Windows 2022 image not updating .NET 8 sdk and doesn't include all feature bands

[Styxxy]

Description

Compared to the windows-2019 image, the windows-2022 image doesn't update .NET 8 SDK version nor does it include any of the feature bands (1xx, 2xx, 3xx). This causes the UseDotNet task to always have to download and install the correct .NET SDK (managed through global.json).

Image version and build link

Image: windows-2022
Version: 20240929.1.0
Included Software: https://github.com/actions/runner-images/blob/win22/20240929.1/images/windows/Windows2022-Readme.md
Image Release: https://github.com/actions/runner-images/releases/tag/win22%2F20240929.1

Is it regression?

No

Expected behavior

Have the latest (at image build time) .NET 8 SDK installed as well as the latest patch of each feature band within .NET 8; which is the case in image windows-2019.

When running on vmImage: windows-2019, output of command dotnet --list-sdks:

> dotnet --list-sdks

6.0.133 [C:\Program Files\dotnet\sdk]
6.0.203 [C:\Program Files\dotnet\sdk]
6.0.321 [C:\Program Files\dotnet\sdk]
6.0.425 [C:\Program Files\dotnet\sdk]
7.0.120 [C:\Program Files\dotnet\sdk]

7.0.317 [C:\Program Files\dotnet\sdk]

8.0.206 [C:\Program Files\dotnet\sdk]
8.0.304 [C:\Program Files\dotnet\sdk]
8.0.401 [C:\Program Files\dotnet\sdk]

Actual behavior

All features bands of .NET 6 and .NET 7 are available, with .NET 8 only the default version 8.0.400 (which comes from the Visual Studio 2022 installer) is installed (and not patched!).

It seems like version "8.0" should be added here to make it work:

runner-images/images/windows/toolsets/toolset-2022.json

Lines 315 to 324 in 7bf4ada

	"dotnet": {
	"versions": [
	"6.0",
	"7.0"
	],
	"tools": [
	{ "name": "nbgv", "test": "nbgv --version", "getversion": "nbgv --version" }
	],
	"warmup": false
	},

If comparing to the image toolset definition of windows-2019 it is included there:

runner-images/images/windows/toolsets/toolset-2019.json

Lines 408 to 418 in 7bf4ada

	"dotnet": {
	"versions": [
	"6.0",
	"7.0",
	"8.0"
	],
	"tools": [
	{ "name": "nbgv", "test": "nbgv --version", "getversion": "nbgv --version" }
	],
	"warmup": true
	},

@lakshminarayana02 I think I have the same problem with ubuntu-latest:

Hi @Styxxy , @MarkusRodler,
As pointed out, .Net 8 default version is installed during installation of Visual Studio.
We are in internal discussion as whether to go ahead with other feature bands installation for this version.

Meanwhile, please feel free to use setup-dotnet action as given, in the below workflow snippet -

- name: Setup .NET SDK
     uses: actions/setup-dotnet@v4
     with:
        dotnet-version: | 
          8.0.403
          8.0.306
          8.0.110
