IdentityModel 8x

Reminder

All the IdentityModel libraries must have the same version 8.0.0 in your project and including the recursive dependencies.

dotnet restore yourProject.csproj
dotnet list yourProject.csproj package  --include-transitive

to see the list of all packages dependencies.

Introducing IdentityModel 8.x

We are excited to announce the release of IdentityModel 8.0.0, a major update to our popular .NET auth validation library.

Migrating to IdentityModel 8.x (work in progress)

Breaking changes

Dropping of NET 4.6.1 support

IdentityModel 8x no longer supports .net461, which has reached end of life and is no longer supported. See issue #2544 for details. The table below contains changes encountered when upgrading to newer .NET versions from 4.6.1.

File	What Changes	Versions change occurs in
src/Microsoft.IdentityModel.Tokens/ECDsaAdapter.cs	Using ECParams vs CNGKey to generate ECDsaFunction… This happens as an internal abstraction when creating an ECDsaSecurityKey	NET 4.7.2 NET 6.0+
src/Microsoft.IdentityModel.Tokens/Utility.cs	When evaluating IsHttps(Uri uri) uses Uri.UriSchemeHttps to compare for equality rather than just the string “https”	NET 4.7.2 NET Standard 2.0 NET 6.0+

No longer supporting two Identity Model .dlls

IdentityModel extension dlls Microsoft.IdentityModel.KeyVaultExtensions and Microsoft.IdentityModel.ManagedKeyVaultSecurityKey were using ADAL, which is no longer supported. The affected packages have been removed, as the replacement is to use Microsoft.Identity.Web. See issue https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/issues/2454 for details.

Removed Identity Model 7.x App Context Switches

AppContext.SetSwitch which were included in IdentityModel 7.x, have been removed and are the default in IdentityModel 8x. The result is a more performant IdentityModel by default. See App Context Switches in Identity Model and PR #2644.
