What problem does it solve? Installing preview or specific .NET SDK versions system-wide risks breaking existing projects and is hard to revert. This Skill installs a .NET SDK into a project-local .dotnet/ directory and wires it up via the global.json paths feature, leaving the system-wide installation untouched. ## Core Features & Use Cases - Isolated SDK Installation: Downloads and installs any .NET SDK channel, quality, or exact version into .dotnet/ using the official dotnet-install scripts on macOS, Linux, or Windows. - global.json Configuration: Creates or merges the sdk section with version, rollForward, allowPrerelease, and paths settings while preserving existing properties. - Team & CI Scripts: Generates install-dotnet.sh and install-dotnet.ps1 so teammates and CI pipelines can reproduce the exact SDK setup. - Use Case: You want to test a .NET 11 preview with the MAUI workload without touching your stable system SDK. The Skill installs the preview locally, pins it in global.json, gitignores .dotnet/, and installs the workload using the local dotnet binary. ## Quick Start Ask the assistant to install the latest .NET 11 preview SDK locally for this project and configure global.json to use it.
