I have a website which contains multiple pages, crystal reports and etc.. I look at the web config of the web site and I see its framework is 2.0.
I need to upgrade the web site's framework to 3.5. When I go to web site's Property Pages >> Build I thought I could change it but visual studio didn't give me that option. Am I missing something? Is this achiavable? If so how can I do it? Thanks in advance.
