Full Changelog: AzureAD/microsoft-identity-abstractions-for-dotnet@12.1.0...12.3.0

12.1.0

Added UseBoundCredential property to CredentialDescription to opt in to Bearer-over-mTLS authentication on a per-credential basis. Defaults to false, so existing configurations are unaffected. Consumer libraries (Microsoft.Identity.Web) read this property at credential-load time to either present a certificate over mTLS for Certificate-type credentials, or wire a bound-credential bundle (signed assertion + binding certificate) for SignedAssertionFromManagedIdentity-type credentials. See PR #​252(AzureAD/microsoft-identity-abstractions-for-dotnet#252).

12.0.0

What's Changed

• Revert breaking changes introduced in Abstractions 11.0.0. On .NET 10 target, CachedValue and Certificate extension methods in CredentialDescription were reverted to normal properties. See #​250.

11.2.0

What's Changed

• Properties for mTLS authentication by @​tlupes in Properties for mTLS authentication AzureAD/microsoft-identity-abstractions-for-dotnet#244

Full Changelog: AzureAD/microsoft-identity-abstractions-for-dotnet@11.1.0...11.2.0

11.1.0

New features

• Added StoreWithSubjectName credential source. See PR #​245.

11.0.0

Breaking changes

If you build code with the .NET 10 target framework and get this error:

error CS9260: Feature 'extensions' is not available in C# 13.0. Please use language version 14.0 or greater.

make sure you update the LangVersion property in your project to 14 or later.

AOT/NativeAOT Compatibility for .NET 10+

Made CredentialDescription AOT-compatible for .NET 10+ by using C# 14 extension properties. This is a binary breaking change (though source compatible) for .NET 10+ targets:

• Removes Certificate and CachedValue as public properties from CredentialDescription when targeting .NET 10+
• Adds extension properties with the same names and signatures for .NET 10+, providing property-style access
• Maintains full source compatibility - no code changes required for consumers provided the .NET 10 code is built with C#​14 or later.
• Prevents AOT/NativeAOT configuration binding issues with reference-typed properties
• Keeps existing behavior for older target frameworks (netstandard2.0, netstandard2.1, net462, net8.0, net9.0)

Technical details:

• For .NET 10+: Certificate and CachedValue are implemented as extension properties (not visible to config binders)
• For older TFMs: Certificate and CachedValue remain as regular public properties
• LangVersion updated to 14 to enable C# 14 extension property syntax
• Internal accessor methods (GetCertificateInternal, SetCertificateInternal, etc.) support extension properties

This enhancement ensures CredentialDescription works seamlessly in AOT/NativeAOT compilation scenarios while maintaining backward compatibility.

New features

• Make CredentialDescription AOT-compatible via C# 14 extension properties (v11.0.0). See PR #​238.

Bug fixes

• Invalidate _cachedId in all property setters that affect Id computation. See PR #​240.

Fundamentals

• Add codebase navigation guides and architecture decision records. See PR #​241.
