The .NET SDK uses this variable to help tools that run during .NET SDK commands ensure they use the same `dotnet` host configuration for any child `dotnet` processes they create for the duration of the command. Tools and any MSBuild logic that run within a build and invoke binaries via the `dotnet` host are expected to honor this environment variable to ensure a consistent experience.
