[Azure SDK] Outdated version of Azure.Core and Azure.Identity for Microsoft.Identity.Web.Certificate can cause TypeLoadException / BuildError / ....

[tebeco]

Hello,

Reason for all that before anyone read:

A lot of library already updated to modern version of Azure.Core + Azure.Identity and can't just be downgraded
example:

• https://www.nuget.org/packages/Azure.Messaging.ServiceBus/ needs Azure.Core >= 1.60.0
• https://www.nuget.org/packages/Azure.Storage.Queues/ needs Azure.Core >= 1.55.0
• https://www.nuget.org/packages/Azure.Storage.Blobs/ needs Azure.Core >= 1.55.0

More Details:

I see that Microsoft.Identity.Web.Certificate still hold a dependency on [Azure.Identity >= 1.17.2](https://www.nuget.org/packages/Azure.Identity/) (>= 1.17.2)

Issue are Azure.Identity 1.17.2 is from April and is missing few things

• Doesn't have a net10.0 target while some SDK have (crossing finger to avoid breaking change is not the best)
• Azure.Identity 1.17.2 depends on Azure.Core 1.50.0 (current is 1.61.0)
• Azure.Identity and Azure.Core made breaking change when moving type from an assembly to another, which in some scenario leads to "type exists in both assembly" ([Azure Dotnet SDK team don't respect semver as we can see here](Azure Dotnet SDK team don't respect semver as we can see here))
• The also didn't list that change as a "breaking change" even though it's one when Dependency have incompatible version of Azure.Core + Azure.Identity at the same time

here's the breaking change:
https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/identity/Azure.Identity/CHANGELOG.md#1210-2026-04-10

All Azure.Identity types have been moved to Azure.Core and are now available through TypeForwardedTo attributes. This is a non-breaking change — existing code continues to work transparently. See the Migration Guide for details.

Here's the migration Guide:
https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/identity/Azure.Identity/MigrationGuide.md

Recomended action: Update either Azure.Identity to 1.21.0 and/or Azure.Core to 1.53.0 (the transitive version of 1.21.0)
