c# - EntityFramework error: The provider did not return a ProviderManifest instance -

my project using asp.net mvc4, in c# visual studio 2012 web express.

when compiling project, have next error:

the provider did not homecoming providermanifest instance. not determine storage version; valid storage connection or version hint required.

after many hours of search believe error somehow related entity framework. found work around error here: http://forums.devart.com/viewtopic.php?f=32&t=25748

the workaround suggests alter field providermanifesttoken="2012" providermanifesttoken="2008" in .edmx file.

after doing error goes away. have problem when run project, runtime error:

dockis name of project. after seeing error spent several hours believing errors lied somewhere in versions of bundle beingness used. however, not seem case, since bulk of packages date , there doesn't seem conflicts between them.

consequently, believing problem lies version of entityframework, out of ideas on how prepare this.

i'm ears, if have suggestions, i'll appreciate them.

download http://www.microsoft.com/en-us/download/details.aspx?id=40762 , update nuget ef 6.1.3 , everithing work fine.
