For example, if you know about .NET 9.0 but the releases index shows .NET 10.0 as active, use .NET 10.0. ## Inputs - A development machine running macOS, Windows, or Linux - Shell access (Bash on macOS/Linux, PowerShell on Windows) - Internet access for NuGet API queries and SDK downloads - Admin/sudo access may be required for installing SDKs and workloads - **Bash prerequisites**: `curl`, `jq`, and `unzip` (macOS/Linu...
