The LEADTOOLS .NET Core SDK has support for PDF417 barcodes (https://www.leadtools.com/sdk/barcode/2d-pdf417). The toolkit can both read and write the barcode and save the result in a wide range of supported image and document formats. (Disclaimer: I am an employee of this toolkit’s vendor).

The code to write PDF417 barcodes would look something like the following:
RasterImage rasterImage = null;
string filepath = "Path to image to write the barcode on"; // File name - the image file to be read from or written on
string value = "Insert Data Here"; // Barcode data - the data string to be written on the image
LeadRect location = new LeadRect(left,top,width,height); // Barcode location - the location of the written barcode

using (var rasterCodecs = new RasterCodecs())
{
   rasterCodecs.Options.RasterizeDocument.Load.Resolution = 300;
   BarcodeData data = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.PDF417);
   data.Value = value;
   data.Bounds = location;
   rasterImage = rasterCodecs.Load(filepath);
   barcodeEngine.Writer.WriteBarcode(rasterImage, data, null);
   rasterCodecs.Save(rasterImage, filepath , RasterImageFormat.CcittGroup4, 1);
}
