What are Tag Helper Attributes in ASP.NET Core?

Tag Helper Attributes in ASP.NET Core allow developers to control the behavior of HTML elements in Razor views. They extend HTML with server-side functionality, making it easier to bind data, generate links, and handle forms.

Key Features:

• Adds dynamic behavior to HTML tags
• Supports binding with models and controllers
• Simplifies form generation and validation
• Works seamlessly with built-in and custom Tag Helpers
• Improves readability and maintainability

Example:
Using asp-for and asp-action attributes:

<form asp-controller="Account" asp-action="Login" method="post">
    <input asp-for="Username" />
    <input asp-for="Password" type="password" />
    <button type="submit">Login</button>
</form>

<a asp-controller="Home" asp-action="Index">Home</a>

Tag Helper Attributes in ASP.NET Core enhance HTML elements by connecting them directly to server-side logic, improving productivity and reducing boilerplate code.
