I just had the same problem. Here is how I fixed it...

Use the run command to run appwiz.xpl

Click on Turn Windows features on or off

Expand World Wide Web Services, Expand Application Development Features, and check the boxes ASP.NET 3.5 and/or ASP>NET 4.6 depending on which version you are targeting.

Click ok

Restart IIS Server.

Hope this helps.
