Spotfire C# extension dll not loaded when debugging in the Analyst

I am trying to figure out why my custom extension dll does not get loaded when I start debugging my project - press F5 when using Visual Studio 2019 (same happens with 2017 as well).

My project is pretty much a simple CustomTool (i.e. File -> New Project -> TIBCO Spotfire Extention_VS) which registers a menu item in the Tools menu which when clicked manipulates page locations.

This is where my project is relative to the SDK: 

When the Spotfire Analyst launches, I go to Help -> Support diagnostics and logging -> Product File Information to inspect if the dll (i.e. MapChartCoordinatesCustomToolGeorgi.dll) is loaded correctly, but it doesn't appear to be in the list:

This is my main class:

public sealed class CustomAddIn : AddIn
{
    // Override methods in this class to register your extensions.

    protected override void RegisterTools(ToolRegistrar registrar)
    {
        base.RegisterTools(registrar);
        CustomMenuGroup menuGroup = new CustomMenuGroup("My menu sub group");
        registrar.Register(new PageTool("Georgi's Menu"), menuGroup);
    }
}

This is my PageTool class:

public class PageTool : CustomTool<Page>
{

    public PageTool(string menuText) : base(menuText)
    {
    }


    protected override void ExecuteCore(Page page)
    {
        Document document = page.Context.GetAncestor<Document>();
        int index = document.Pages.IndexOf(page);
        document.Pages.Move(index, document.Pages.Count - 1);
    }


    protected override bool IsEnabledCore(Page page)
    {
        Document document = page.Context.GetAncestor<Document>();

        int index = document.Pages.IndexOf(page);
        return index >= 0 && index < document.Pages.Count - 1;
    }
}
