After upgrading to Windows 10, I started getting this error:
ASP.NET 4.5 has not been registered on the Web server. You need to
manually configure your Web server for ASP.NET 4.5 in order for your
site to run correctly.
I searched on it and found this link ASP.NET 4.5 has not been registered on the Web server
I tried the accepted answer.
Unfortunately, on Windows 10, this doesn't work. It'll respond with:
Microsoft (R) ASP.NET RegIIS version 4.0.30319.0 Administration
utility to install and uninstall ASP.NET on the local machine.
Copyright (C) Microsoft Corporation. All rights reserved. Start
installing ASP.NET (4.0.30319.0). This option is not supported on this
version of the operating system. Administrators should instead
install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Windows
Features On/Off" dialog, the Server Manager management tool, or the
dism.exe command line tool. For more details please see
http://go.microsoft.com/fwlink/?LinkID=216771. Finished installing
ASP.NET (4.0.30319.0).
After this I opened Programs and Features window, hit the "Turn Windows Features on or off" in the left pane.
I click on
Internet Information Services -> World Wide Web Services ->
Application Development Features
But I can't see there ASP.NET 4.5 option.
How can I solve this issue?
