Loading a DLL in the GAC

Question

currently I have a problem with getting a DLL into the Windows GAC. I tried to follow the steps of creating a DLL and loading it as described in this blog post: http://blogs.technet.com/b/cloudpfe/archive/2014/02/01/how-to-create-a-custom-authentication-provider-for-active-directory-federation-services-3-0-part-2.aspx

At the point where I try calling the following command:

[System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7514a164b89fa979")

I get an error which tells me that System.EnterpriseServices could not be found:

Exception calling "Load" with "1" argument(s): "Could not load file or assembly 'System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7514a164b89fa979' or one of its dependencies. The system cannot find the file specified."

The specified DLL (System.EnterpriseServices) does exist* on the machine.

So now my question is, why can't this method find the DLL and what do I have to do/change to get this command to work?

NOTE: I Tried this on a vanilla Windows Server 2012 R2 with just ADFS parts installed; And I've called the command from the Powershell.

*UPDATE: The System.EnterpriseServices DLL resides in
C:\Windows\Microsoft.NET\assembly\GAC_64\System.EnterpriseServices\v4.0_4.0.0.0__b03f5f7f11d50a3a
and
C:\Windows\WinSxS\amd64_system.enterpriseservices_b03f5f7f11d50a3a_4.0.9600.1638‌​4_none_53a3f9b13fac0ba5\
So it should be available from the GAC.

Answer 1

I think your public Key token is incorrect, you found your own answer with your update :) .

It should be [System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")

Give this a try.
