Solved! WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for jQuery issue

This is very small post to tell about a issue that popped up in my day's work. Did some bing on the issue and found the below codeproject article

http://www.codeproject.com/Articles/465613/WebForms-UnobtrusiveValidationMode-requires-a

However, none of the solutions mentioned there worked for me. After reviewing my change before I check-in found that as part of my upgrade to MVC 5.2.3 version I have updated the httpruntime node of web.config to include targetframework

<httpRuntime targetFramework="4.5" ... />

Once I removed the highlighted attribute the issue is resolved. Hope this will be useful for someone :)
