Your code is OK, But you need to pass some data into Partial View when you use it in _Layout.cshtml , Refer to this simple demo:

@{
        var partialModel = new List<MainMenuTable>()
        {
            new MainMenuTable
            {
                Title = "HomePage",
                Link = "index"
            },
            new MainMenuTable
            {
                Title = "PrivacyPage",
                Link = "Privacy"
            }
        };
    }

    <partial name="_MainMenu" model="partialModel"/>

When you don't pass any data into Partival View , It will not show in your _Layout .
