[BUG] Creating New/Adding projects from subfolders creates solution folders

Describe the Issue

In Visual Studio, when we create new/add existing projects from subfolders, the project opens directly without creating solution folders in solution Explorer.

But In VS Code, it is creating solution folders for each subfolder on the disk.

Creating solution folder might help in some scenarios but not matching with Visual Studio,
For Example: Having a solution folder allow us to create/open projects with identical names, that also only works in Visual Studio

So, there is inconsistency in how we manage projects in Visual Studio and Visual Studio Code.

Steps To Reproduce

Create New Project in a subfolder or Add Existing Project from a subfolder.

Expected Behavior

As this looks like a feature not a bug in one way. I'm not able to decide which one is correct. (Visual Studio or VS Code)

Environment Information

• OS: Windows 11
• VS Code Version: 1.82.2
• Extension: C# Dev Kit v0.4.10

Reproduce creating or adding a project from a subfolder in VS Code with C# Dev Kit, then compare the resulting solution folders with Visual Studio. No source file or test is identified; done requires a documented decision and matching behavior for the two workflows.
