What are Tag Helpers in ASP.NET Core? See Example

Tag Helpers in ASP.NET Core are server-side components that help developers generate HTML dynamically in Razor views. They provide intelligent HTML rendering, reduce boilerplate code, and improve readability. Tag Helpers are easy to use and integrate into MVC or Razor Pages.

Key Features:

• Simplify Razor HTML generation
• Intuitive syntax with HTML-like tags
• Supports forms, links, images, and validation
• Integrated with ASP.NET Core MVC and Razor Pages
• Enhances code maintainability and readability

Example:
Using anchor and form Tag Helpers in a Razor view:

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

<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>

Tag Helpers in ASP.NET Core allow cleaner, more maintainable HTML and provide strong integration with models and routing.
