Retiring of the WindowsAzure.ServiceBus nuget package by 30 September 2026 (Azure WCF Relay)

[timucindursun]

We frequently use the "Azure WCF Relay" service and "WindowsAzure.ServiceBus" nuget package in our .NET Framework projects. It seems that we may not be able to easily port our projects to .NET (v6/v8) in the near future.

We received a notification that "WindowsAzure.ServiceBus" will be retired/obsolete by 30 September 2026, and we have no clear path for our old projects. Azure Notification says, "Azure WCF Relay still uses this library, and support of this library in combination with this service will continue until further notice."

Could you guide us and provide a clear response and any references that can help us take necessary actions from today?

Thanks.
