So after formatting my pc I reinstalled Visual studio 2015 and loaded all my projects,all of them runs fine instead of one that was created in VS 2013 , when trying to run the project it builds successfully but will not run instead I get the error
invalid pointer
and that is all after some digging I looked at the activity log and I see this error :

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

didn't find many places talking about this but from what I found I tried these suggestions:
1) renamed the profile directory
C:\Users\blabla\AppData\Roaming\Microsoft\VisualStudio\14.0
2) deleted the registry key associated with the error GUID
but nothing is working any help would be appreciated.
PS: the project I'm trying to load is Windows 8.1 App built with c# with Xaml
