I have not had any luck finding a consolidated view of changes from ADFS 2.0 to 2.1. Is there such a resource out there? I'm interested in new features.
Also, I'm looking specifically if AD/LDS can be used as an IdP for ADFS 2.1. I believe this was possible in ADFS 1.0, then not in ADFS 2.0, and I'm hoping (though against hope, I think) that it's back in ADFS 2.1.
Thanks for any help on either of these two questions.
Refer: Guidelines for Migrating an Application Built Using WIF 3.5 to WIF 4.5.
That's the basic difference.
In ADFS 2.1, ADFS and WIF are built-in - no need for seperate downloads.
For completeness, in R2, Extending device support in Active Directory.
No - no change to LDS.
