seperatly. That is the most appropriate way. ClickOnce can not service individual components like CLR does using publisher policy
