Generally Available: Azure Functions .NET 10 support

Generally Available: Azure Functions .NET 10 support

Azure Functions support for .NET 10 is generally available, enabling production use of the latest .NET runtime for serverless applications. This support was introduced as part of the Azure Functions Ignite 2025 updates.

.NET 10 is supported using the isolated worker model across all Linux and Windows Azure Functions hosting plans, except Linux Consumption. This release enables workloads to take advantage of the latest .NET platform improvements while continuing to use the Azure Functions programming model.

As part of this release, .NET 10 is supported only with the isolated worker model. The legacy in‑process model is not supported. As the Linux Consumption plan is being retired, workloads running on Linux Consumption should be migrated to the Flex Consumption plan, which supports .NET 10 using the isolated worker model. Migration guidance is available in the Azure Functions documentation.

Generally Available: Quota and deployment troubleshooting tools for Azure Functions Flex Consumption

Azure Functions Flex Consumption introduces new platform‑integrated tools that provide clearer insight into quota availability and deployment behavior.

The quota troubleshooting experience surfaces Flex Consumption quota limits and related constraints, helping distinguish between platform‑level limits and application configuration issues when evaluating scale behavior.

The deployment and troubleshooting experience provides richer diagnostics for Flex Consumption deployments, surfacing actionable signals when deployments fail or encounter validation, configuration, or readiness issues.

Together, these tools improve operational visibility and reduce friction when deploying and operating workloads on the Flex Consumption plan.

The Flex Consumption Quota and Flex Consumption Deployment tools are available in the Azure portal under Diagnose and solve problems.

Public Preview: Cluster mode for the agentic CLI for AKS
Users often face security and manageability challenges when diagnostic agents inherit broad user permissions, such as cluster-admin rights, and when each user must deploy their own instance. Cluster mode for the agentic CLI for AKS, now in public preview, brings expert-level AI diagnostics directly into your AKS cluster with tighter security controls and faster performance. This gives teams a shared, always‑available AI assistant that understands real cluster state, correlates signals across Kubernetes and Azure, and can guide troubleshooting or remediation using live data pulled in a secure and managed way. Cluster mode provides the following benefits over the existing client-side experience:

• Fine-grained RBAC control with Azure and Kubernetes RBAC
• Shared AKS Agent instances deployed to a namespace of your choosing
• Faster CVE detection and fixes with a centrally managed image, sourced from MCR

Public Preview: Unified tooling in the AKS MCP server
Managing AKS MCP servers can be affected by the number of tools and the amount of context required, which can increase latency and cost. The unified tooling for the AKS MCP Server introduces two new tools in public preview, call_az and call_kubectl, that enable agents to access cluster data through Azure APIs and kubectl. These tools consolidate existing capabilities and reduce the total number of tools in the AKS MCP by 30%.

The open-ended nature of these tools also brings power back to your AI agent, allowing them to customize and call any kubectl or Azure API command of their choosing rather than being restrained by tightly-defined tools. The new tools are available starting from v0.0.12 of the AKS MCP server.

Generally Available: Anthropic Claude Sonnet 4.6 is now available on Azure Databricks

Azure Databricks now supports Anthropic Claude Sonnet 4.6 through Azure Databricks AI Model Serving. Claude Sonnet 4.6 delivers frontier-level performance on complex coding, agentic workflows, and professional knowledge work including reasoning at a lower price point. The model combines fast responses with controllable, extended “thinking” for hard problems, improving deep reasoning, long-context understanding, and reliability over earlier Sonnet versions.

Claude Sonnet 4.6 is ideal for teams building AI agents, developers needing advanced code assistance across large, multi-language codebases, and enterprises running complex analytical and research workloads over proprietary data in Azure Databricks. The model runs securely within the Azure Databricks environment with access available through pay‑per‑token Foundation Model APIs and (where enabled) provisioned or workspace-level throughput options in supported regions.

Generally Available: Node auto-provisioning support in Azure government and private cloud
Node auto‑provisioning removes the need for teams to manually size and manage compute resources for Kubernetes workloads. Azure Kubernetes Service (AKS) now provides general availability support for node auto‑provisioning in Azure Government and private cloud environments. This capability automatically provisions, manages, and scales compute nodes based on workload requirements. It helps technical practitioners reduce operational overhead, improve resource utilization, and maintain consistent performance without manual intervention

Generally Available: Node auto-provisioning enabled clusters in AKS now support LocalDNS
Customers previously could not enable LocalDNS on clusters that used Node auto‑provisioning in AKS, limiting their ability to use this feature in those environments. LocalDNS is now generally available for AKS clusters with Node auto‑provisioning, providing DNS resolution capabilities within the cluster.

Generally Available: Encryption at host & disk encryption sets support in node auto-provisioning
Node auto-provisioning enabled clusters previously did not have support for Encryption at Host and disk encryption sets. This limited users with certain security requirements for their cluster to not be able to use node auto-provisioning.

Node auto-provisioning now includes support for both Encryption at Host and disk encryption sets. This enables customers to use node auto-provisioning while meeting required encryption controls and gaining its associated compute efficiency, resiliency, and cost-management benefits.

Generally Available: Instant access support for incremental snapshots of Azure Premium SSD v2 and Ultra Disk

Announcing the General Availability of instant access support for incremental snapshots of Premium SSD v2 (Pv2) and Ultra Disk. This new capability enables you to restore new disks immediately after creating snapshots of Pv2 and Ultra disks. Newly restored disks deliver high performance instantly, while data hydration continues rapidly in the background.
Instant access snapshots accelerate backup and recovery workflows, enabling faster environment refreshes and rapid scaling. Common use cases include:

• Create instant backups before software updates and revert quickly if needed.
• Quickly scale stateful applications by creating multiple copies of primary data for new instances, such as adding read-only SQL Server replicas.
• Rapid nightly refresh of training or testing environments from the production.

Instant access support for incremental snapshots of Pv2 and Ultra Disk is available in all public regions where Premium SSD v2 and Ultra Disk are supported. For pricing details, please visit Managed Disk Pricing.
