Even though it is possible, I do not recommend developing a native application for Windows with Web Views only - this leads to a bad user experience.
Instead, if you want to let users use the application on your computer without internet access, I advise you to install the website on the user's local computer, and the user can access the site through localhost.
Instead of hosting the site in IIS, try using Nancy
for self-hosting . So the end user does not need to have IIS installed.
As an example, I recently used Plex (to stream media). Plex installs a small server on your computer, and then you can manage the app through http://localhost:32400/web
.
