Entity Framework 6.1.3 Could not load - entity-framework-6

Question

So I have seen a bunch of answers to this question. None seem to resolve my issue. I am running the project as a self hosted webservice using servicestack.
Yes I have uninstalled and reinstalled entity framework, cleaned solution, restarted visual studio, rebuilt
Yes I have checked all binding redirects.
Yes I have checked that EntityFramework Dll is in the folder being searched for the dll.
Yes I have permissions to this folder (out of desperation I put the project on my own desktop to eliminate security issues).
Yes the nuget package, the project and all configs have .net 4.5.1 as their target platforms.
Despite all of this, I still get the error:
Could not load file or assembly 'EntityFramework' or one of its dependencies. Access is denied.":"EntityFramework"
=== Pre-bind state information ===
LOG: DisplayName = EntityFramework
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: EntityFramework | Domain ID: 1
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.

Can anyone point me at some tools to track down the cause of the problem (unless you know what the problem is ;-D).

Answer 1

Turns out the "Access is Denied" was not lying. The context I was working with was a wrapper around (inherited from) an actual EntityFramework context which implemented some impersonation in the constructor. The impersonated user did not have access to the bin directory which is the reason for the error.
