I created an asp.net MVc 3 application using Visual studio 2010. It was working fine. I uploaded to hosting which has asp.net MVc 3 installed and it worked. I opened this MVC 3 solution in visual studio 2012. At that time, It did some up gradation. It created
151Marketing.v11.suo
UpgradeLog.html
UpgradeLog.xml
and a folder named _UpgradeReport_Files and backup folder.
When I publish this on live server, I get errors of framework. I see a backup folder as wel as I guess it was created before conversion by VS 12. Should I use that or is there any other way to change the current version of code to work on hosting because after i opened it in VS 12, I made several changes as well.
Please suggest
