Setting a new landing page in ASP.NET Core MVC

问题

I need to set a new landing page for my application. For now it is landing on the standard Index.cshtml inside of the Home folder inside of the Views folder. I want my new landing page to be from this directory:

Views/Welcome/Index.cshtml

The error I'm getting says: InvalidOperationException: RenderBody has not been called for the page at '/Views/Welcome/Index.cshtml'. To ignore call IgnoreBody();

I have made the following changes so far in my startup.cs file:

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            services.Configure<RazorViewEngineOptions>(o =>
            {
                o.ViewLocationFormats.Clear();
                o.ViewLocationForms.Add("/Views/Welcome/Index" + RazorViewEngine.ViewExtension);
            });
        }


        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Welcome}/{action=Index}/{id?}");
            });
            endpoints.MapFallbackToController("Index", "Welcome");
        }

My View:

@{
  ViewData["Title"] = "Index";
}

//html
//jQuery

I haven't found any resources online on how to accomplish this when using MVC.

Thanks!

Redirect to other view

If you want to return different view in a simply way, you could try redirecting to other view in Home/Index.

public class HomeController : Controller
{
        public IActionResult Index()
        {
            //return View();
            return View("~/Views/Welcome/Index.cshtml");
        }
 }

Layout

As for the layout, _ViewStart.cshtml(/Pages/Shared) are run before every full view (not layouts, and not partial views).

_ViewStart.cshtml

@{
    Layout = "_Layout";
}

Render JS

In the code below, you define the scripts section and render scripts inside the section.

Index.cshtml

 @RenderSection("Scripts", required: true)

_ValidationScriptsPartial.cshtml

 @section Scripts {
   <script type="text/javascript" src="~/scripts/js1.js"></script>
   <script type="text/javascript" src="~/scripts/js2.js"></script>
   <script type="text/javascript" src="~/scripts/js3.js"></script>
 }

I think I have found a solution. I added Layout = null to my view (the new landing page), but it removed all of my css. I then added the paths to my css libraries inside of this file. It seems to work, but I am still open to any suggestions (if any) on how to improve any of this code. Thanks!

This is how I found my solution: Stackoverflow solution
