VB.NET Web Development

This section provides comprehensive documentation on developing web applications and services using VB.NET. Explore the various frameworks and technologies available to build robust, scalable, and modern web solutions.

Key Web Development Technologies with VB.NET

ASP.NET Core

ASP.NET Core is a high-performance, open-source, cross-platform framework for building modern, cloud-enabled, internet-connected applications. It's the recommended framework for new web development with VB.NET.

ASP.NET Web Forms (Legacy)

While ASP.NET Core is the future, many existing applications are built using ASP.NET Web Forms. This section covers the fundamentals and advanced topics for maintaining and extending these applications.

Web Services and APIs

Learn how to create and consume web services and APIs, enabling communication between different applications and platforms.

Important: For new projects, it is highly recommended to use ASP.NET Core due to its performance, flexibility, and active development.

Getting Started with Web Development

Here are some essential steps to begin your web development journey with VB.NET:

Install Visual Studio: Ensure you have the latest version of Visual Studio with the ASP.NET and web development workload installed.
Create Your First Project: Start with a simple ASP.NET Core or ASP.NET Web Forms project to understand the basic structure.
Learn the Fundamentals: Familiarize yourself with HTTP, HTML, CSS, JavaScript, and server-side scripting concepts.
Explore Framework Features: Dive into the specific features of ASP.NET Core or Web Forms, such as routing, data access, and UI rendering.

Example: A Simple Web Form

Here's a basic example of a VB.NET Web Forms page:


<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<!DOCTYPE html>
<html>
<head runat="server">
    <title>Welcome</title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:Label ID="lblMessage" runat="server" Text="Hello, World!"></asp:Label>
        </div>
    </form>
</body>
</html>

And its corresponding code-behind (Default.aspx.vb):


Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        ' This code runs when the page is loaded.
        ' You can dynamically set the label text here if needed.
    End Sub
End Class
