What is vvvv-dotnet?
This skill empowers developers and AI agents to bridge the gap between vvvv gamma and the .NET ecosystem. It provides the technical foundation for creating C# plugins, managing NuGet dependencies, and optimizing performance through SIMD vector types and efficient memory management. By leveraging Openclaw Skills, users can automate the configuration of project files and ensure seamless interoperability between visual nodes and compiled code.
The skill covers essential aspects like target framework selection (net8.0), required assembly attributes for node discovery, and advanced interop strategies. Whether building simple utilities or complex GPU-accelerated plugins, these Openclaw Skills ensure a standard, repeatable workflow for .NET integration.
vvvv-dotnet Use Cases
- Adding NuGet packages to vvvv projects
- Configuring .csproj files for net8.0 compatibility
- Creating high-performance C# plugins for vvvv gamma
- Implementing async patterns to prevent UI blocking
- Managing native resources and IDisposable objects in visual programming
How vvvv-dotnet Works
- Configure the project environment using a .csproj file targeting net8.0 and specific VL core packages.
- Apply the [assembly: ImportAsIs] attribute to ensure nodes are discoverable in the vvvv node browser.
- Define shared logic using C# classes or structs, utilizing ProcessNode attributes for visual integration.
- Use dotnet build to verify compilation and generate the necessary DLLs or source references.
- Integrate the compiled logic into vvvv gamma via live-reload source references or binary package references as part of your Openclaw Skills workflow.
vvvv-dotnet Setup
To begin using this with Openclaw Skills, set up your NuGet.config to include the vvvv teamcity feed and create a standard .csproj.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net8.0</TargetFramework>
<OutputPath Condition="'$(Configuration)'=='Release'">..\\..\\lib\\net8.0\\</OutputPath>
<AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="VL.Core" Version="2025.7.*" />
</ItemGroup>
</Project>
Then, build the project using the CLI:
dotnet build src/MyPlugin.csproj -c Release
vvvv-dotnet Data Schema & Taxonomy
The skill follows a standard .NET project structure optimized for the vvvv environment:
| Component | Description |
|---|---|
| .csproj | Defines dependencies like VL.Core and output paths to lib/net8.0/. |
| NuGet.config | Includes the vvvv TeamCity feed for specialized packages. |
| AssemblyInfo.cs | Contains the [assembly: ImportAsIs] metadata for node discovery. |
| .sdsl files | Shader files that support live-reloading regardless of workflow. |
vvvv-dotnet Advanced Features
- Zero-cost vector interop between Stride and System.Numerics using Unsafe.As for SIMD performance.
- Blittable struct support for high-performance GPU and network data transfer via explicit memory layouts.
- SynchronizationContext handling to safely post background task results back to the vvvv main thread.
- C++/CLI interop capabilities for wrapping native C++ libraries using MSBuild and Visual Studio.
- COM interop management for Direct3D and DXGI resources using ComPtr structures.
