httpRuntime targetFramework="4.5" causes 500 - Internal server error

Question

I am converting mvc4 project, 4.0 to 4.5

I need to add the folowing line to system.web in web config, but when I do, I get 500 - Internal server error

 <httpRuntime targetFramework="4.5" />

Did you change the target in your project build settings to 4.5? — Travis J, Jun 14 '13 at 22:35
Must be your code then. Try to get something more concrete than a 500..that is really vague. Get to an inner exception and post it. — Travis J, Jun 14 '13 at 22:47
This is a general message, find the actual reason. Check this answer : http://stackoverflow.com/questions/5385714/deploying-website-500-internal-server-error/5385884#5385884 — Aristos, Jun 14 '13 at 23:10
@user1615362 Is your pool 4.5 ? meaning, that you must also have update your net from 4.0 to 4.5, not only the project. — Aristos, Jun 14 '13 at 23:36

Turns out that I was trying to add the httpRuntime, when it already existed at the end of the system.web. To resolve the issue I did a merge:

<httpRuntime maxRequestLength="102400" executionTimeout="1200" targetFramework="4.5"/>
