VCI4 .NET Wrapper


This project contains the source of the VCI4 .NET Wrapper (VCI4 = Virtual Communication Interface Version 4), a component that provides access to the VCI4 C++-API. VCI4 is a driver/application framework to access HMS CAN or LIN interfaces on the Windows OS, for details see https://www.ixxat.com/technical-support/support/windows-driver-software

This package is released as a binary package via NuGet for application developers, for details see https://www.nuget.org/packages/Ixxat.Vci4 There is also a strong named variant which is available from https://www.nuget.org/packages/Ixxat.Vci4.StrongName

Open source

The main purpose to release this component as open source is to give application developers a better insight into the internal workings of the component. As it is mostly a 1:1 wrapper to the underlying VCI4 C++-API there is little encoded functionality, nethertheless access to the source could help clarify unclear behaviour or help detect bugs.

Developers which need more control could alter the component or use it as a template to implement their own device access component on top of the VCI4 C++-API.

For users

See the user documentation in /doc/README.md

For developers

The component is split into three parts:

  • a contract assembly (interface declaration assembly)
  • a loader
  • a managed C++ implementation

The C++ part is compiled twice to x86 and x64 targets. A .NET application only references the loader and the contract assembly and could therefore be kept target agnostic (AnyCPU). The loader checks the platform and loads the corresponding target specific assembly.

To compile the component start a Powershell console and execute

PS> .\build.ps1 -Version=4.1.0

If you want to create a strong named version add the AssemblyKeyFile parameter

PS> .\build.ps1 -Version=4.1.0 -AssemblyKeyFile=mykeyfile.snk

For more information have a look at the build script .\build.ps1 and the msbuild project .\vci4net.prj.


  • VisualStudio 2022
  • nuget.exe client version 6.3.0
  • Sandcastle Help File Builder version 2021.11.7.0

The VCI4 .NET wrapper sits on top of the VCI4 C++ API so you need the VCI4 driver setup installed.

Resolved issues:
- Use correct value to initialize CANBTRTABLE.bIndex attribute before calling ICanControl::DetectBaud()
- Add mstest based unittests
- Move msgfactory creation to the VciServerImpl ctor as it should not depend on the load state of the vciapi.dll
