I'm facing this error. How could I overcome this error? I am new in Entity Framework. Any help would be very much appreciated..

Assembly 'HRMSDataAccessLayer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' which has a higher version than referenced assembly 'EntityFramework, Version=4.1.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089'

You are referencing an older version of Entity Framework than what is required by HRMSDataAccessLayer. – ryrich
How can I change the version of Entity Framework? In properties file Target .NET Framework is given 4.5 @ryrich – Milon Sarker
EF version 4.4? I can't even find this version on NuGet – Marco
I updated both Entity Framework version and it worked just fine. Thanks everyone – Milon Sarker

Add the reference for the higher version in your solution.

Assembly 'HRMSDataAccessLayer, .. uses 'EntityFramework, Version=4.4.0.0, ...
which has a higher version than referenced assembly 'EntityFramework, Version=4.1.0.0,

You need to add the reference for the Entity framework version 4.4.0.0

Hope that helps.
