Key Announcements

Service Fabric version 9.1CU2 introduces programming model support for .NET 7.0. Service Fabric applications running on .NET 6.0 can now be upgraded to .NET 7.0.
Note: Please install the .Net 7 runtime version greater than 7.0.2 which contains fix for binary-deserialization of float/doubles in DataContractSerializer. For details see: Binary-deserialization of float/doubles fix
Azure Service Fabric introduced a policy which will validate that the minimum virtual machine count configuration meets the durability requirements for "Silver" and "Gold." This has been a documented requirement to ensure reliable and safe infrastructure updates can occur for production workloads. Per this policy, Service Fabric Resource Provider node types with virtual machine scale set "Silver" or "Gold" durability tiers should always have at least 5 virtual machines. Any configuration with less than 5 virtual machines leads to various reliability issues while performing infrastructure updates (such as AutoOSUpgrades, scale out/in, platform updates, etc.) and can lead to availability or data loss. Update all of your existing/new deployments to have at least 5 virtual machine instances when the virtual machine scale set durability tier is "Silver" or "Gold." We have blocked operations for new cluster creation of "Silver" and "Gold" durability tier virtual machine scale sets when the target instance count is less than 5 starting February 2023. For more updates or information on this policy and upcoming virtual machine scale set validations, refer to our documentation.

Service Fabric Feature and Bug Fixes

This release includes quality improvements only and does not contain bug fixes to specific issue.

Retirement and Deprecation Path Callouts

As aligned with Microsoft .NET and .NET Core - Microsoft Lifecycle | Microsoft Learn, SF Runtime has dropped support for Net Core 3.1 as of December 2022. For supported versions see Service Fabric supported Linux versions and migrate applications as needed.
Ubuntu 18.04 LTS will reach its 5-year end-of-life window on April 30, 2023. Service Fabric runtime will drop support for 18.04 LTS after the published date, and we recommend moving your clusters and applications to supported versions listed here: Service Fabric supported Linux versions
Service Fabric runtime will soon stop supporting BinaryFormatter based remoting exception serialization by default and move to using Data Contract Serialization (DCS) based remoting exception serialization by default. Current applications using it will continue to work as-is, but Service Fabric strongly recommends moving to using Data Contract Serialization (DCS) based remoting exception instead.
Service Fabric runtime will soon be archiving and removing Service Fabric runtime version 6.4 packages and older, as well as SDK version 3.3 packages and older from the package Download Center. Archiving/Removing will affect application scaling and re-imaging of virtual machines in a Service Fabric Cluster running on unsupported versions. After older versions are removed/archived, this may cause failure while rolling back when the current in-progress upgrade has errors.
Migrate Azure Active Directory Authentication Library (ADAL) library to Microsoft Authentication Library (MSAL) library, since ADAL will be out of support after December 2022. This will impact customers using AAD for authentication in Service Fabric for below features:
- Powershell, StandAlone Service Fabric Explorer(SFX), TokenValicationService
- FabricBRS using AAD for keyvault authentication
- KeyVaultWrapper
- ms.test.winfabric.current test framework
- KXM tool
- AzureClusterDeployer tool
For more information see: [MSAL Migration] (https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-migration)
