Blazor Server - Login Layout Change

Question

Hello,

In my application, I want to change the layout of the login page like this one here: sign-in So I created LoginLayout.

@inherits LayoutComponentBase  
  
<div class="main">  
    @Body  
</div>  

And added @layout to the login page as follows:

@page  
@layout LoginLayout  
@using Microsoft.AspNetCore.Authorization  
@using Microsoft.AspNetCore.Mvc.TagHelpers  
@using IMS.WebApp.Shared  
@model LoginModel  
@attribute [AllowAnonymous]  
  
@{  
    ViewData["Title"] = "Log in";  
}  
  
<h1>@ViewData["Title"]</h1>  
<div class="row">  
    <div class="col-md-4">  
        <section>  
            <form id="account" method="post">  
                @*<h2>Use a local account to log in.</h2>*@  
                <hr />  
                <div asp-validation-summary="ModelOnly" class="text-danger"></div>  
                <div class="form-floating m-lg-3">  
                    <input asp-for="Input.Email" class="form-control" autocomplete="username" aria-required="true" />  
                    <label asp-for="Input.Email" class="form-label"></label>  
                    <span asp-validation-for="Input.Email" class="text-danger"></span>  
...  

But it gives this error:

The name 'layout' does not exist in the current context  

How can I change the layout of the login page?

Answer 1

Any update @Anonymous ? I don't understand why I can not add layout to login page?

Answer 2

Here is the Login.cshtml just in case;

@page  
@layout LoginLayout  
@using Microsoft.AspNetCore.Authorization  
@using Microsoft.AspNetCore.Mvc.TagHelpers  
@using IMS.WebApp.Shared  
@model LoginModel  
@attribute [AllowAnonymous]  
  
@{  
    ViewData["Title"] = "Log in";  
}  
  
<h1>@ViewData["Title"]</h1>  
<div class="row">  
    <div class="col-md-4">  
        <section>  
            <form id="account" method="post">  
                @*<h2>Use a local account to log in.</h2>*@  
                <hr />  
                <div asp-validation-summary="ModelOnly" class="text-danger"></div>  
                <div class="form-floating m-lg-3">  
                    <input asp-for="Input.Email" class="form-control" autocomplete="username" aria-required="true" />  
                    <label asp-for="Input.Email" class="form-label"></label>  
                    <span asp-validation-for="Input.Email" class="text-danger"></span>
