Store "Configure Multiple Startup Projects" settings on the SLN file itself

Describe the bug

A new React and ASP.NET Core (TypeScript) solution in VS2022contains separate frontend (esproj) and backend (csproj) projects. To run this and debug it, one must do Solution > Configure Startup Projects > Multiple Startup Projects - and select both to Start. This is configured by default when creating a new solution with this project template. So all of this works fine.

However, we hit a problem when checking this code into source control. The multiple startup projects configuration is NOT stored on the .sln file. Rather it is stored in the .vs/{projectname}/v17/.suo file. Most organizations commit neither the .vs folder nor any *.suo files to source control. This means

1. it is a step that the developer must do every time they checkout code, and
2. it also requires that the dev know how to do this, which as I found not everyone knows.

Expected Behavior

Could we please move this setting to the .sln file itself?
That way it is also tracked in source control.

Anything else?

This is my first issue on ASP.NET Core. So apologies if I'm making it / providing some detail incorrectly.

I'm not sure exactly where this issue should live, I've a hunch it should be a Visual Studio feedback item, but it's not something in the scope of this repository.
