I had the same issues which I have since fixed in VS 2015, my situation was:
- Update from Windows 7 --> Windows 10
- Installed VS 2015
- Enabled IIS so I could then open the management console & do lovely things
- I then tried to host a .net 4.5 Web API in my local IIS mentioned above
Result was 404 errors.
To fix:
- Open the Developer Command Prompt for VS2015 as Administrator
- Run
dism /online /enable-feature /all /featurename:IIS-ASPNET45
- The operation completed successfully
