Then Marcus built — a small VB.NET utility that generates repetitive code from simple templates. It saved him 12 hours that week. His boss gave him a bonus. Other devs asked for it. Here is Marcus’s generator, polished and ready for you. The Code: CodeForge.vb (Full Generator) Imports System.Text Imports System.IO ''' <summary> ''' Generates VB.NET boilerplate code from JSON-like definitions. ''' Story: Built to eliminate repetitive CRUD, parsing, and validation code. ''' </summary> Public Class CodeForge
Console.WriteLine("Generation complete. Press any key.") Console.ReadKey() End Sub End Module | Feature | Why It Matters | |--------|----------------| | No external dependencies | Runs on any .NET Framework / .NET Core with VB support. | | Consistent formatting | Produces human-readable, maintainable code. | | Error-aware templates | CSV reader handles missing columns; SQL builder uses parameters (safe). | | Extensible | You can add GenerateValidator , GenerateRepository , etc. | | Self-documenting | Each method clearly names what it builds. | Real-World Extension Idea Marcus later added a JSON schema to VB class converter: Other devs asked for it
Marcus , a junior developer at DataFlow Solutions , was drowning. His boss needed three different CSV parsers, two JSON validators, and a SQL INSERT builder — all by Friday. Writing the same boilerplate ( Try-Catch , Using blocks, List(Of T) loops) over and over was burning his nights.

Want me to generate a specific VB class for your use case (e.g., REST API wrapper, INI parser, DataTable-to-List mapper)? Just describe the repetitive pattern you’re stuck with.
