hhe common way to use view components

Inside of Shared folder you have to crate a Components folder and then MainFooter folder. Create the partial view MainFooter.cshtml there

@model string

<div>

    <p>@Model</p>
</div>

Create class in a Controllers folder

[ViewComponent(Name = "MainFooter")]
public class MainFooterViewComponent : ViewComponent
{
public IViewComponentResult Invoke()
{
 string lastUpdateTime = System.IO.File.ReadAllText("./last.txt");

return View("MainFooter", lastUpdateTime );
}

Layout or main view

<div> @(await Component.InvokeAsync("MainFooter")) </div>
