Hello! It's great to hear that you've successfully trained and used your model with ONNX and C#. For integrating OpenVino with C#, you might need to adjust your approach since direct support can be limited.

For using OpenVino in C#, you generally need to use the OpenVino Runtime which is primarily designed for C++ and Python. However, you can create a C++ DLL that wraps the OpenVino functionality and then use P/Invoke in C# to call the functions from this DLL.

Here’s a very basic outline of the steps:

1. Create a C++ DLL that loads the OpenVino model and performs inference.
2. Use P/Invoke in C# to interact with the DLL.

C++ DLL example (simplified):

extern "C" __declspec(dllexport) int LoadModel(const char* modelPath) {
    // Load model with OpenVino here
    return 0; // Return an error code or success
}

extern "C" __declspec(dllexport) int PerformInference(const char* imagePath, char* outputData, int outputLength) {
    // Perform inference here
    return 0; // Return an error code or success
}

C# P/Invoke setup:

class OpenVinoInterop {
    [DllImport("YourModelDLL.dll", CharSet = CharSet.Ansi)]
    public static extern int LoadModel(string modelPath);

    [DllImport("YourModelDLL.dll", CharSet = CharSet.Ansi)]
    public static extern int PerformInference(string imagePath, StringBuilder outputData, int outputLength);
}

You would need to handle data marshaling between C# and C++ carefully, especially for image data and inference results.

This approach requires a good understanding of both C++ and C# interop features but can be very powerful. If you're not familiar with C++ or DLL creation, it might require some additional learning or collaboration with someone who has these skills.

Hope this helps you get started with using OpenVino in your C# environment! 🚀

Hi Paula, thanks for getting back to us.
Do you happen to have the Wrapper for this?
We can't create it in C++ here.

@arturcortellijunior hello!

Unfortunately, we don't have a pre-made C++ wrapper available for OpenVino that you can use directly. Creating such a wrapper requires specific expertise in both C++ and the OpenVino toolkit.

If creating a C++ DLL isn't feasible in your current setup, you might consider looking for external C++ development resources or consulting services that could assist in this task. Another alternative could be to explore if any community projects or third-party libraries offer a similar functionality that could be integrated into your project.

Sorry I couldn't provide a direct solution this time! If you have any more questions or need further assistance, feel free to ask. 🌟
