1. Syncfusion.Compression.Base.dll
2. Syncfusion.Pdf.Base.dll
3. Syncfusion.OCRProcessor.Base.dll

The below screenshot shows the Tesseract binaries and Tesseract data added as separate files inside App_Data folder of the project.

Once the files are added, rebuild the project, then the added files can be found inside the “bin” folder of the project.

Step 3:
