Getting right view from two razor libraries

Question

I'm writing ASPNET Core web page.
I created two razor view libraries and in each one I created file List.cshtml and controller:
WebPage.Users
List.cshtml
UsersController.cs
WebPage.Clients
List.cshtml
ClientsController.cs

Both controllers have Index method:

public class ClientsViewController : Controller
{
    public IActionResult Index()
    {
        return this.View("~/Pages/Views/List.cshtml");
    }
}

public class UsersViewController : Controller
{
    public IActionResult Index()
    {
        return this.View("~/Pages/Views/List.cshtml");
    }
}

StartUp code:

 public void ConfigureServices(IServiceCollection services)
 {
        services.AddControllersWithViews();

        services.AddMvc()
            .AddApplicationPart(typeof(UsersController).Assembly)
            .AddApplicationPart(typeof(ClientsController).Assembly);
 }

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthorization();
        app.UseEndpoints(endpoints =>{
            endpoints.MapControllerRoute(
                name: "usersViewController",
                pattern: "modules/users/{action}",
                defaults: new {
                    controller = "UsersView",
                    action = "Index"
                });
            endpoints.MapControllerRoute(
                name: "clientsViewController",
                pattern: "modules/clients/{action}",
                defaults: new {
                    controller = "ClientsView",
                    action = "Index"
                });
        });
     }

Now the problem is when I open page "modules/clients/" in browser
it returns view from WebPage.Users.Views. I want to return view from WebPage.Clients.Views assembly.
How can I do this?

Answer 1

Thanks for comment.
There is view "~/Pages/Views/List.cshtml" in both assemblies.

Expected result is:
ClientsViewController should return view from assembly WebPage.Clients.Views.
UsersViewController should return view from assembly WebPage.Users.Views.

Is there a way to accomplish that? Renaming/changing path is not an option.

Hi, @Niki Kante ,

We can see the reasons from the description of Razor Class Library.

Override views, partial views, and pages

When a view, partial view, or Razor Page is found in both the web app and the RCL, the Razor markup (.cshtml file) in the web app takes precedence. For example, add WebApp1/Areas/MyFeature/Pages/Page1.cshtml to WebApp1, and Page1 in the WebApp1 will take precedence over Page1 in the RCL.

You could use Area to separate these two RCLs.
