Advanced Visual Basic 2026 Programming, Volume 1: Professional VB.NET Engineering, Object Modelling, Generics, Events, Design Patterns, and LINQ

Take your Visual Basic skills beyond basic syntax and learn how to build professional, maintainable, and testable VB.NET applications with Visual Studio 2026 and .NET 10.

Advanced Visual Basic 2026 Programming, Volume 1 is a practical guide for developers, students, educators, and experienced Visual Basic programmers who want to understand modern application architecture and professional software-development practices.

Rather than presenting isolated code fragments, this book guides you through the progressive development of an Advanced Order Manager application. Each chapter extends the same solution, allowing you to see how professional applications evolve from simple classes into layered, event-driven, configurable, and testable systems.

Inside this volume, you will learn how to:

organise a solution using Domain, Application, Infrastructure, Windows Forms, and Tests projects;

create entities, value objects, interfaces, and reusable application contracts;

work effectively with generics, collections, and repositories;

use delegates, events, and lambda expressions;

build an event-driven order-processing system;

create reporting, filtering, CSV, JSON, and HTML export features;

generate print previews for business reports;

apply Strategy, Factory, Decorator, and Command design patterns;

use dependency injection with the .NET Generic Host;

manage settings through appsettings.json and strongly typed options;

add structured logging with ILogger;

create a central application startup and composition process;

and write unit and integration tests with MSTest.

Every major concept is supported by clear explanations, step-by-step instructions, complete VB.NET code, troubleshooting guidance, review questions, and practical exercises.

A Complete Hands-On Project Throughout the book, you will build and improve a working Advanced Order Manager application featuring:

configurable order validation and pricing;

standard, priority, and bulk-order calculations;

event-driven processing and audit monitoring;

reporting and summary statistics;

CSV, JSON, and HTML exports;

print-preview support;

design-pattern-based components;

dependency injection;

configuration and logging;

and automated tests.

Source Code Available on GitHub The complete source code for the projects featured in this book is available on GitHub. Chapter tags allow readers to download and examine the solution at different stages of development, making it easier to follow the lessons, compare changes, and troubleshoot their own projects.

This book is suitable for readers who already understand basic Visual Basic programming and are ready to progress toward professional VB.NET application development.

Volume 2 will be available soon , continuing the journey with more advanced topics such as asynchronous programming, concurrency, database development, LINQ, Entity Framework Core, REST APIs, JSON communication, security, testing, performance, and larger hands-on business applications.

Build more than working programs. Learn how to design VB.NET applications that are structured, extensible, reliable, and ready for continued development.
