Azure Active Directory IdentityModel Extensions for .NET

Nuget

IdentityModel Extensions for .NET provide assemblies that are interesting for web developers that wish to use federated identity providers for establishing the caller's identity.

Versions

You can find the release notes for each version here. Older versions can be found here.

Note about 6.x

If you noticed, we bumped the release from 5.x to 6.x
We were maintaining two releases from two different branches.
dev - 6.x
dev5x - 5.x

Internally at Microsoft we were quickly required to remove all 3rd party libraries as IdentityModel is all about securing resources.
Since there were some breaking changes, given the time-line we had to maintain two releases.

Both of these branches were public and moved forward mostly in lock-step.
Once we finished our SignedHttpRequest functionality in the 6.x branch, we realized the delta between 5.x aqnd 6.x was too large to maintain in both branches.
We decided now was the time to switch to a single release branch.
Since internally the versioning was at 6.4.2, we needed to release at 6.5.0.

There are some small breaking changes

We built and tested ASP.NET core with 6.5.0 without issues.
We also upgraded in place existing applications to 6.5.0 without issues.
This of course does not mean you will not hit issues, but we took it seriously.

Any questions or compatibility problems please open issues here.

Thank you for using our product

The IdentityModel Team.
