Open local desktop files

[mkant078]

Hi,
I am new to GitHub, so please do not shoot me if I have a stupid question.
For our intranet I need to open local desktop applications (MS Office Excel) by clicking a link on the intranet webpage. Since all browsers have a level of security that make this impossible, I thought CefSharp could be a good solution to make my own browser without this security. Or at least to turn off this security setting. I think it has something to do with a Local Storage setting, correct me if I am wrong.
Is this possible with CefSharp? If yes, can someone point me in the right direction.
Thanks

That's not exactly correct, every major browser supports the opening of external applications on Windows. See https://nishantrana.me/2020/09/22/use-custom-browser-protocol-to-launch-desktop-applications-from-dynamics-365/

I'd suggest evaluating this option before writing a custom browser.

If you decide to use CefSharp see https://github.com/cefsharp/CefSharp/wiki/General-Usage#protocol-execution for an example that you should be able to adapt.
