✨ What is VeloxDev?

VeloxDev gives .NET developers a complete foundation for building interactive workflow editors — the kind where users drag nodes, wire slots together, and watch data flow through a graph at runtime.

The workflow system is the core. Everything else exists to make workflows more extensible, more polished, and AI-controllable:

📦 Installation

Pick the adapter for your GUI framework and you get everything — workflow, agent, animations, and theming wired up for that platform.

Platform adapter packages (recommended)

Platform	Package	NuGet
WPF	VeloxDev.WPF
Avalonia	VeloxDev.Avalonia
WinUI	VeloxDev.WinUI
MAUI	VeloxDev.MAUI
WinForms	VeloxDev.WinForms

Build a WPF workflow view suite with the CLI

Run these commands from an existing WPF project. Replace MyApp with the project's root namespace:

dotnet new install VeloxDev.WPF.Templates
dotnet add package VeloxDev.WPF

dotnet new wpf-v-slot -n SlotView -ns MyApp.Views -o Views
dotnet new wpf-v-node -n NodeView -ns MyApp.Views -o Views
dotnet new wpf-v-link -n LinkView -ns MyApp.Views -o Views
dotnet new wpf-v-selector -n TemplateSelector -ns MyApp.Views -o Views
dotnet new wpf-v-decorator -n GridDecorator -ns MyApp.Views -o Views
dotnet new wpf-v-tree -n TreeView -ns MyApp.Views -o Views

dotnet build

The template package contains the Node, Slot, Link, Tree, template selector, and grid decorator views. Each view template generates its XAML and code-behind files with the required VeloxDev workflow behaviors already connected.

The Avalonia, WPF, WinUI, and MAUI template suites expose the same style options. Common short aliases include:

All templates use -ns for the generated namespace.

Core-only packages (bring your own adapter)

Package	NuGet	Description
VeloxDev.Core		Workflow abstractions, MVVM generators, and runtime models — zero third-party dependencies
VeloxDev.Core.Extension		MAF-based Workflow Agent tools and additional runtime extensions

🚀 Quick Look

Define a node

// Declare a node — the Source Generator handles INotifyPropertyChanged,
// slot lifecycle, and command wiring automatically.
[WorkflowBuilder.Node<MyNodeHelper>]
public partial class MyNodeViewModel
{
    public MyNodeViewModel() => InitializeWorkflow();

    [AgentContext(AgentLanguages.English, "Input slot (receiver)")]
    [VeloxProperty] public partial MySlotViewModel InputSlot { get; set; }

    [AgentContext(AgentLanguages.English, "Output slot (sender)")]
    [VeloxProperty] public partial MySlotViewModel OutputSlot { get; set; }

    [AgentContext(AgentLanguages.English, "Display title shown in the node header")]
    [VeloxProperty] private string title = "My Node";
}

Let an AI control the workflow at runtime

// One fluent call wires up discovery, tools, and the agent session.
var scope = tree.AsAgentScope()
    .WithAutoDiscovery(assemblyName: "MyApp")
    .WithInteractionSafety(3)          // confirm before destructive ops; present choices via tool
    .WithSelectionHandler(ShowDialog)
    .WithConfirmationHandler(ShowDialog);

var agent = chatClient.AsAIAgent(
    instructions: scope.ProvideProgressiveContextPrompt(),
    tools: scope.ProvideTools());

The agent can then create nodes, wire slots, change routing credentials, and patch properties — all through natural-language instructions, with full undo/redo support.
