To design a login form in .NET 7 technology, you will need to:
Create a new project. You can create a new project in Visual Studio by selecting "File" > "New" > "Project". In the "New Project" dialog, select the "ASP.NET Core Web Application" template and click "Next".Add a controller. In the "Add New Item" dialog, select the "Controller" template and click "Add". Name the controller "LoginController".Add an action method. In the "LoginController" class, add an action method named "Login". The following code shows the basic structure of the "Login" action method:
Code snippet
public async Taskandlt;IActionResult> Login(string username, string password)
{
    // Validate the username and password.
    // If the username and password are valid, log the user in.
    // If the username and password are not valid, return an error message.
}
Add a view. In the "Views" folder, add a new view named "Login.cshtml". The following code shows the basic structure of the "Login.cshtml" view:
Code snippet
@model AppName.Models.User
andlt;form action="/login" method="post">
    andlt;div>
        andlt;label for="username">Usernameandlt;/label>
        andlt;input type="text" id="username" name="username" />
    andlt;/div>
    andlt;div>
        andlt;label for="password">Passwordandlt;/label>
        andlt;input type="password" id="password" name="password" />
    andlt;/div>
    andlt;input type="submit" value="Login" />
andlt;/form>
Configure authentication. In the "Startup" class, configure authentication. The following code shows how to configure authentication to use a database:
Code snippet
services.AddAuthentication(options =>
{
    options.DefaultScheme = "Db";
    options.DefaultSignInScheme = "Db";
    services.AddDbContextandlt;ApplicationDbContext>(options =>
    {
        options.UseSqlServer("Server=localhost;Database=mydatabase;Integrated Security=True;");
    });
    services.AddIdentityandlt;User, string>(options =>
    {
        options.SignInScheme = "Db";
        options.PasswordScheme = "Db";
    });
    services.AddAuthentication(options =>
    {
        options.DefaultScheme = "Db";
        options.DefaultSignInScheme = "Db";
    });
});
Run the application. In Visual Studio, press F5 to run the application. The application will open in a new browser window.
Test the login form. Enter a valid username and password in the login form and click the "Login" button. If the username and password are valid, the user will be logged in and the application will redirect to the home page. If the username and password are not valid, the user will see an error message.
Here are some additional tips for designing a login form in .NET 7 technology:
Use a consistent design throughout the form.Use clear and concise labels for all of the form fields.Make sure that the form fields are large enough to enter the required information.Use a validation mechanism to ensure that the user enters valid information in the form fields.Use a secure password hashing algorithm to store passwords in the database.
