Since your requirements does not fit the ClickOnce and your application is WPF, I would go with creating a Updater class that would download an assembly (DLL) from your server to a specific folder, and have an Folder Observer class that would try to load the new arrived assembly using Prism... But that is just an opinion...

Your Updater class would request to a WCF service to see if there is a new assembly to download, once it has the same class can Download the new assembly from your server and save it in a module like folder...

Since you would have a class that is always looking into the module like folder for new assemblies it will be no problem to load the new assembly into the ModuleCatalog of the CAL (Composite Application Library). Once the assembly is loaded you will have the new content into your application.

This can also be achieved using MEF (Managed Extensibility Framework).

I would strongly recommend that you study both MEF and CAL, and try to figure what suits you better (maybe both).

Hope this helps.
Best regards

Updating every three days may be tough schedule to meet. Limiting the size of the update may also be a problem, it's going to be a large as necessary to update the required functionality.

ClickOnce can be configured to check for updated before the app starts. Otherwise you'll need to devise a plan to use shadow folders.

Does ClickOnce appropriate for an application that might be install on for example 400 clients?

There is no limit. Of course, depending on your network and size of the application, if all users are downloading at the same time it could present a performance issue.
