I needed to install IdentityTrainingKitApril2020.VS2010, it made me install WindowsIdentityFoundation-SDK-4.0.
But setup WIF SDK fails with this message :
"Setup has detected that .NET Framework 4.0 is not installed on the system. Please choose the correct WIF SDK(3.5/4.0) installer based on the version of
the .NET Framework you intend to use."
My Machine : Windows 7 Enterprise, VS2010 Professional RTMRel Version :10.0.30319.1 . NET Version:4.0.30319 RTMRel.
I have installed : Windows6.1-KB974405-x86 (WIF Runtime)
