Could not load file or assembly ‘Microsoft.IdentityModel’

  • Artykuł

I ran into a problem trying to authenticate with CRM 2011 Online, I received the following error message when I tried to run my code:

Could not load file or assembly ‘Microsoft.IdentityModel Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35’ or one of its dependencie. The system cannot fine the find specified.

The reason for receiving this error is because I don’t have the Windows Identify Foundation Pack installed on my Windows 7 machine.  To resolve this problem, I downloaded and installed the Windows Identity Foundation Pack.

    At work we usually try to include EVERYTHING a developer may need right in the solution so he can just check the entire thing out on a brand new machine with a stock Visual Studio and it will work. Do you have any idea which .dll gets installed with Windows Identity Foundation Pack that, when missing, causes that error? I'd love to just include it instead of having developers install the pack.

    I tried downloading Windows Identity Foundation but it was already on my machine.  I get this error after publishing the site, the site works fine on my localhost. I am using VS2012 and the Target Framework for the site is 4.5.  Could this be the problem?

    Thank you for identifying the issue. You can also include the Windows Identity reference in your project when you build and deploy.   As an earlier commenter mentioned.
