I'm develop provided-hosted app (MVC) in SharePoint Online. I've installed Visual Studio Community 2017. Unfortunately, when I try to debug and install Add-In, Visual Studio freeze and not responding. If I set web application(MVC) project as only one startup project, everything works. When I try to debug only add-in application I have freeze. Even If I try to debug both projects (web app and Add-in app), I have the same freeze. The same problem occur with fresh Add-in instance. Build log looks like below:
3> Install SharePoint Add-in:
3> Uploading the SharePoint Add-in...
3> Web.config updated with Client ID 141eecda-c722-4293-9696-5efd5bb01184

(Freeze and not responding)
I've installed Mozilla Firefox and I figured out that issue occurs when project is debugged on Chrome. I'll try to reinstall chrome and I'll see what will happen.
