VisioAutomation

VisioAutomation is an open-source suite of .NET libraries and tools designed to dramatically simplify the programmatic control and creation of Microsoft Visio diagrams. Created and maintained by developer Saveen Reddy, the project eliminates the verbose, clunky boilerplate code typically required when interacting with the native Visio COM/Interop API.

By providing high-level wrappers and a dedicated scripting facade, it enables developers to generate network diagrams, org charts, and floor plans via concise scripts instead of manual dragging and dropping. The Main Components

The project is modularized into a few core ecosystems depending on your chosen development stack:

VisioAutomation2010 (.NET Library): The bedrock library available on NuGet. It handles the heavy lifting of shape placement, text formatting, and routing connections.

Visio PowerShell Module: Hosted on the PowerShell Gallery, this wraps the .NET library into friendly admin cmdlets. It allows system administrators to spin up real-time hardware architecture diagrams using simple shell scripts.

VisioAutomation.VDX: A standalone sub-library that enables the generation of raw Visio XML (VDX) files from scratch. Crucially, it does this without requiring Microsoft Visio to be installed on the machine, making it perfect for server-side automated reports. C# vs. PowerShell Implementation

The framework introduces a highly clean syntax approach. Instead of digging deep into complex nested object properties, look at how easily you can draw a custom rectangle and bind data text to it: Environment Sample Syntax / Commands C# (.NET)

var client = new VisioScripting.Client(visio);client.Draw.DrawRectangle(TargetPage.Auto, new Rectangle(0, 0, 4, 2));client.Text.SetShapeText(TargetShapes.Auto, new[] { “Hello, Visio!” }); PowerShell
