Worked on improving the reliability of Windows .NET SDK installations in the jdx/mise repository by addressing a persistent installation failure affecting both developers and CI environments. Focused on scripting and Windows development using Lua, the solution involved replacing cmd.exec() with os.execute() to ensure the dotnet-install.ps1 script executed correctly without interference from stdout or stderr capture. This change was validated through manual Windows testing and consistent verification of dotnet version outputs, aligning with established patterns for robust script execution. The work enhanced installation scripting practices and reduced CI failures, contributing to more stable and predictable Windows development workflows.
