Where should I run git init in a Visual Studio 2022 project with nested folders?

I want to introduce Git into my Visual Studio 2022 project, but where exactly should I place the .git directory (i.e., where should I run git init)?

I created a project called MyTestApp, but for some reason it was created in a nested structure like repos/MyTestApp and repos/MyTestApp/MyTestApp. I’m not sure which of these directories should have the .git repository.

This output was generated by running tree /F /A > filelist.txt in the terminal under "C:\Users\lapislazuli\source":

C:.
|   filelist.txt
|   
\---repos
    +---MyTestApp
        |   MyTestApp.sln
        |   
        \---MyTestApp
            |   App.config
            |   Form1.cs
            |   Form1.Designer.cs
            |   MyTestApp.csproj
            |   Program.cs
            |   
            +---bin
            |   \---Debug
            +---obj
            |   \---Debug
            |       |   .NETFramework,Version=v4.8.AssemblyAttributes.cs
            |       |   DesignTimeResolveAssemblyReferences.cache
            |       |   DesignTimeResolveAssemblyReferencesInput.cache
            |       |   MyTestApp.csproj.AssemblyReference.cache
            |       |   
            |       \---TempPE
            \---Properties
                    AssemblyInfo.cs
                    Resources.Designer.cs
                    Resources.resx
                    Settings.Designer.cs
                    Settings.settings
                    

Exact steps I followed

1. Double-click the Visual Studio icon on the taskbar to start it.
2. The Visual Studio Installer window appears.
3. Click [Launch] for Visual Studio Community 2022.
4. The Visual Studio 2022 window appears.
5. Click [Create a new project].
6. Select [Windows Forms App (.NET Framework)].
7. Click [Next].
8. Click [Create] with the following settings:
   • Project name: MyTestApp
   • Location: C:\Users\lapislazuli\source\repos
   • Solution name: MyTestApp
   • “Place solution and project in the same directory” → unchecked
   • Framework: .NET Framework 4.8

When I checked “Place solution and project in the same directory”, the nested structure did not occur. However, I’m not sure if that’s the correct approach.

Just create version control system here, the solution file also need to be tracked.

repos/
└── MyTestApp/              <-- .git folder here
    ├── .git/
    ├── .gitignore
    ├── MyTestApp.sln
    └── MyTestApp/
        ├── MyTestApp.csproj
        ├── Form1.cs
        └── ...

The nested folder structure is quite common. I don’t use Visual Studio myself, but in VS Code, it also defaults to creating a nested setup, with the project files in a subfolder and the solution file located at the root of the workspace.
