Make sure to select your preferred development language at the top of the article. ::: zone pivot="programming-language-csharp" The following table shows the .NET versions supported by Azure Functions.
The supported version of .NET depends on both your Functions runtime version and your selected execution model.
Your function app code runs in a separate .NET worker process. Use with supported versions of .NET and .NET Framework. For more information, see Guide for running C# Azure Functions in the isolated worker model.
[!INCLUDE functions-in-process-model-retirement-note]
Your function app code runs in the same process as the Functions host process. This model supports only Long Term Support (LTS) versions of .NET. For more information, see Develop C# class library functions using Azure Functions.
| Supported version | Support level | Expected end-of-support date |
|---|---|---|
| .NET 8 (LTS) | GA | November 10, 2026 |
.NET 6 was previously supported by the in-process model but reached the end of official support on November 12, 2024.
Important
The in-process model currently only supports .NET 8. To be able to update your function app to use a later .NET version, you must migrate to the isolated worker model.
For more information, see Develop C# class library functions using Azure Functions and Azure Functions legacy C# script (.csx) developer reference.
[!INCLUDE functions-runtime-1x-retirement-note]
| Supported version | Support level | Expected end-of-support date |
|---|---|---|
| .NET Framework 4.8.1 | GA | See .NET Framework Support Policy. |
For more information, see Develop C# class library functions using Azure Functions and Azure Functions legacy C# script (.csx) developer reference.
| Supported version | Support level | Expected end-of-support date |
|---|---|---|
| .NET 10 | GA | November 14, 2028. |
| .NET 9 | GA | November 10, 20261 |
| .NET 8 | GA | November 10, 2026 |
| .NET Framework 4.8.1 | GA | See .NET Framework Support Policy. |
1 .NET 9 previously had an expected end-of-support date of May 12, 2026. During the .NET 9 service window, the .NET team extended support for STS versions to 24 months, starting with .NET 9. For more information, see the blog post.
Note
.NET 9 is the last .NET version supported for Linux Consumption plan apps. Newer .NET versions aren't added to Linux Consumption. For more information, see Migrate Consumption plan apps to the Flex Consumption plan.
.NET 6 was previously supported by the isolated worker model but reached the end of official support on November 12, 2024.
.NET 7 was previously supported by the isolated worker model but reached the end of official support on May 14, 2024.
For more information, see Guide for running C# Azure Functions in the isolated worker model.
Version 1.x of the Functions runtime doesn't support running C# function apps in an isolated worker process. Go to the In-process tab or the v4.x tab.
