I want to create a page where I can be adding new articles, update articles and display date and time when an article has been updated or added.

Simple Blog Tutorial with example in ASP.Net using C# and VB.Net

I tried the link it inserted into database and displayed the article list but when I clicked on the article list it said "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable"

Could it be that here in the Global.asax file the "slug" is spelled in small letters.

static void RegisterRoutes(RouteCollection routes)
{
    routes.MapPageRoute("DisplayBlog", "Blogs/{BlogId}/{Slug}.aspx", "~/DisplayBlog.aspx");
}
