Where are the Login and Register pages in an AspNe

问题:

In VS 2017, I created a new ASP.NET Core Web Application. On the second page of the wizard, I chose Web Application, and for Authentication I chose "Individual User Accounts".

Now, I'm trying to find the Pages associated with /Account/Register and /Account/Login.

_Layout.cshtml brings in _LoginPartial.cshtml, much as it did in classic MVC:

<div class="navbar-collapse collapse">
    <ul class="nav navbar-nav">
        <li><a asp-page="/Index">Home</a></li>
        <li><a asp-page="/About">About</a></li>
        <li><a asp-page="/Contact">Contact</a></li>
    </ul>
    <partial name="_LoginPartial" />
</div>

If the user is not signed in then _LoginPartial includes <a> tags that point to the login and register pages:

<ul class="nav navbar-nav navbar-right">
    <li><a asp-area="Identity" asp-page="/Account/Register">Register</a></li>
    <li><a asp-area="Identity" asp-page="/Account/Login">Login</a></li>
</ul>

That all seems to make sense. But I would have expected the Areas folder structure to include the Register and Login folders. It does not. The only thing I find there is _ViewStart.cshtml

I know that the scaffolded code works, When I run the project, the Register link points to "/Identity/Account/Register" and the Login link points to "/Identity/Account/Login". Clicking on the Register link gets me a registration page that includes the text "Create a new account".

But I can't find the text "Create a new account" anywhere in the project.

Can someone tell me what I'm missing?

It was announced during the preview of asp.net core 2.1 that the Identity UI would be moved to a new Razor Class Library. https://blogs.msdn.microsoft.com/webdev/2018/03/02/aspnetcore-2-1-identity-ui/

It is still possible to scaffold the Identity Views into your own project if you prefer local views: https://docs.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity?view=aspnetcore-2.1&tabs=visual-studio

'If you want all the identity code to be in your application so that you can change it however you want, you can use the new identity scaffolder to add the identity code to your application. All the scaffolded identity code is generated in an identity specific area folder so that it remains nicely separated from your application code.'

It works pretty nice and easy for me.

ASP.NET Core 2.1 with Identity automatically includes the "Default UI". It's a Razor Pages class library that's referenced via AddDefaultIdentity in Startup, which under the hood literally calls

If you want the actual files in your project, you need to scaffold them in. Right click your project in the solution explorer and choose Add > New Scaffolded Item... Then, click the Identity listing on the left, and then the Add button. A new window will pop allowing you to select the pages you want included, your context, etc. Configure it how you like and

It's also worth noting, that as long as you use AddDefaultIdentity, the default UI is still included, which means you don't actually need all the scaffolded files if you want any of them. They'll essentially function as overrides. Anything specifically included in your project will be used, while anything that's missing will be pulled from the default UI.

This also means that if you want to do something like use standard controller actions and views instead of Razor Pages, the default UI will still be active, and take precedence. You have to use AddIdentity or AddIdentityCore instead of AddDefaultIdentity if you want the default UI off completely.
