  • What's the desktop app? Can you link it with the site via a `tel:` style hyperlink? Would it respond to that, if mapped by the user's machine. Some software e.g. Skype will do that – ADyson Jan 12 '18 at 13:14

Your web app can add a value in the registry. On your windows app you set a function in a timer that checks for that value and triggers the desired action.

My bad about the registry as web app will not have access to it. Use cookies instead.

You could use SignalR for this.

SignalR give you

the ability to have your server-side code push content to the connected clients as it happens

The same way someone create a chat desktop app, you could create a app that wait for a message in a site, then trigger an execution of your executable program.
