I have installed the Windows Identity Foundation but can\'t find the Microsoft.IdentityModel dll. According to the Azure Hands-on-Labs it should just be in Add Reference in
For Windows 10:
Right-click the taskbar Windows logo, select 'Programs and Features'.
Click 'Turn Windows Features on or off'
In the dialog box that appears, scroll down or resize the window and check the box next to 'Windows Identity Foundation 3.5'
Click OK.
This activates the required DLLs. Apparently Windows 10 keeps all of those features in the windows installation so that it can activate and deactivate them on demand.
