This PR is targeting main, which is now for .NET 11-facing work. If you intended to target .NET 10, either retarget this PR to release/10.0.1xx or make sure you backport the change to release/10.0.1xx after merging. See #50394 for more details.

@ViktorHofer It looks like the CollatePackageDownloads task is being used during restore, before the sdk tasks are built. Similar issue in the net11 upgrade PR. I'm thinking that the in-tree task usage is not correct here and maybe the issue?

Pull Request Overview

This PR enables the CollatePackageDownloads task by removing conditional logic that was preventing its use. The change removes a temporary condition that was checking if MaxNetVersion differs from TargetingPackPruneVersion, which was likely put in place as a workaround while waiting for SDK updates.

• Removes conditional usage of CollatePackageDownloads task
• Removes unnecessary UsingTask declaration from sdk-tasks targets
• Enables unconditional execution of targeting pack collection for prune data
