"configuration.dotnet.projects.loadOnDemand": "Loads projects when a language feature first requests a file they contain instead of loading every project at startup.",
"configuration.dotnet.projects.loadOnDemand": "Discovers and loads projects when you open C# files",

"when a language feature first requests a file" was a bit pithy.

"configuration.dotnet.projects.enableFileBasedPrograms": "Enables the \"file-based programs\" (dotnet run app.cs) experience.",
"configuration.dotnet.projects.enableFileBasedProgramsWhenAmbiguous": "Enables the \"file-based programs\" (dotnet run app.cs) experience in files where the editor is unable to determine with certainty whether the file is a file-based program. Only respected when `dotnet.projects.enableFileBasedPrograms` is `true`.",
