.NET 8 approaches end of support in November 2026. Move the build and development environment to .NET 10 while preserving the existing runtime targets. Similarly the PowerShell version 7.4 and 7.5 (that uses .NET 8 and 9, respectively) go out of support so increasing minimum PowerShell version support to 7.6. It had to be 7.6.6 and not 7.6.9 because CI runners still use 7.6.6, this can be updated later closer to release time.

  • SDK pin: Set global.json to .NET SDK 10.0.401, retaining feature-band roll-forward. 
    {
  "sdk": {
    "version": "10.0.401",
    "rollForward": "latestFeature"
  }
}
  • Developer environment: Update the devcontainer image and label, and refresh the README SDK and Visual Studio requirements.
  • Fixes Update the build to use .NET 10 #2195

Windows CI is failing because Microsoft.WindowsDesktop.App.Ref lacks an exact nuget.org mapping, causing version 8.0.33 to restore from the Azure feed and fail with HTTP 401.

Copilot upgrading .NET from 8 to 10 also means upgrading the minimum supported version of PowerShell 7 version from 7.4 to 6.6 as we have tests for that in our manifest script (.psdm1 file). Please update it and other places that referenced PowerShell 7.4

Updated the module loader minimum to PowerShell 7.6.6 in b0be65a. I kept the SMA 7.4.14 reference because SMA 7.6.6 targets only net10, while this project retains its net8 target; the net8 Engine build and focused tests pass.

Copilot why not powershell 7.6.9? it's latest powershell version and by the time psscriptanalyzer releases it would've been out for long enough as guidance is to update powershell within a month after release of patch.

alos, I think we should update SMA reference and update everyting that targets net8 to net10 because net10 is implicitly the minomum .NET version due to the minimumm PowerShell 7 upgrade to 7.6

Updated to PowerShell/SMA 7.6.9 and retargeted the Engine and Rules projects plus the PowerShell 7 build selection to .NET 10.0, while retaining the net462 and netstandard2.0 targets. Changes are in 4b51b00; the full solution builds in Debug and Release.

Lowered the loader minimum to PowerShell 7.6.6 in commit 97a151e and verified the version gate passes on 7.6.6.
