Razor Pages Default Page in aspnetcore 2

Question

By default a Razor Page app goes to Home/Index

Is there a way to change this to Home/App?

This is quite easy in MVC, but Razor pages using a different routing setup and thus MVC routing does not apply.

I would think it would be in options somewhere, but I don't see it:

services.AddMvc()
            .AddRazorPagesOptions(options =>
            {
                options.Conventions.AuthorizeFolder("/Account/Manage");
                options.Conventions.AuthorizePage("/Account/Logout");
                options. ??SetDefaultPage??
            });

I have tried this:

options.Conventions.AddPageRoute("/App", "");

But now two default routes are found and an error is generated:

AmbiguousActionException: Multiple actions matched. The following actions matched route data and had all constraints satisfied:

Page: /App

Page: /Index

It's possible to resolve this error by removing Pages/Index.cshtml from the project, but I wanted to keep that page as well.

Answer 1

In my case the ambiguity was caused by Pages/Index.cshtml left in project. This worked:

1. options.Conventions.AddPageRoute("/App", "");
2. remove or rename Pages/Index.cshtml
