Support for ASP.NET Core Runtime & .NET Runtime 10.0.2 or 10.0.3

Question

According to https://dotnet.microsoft.com/en-us/download/dotnet/10.0, 10.0.3 was released on Feb. 10, 2026 and 10.0.2 was released on Jan. 13, 2026.

In my Azure Web App & Function App, I only see .NET Runtime 10.0.0 installed. Do you have an ETA for having support for 10.0.2 or 10.0.3?

Hi @Hiroshi Tashiro ,

Thank you for reaching out to us regarding your question about the availability of .NET Runtime versions 10.0.2 and 10.0.3 for your Azure Web App and Function App. Currently, you are only seeing version 10.0.0 installed.

Azure App Service and Azure Functions do not publish ETAs for specific .NET minor or patch versions (such as 10.0.2 or 10.0.3).
While .NET 10.0.2 and 10.0.3 are generally available on the public .NET download site, the Azure platform controls when minor and patch updates are rolled out across regions.

According to the official Language runtime support policy for Azure App Service:
“App Service updates existing stacks after they become available from each community. App Service updates major versions of stacks but can’t guarantee any specific minor versions or patch versions. The platform controls minor and patch versions.”

“If you need a specific minor or patch version, use a custom container.”
Reference: Language runtime support policy for Azure App Service

Additionally, Microsoft explains that runtime and OS patching is performed using safe deployment practices and may be delayed or paused to avoid customer impact:

“The latest patches are applied as soon as possible, but patching may be slowed or paused at times to avoid app impacts and outages.”

Reference: OS and runtime patching - Azure App Service | Microsoft Learn

Because of this policy, Azure doesn't commit to or publish ETAs for specific .NET patch versions appearing in the App Service or Function App runtime stacks.

Why you still see .NET 10.0.0:

Patch‑level updates (10.0.2 / 10.0.3) are rolled out by the platform on Azure’s own cadence and may not immediately appear in the runtime selector, even though .NET 10 itself is supported.

Supported options if you need .NET 10.0.2 or 10.0.3 immediately:

If your scenario requires running on a specific .NET patch version, below are the following supported approaches:

• Use a custom container (recommended by policy) A custom Windows or Linux container allows you to choose the exact .NET runtime version you need, including specific patch levels. Configure a custom container for Azure App Service
• Publish your application as self‑contained A self‑contained deployment bundles the .NET runtime with your app, so it doesn’t depend on the platform‑installed runtime version. .NET application publishing overview
