Vb Code Generator -

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:

sb.AppendLine($" Private fieldName As dataType") sb.AppendLine($" Public Property propName() As dataType") sb.AppendLine(" Get") sb.AppendLine($" Return fieldName") sb.AppendLine(" End Get") sb.AppendLine(" Set(value As dataType)") sb.AppendLine($" fieldName = value") sb.AppendLine(" End Set") sb.AppendLine(" End Property") sb.AppendLine() Next vb code generator

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.
