Could not load file or assembly entity framework 5 .Access denied

Question

Hi All,
I am using secure store applicatin id(set credentials using my windows account) to get the data from sql server using entity framework and WCF.
When trying to run webservice I am getting below error
System.IO.FileLoadException: Could not load file or assembly 'EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. Access is denied.
here i am trying to impersonate using my account. All works well when I give access to bin folder.
But this is not correct. I can't give access to myself to bin folder or temp .
is there anyway to get rid of this error.
Any help is appreciated.

Answer 1

I think giving access to bin or temp folder is not good. Also, EF dll in Gac is not good approach.
I am wodering why the first time deployed dll is working and if i do iisreset then it's not working
below is the detail error
