asp.net - Can't debug web applications in visual studio 2013 -

i created sample web application in visual studio 2013 , put break point, when running solution break point disabled. set "debug=true" in web.config issues web applications, can able debug console application.

edit:

after clearing both windows , user temp file break point hit, can't able evaluate expression in quick watch. says variable out of scope

make sure have debug set in toolbar drop down on top. right-click home page in solution explorer , set starting page, , try again.

set break point on code in page load event handler of starting page.
