SharePoint Tip of the Day – Where is the Microsoft.SharePoint.IdentityModel.dll in #SP2013 ?

SPFederationAuthenticationModule and / or using Microsoft.SharePoint.IdentityModel anyone ?

Wondering why you can’t add reference from Visual Studio to this DLL ?

Turns out that you need to make a reference to the dll from the gac (or copy it from it)

Assuming windows is installed on your C drive (you’ll be clever enough to figure out the other path otherwise) :

C:WindowsMicrosoft.NETassemblyGAC_MSILMicrosoft.SharePoint.IdentityModelv4.0_15.0.0.0__71e9bce111e9429cMicrosoft.SharePoint.IdentityModel.dll

Thanks ILSpy & GacView utilities (would marry both them if they were not utilities !)
