Nuget UpdateArtifacts fails if global.json is present

How are you running Renovate?

A Mend.io-hosted app

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

I'm running a dotnet repo with a global.json and configured to generate locks file via

                <RestorePackagesWithLockFile>true</RestorePackagesWithLockFile>
		<RestoreLockedMode>true</RestoreLockedMode>

global.json specify .net8 (v 8.0.404) but Renovate Bot proceeds to install net9.0 and then try executing dotnet new in the working folder. That fails, correctly, as running dotnet new respects the local global.json.

Assumption is that resolution requires either to run the dotnet new in another folder or installing the sdk version configured in the global.json.

I cannot change the global.json, is there a way to instruct Renovate to use net8 via renovate.json?

Hi there,

Get your discussion fixed faster by creating a minimal reproduction. This means a repository dedicated to reproducing this issue with the minimal dependencies and config possible.

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

Please follow these steps:

1. Read our guide on creating a minimal reproduction.
2. Go to our minimal reproduction template repository.
3. Select the Use this template button to create a new repository based on the template.
4. Work on the minimal reproduction in your own repository.
5. Fill out the information in your repository's README.md.
6. Add the link to your reproduction to the first post of your Discussion. If you are not the original author, you can post a new comment with the link.

If you need help with running renovate on your minimal reproduction repository, please refer to our Running Renovate guide.
Good luck,

The Renovate team

it seems we should start extract dotnet version from an optional global.json inside the repo.

Is there any workaround I can use? is it possible to configure the dotnet version in renovate.json?

As it stand now, I've to disable Renovate as we're not planning to upgrade to .net9 (non-LTS) at all.
