As per your recommendation, I have opened there the issue instead of https://forum.aspose.com. I have downloaded cloud code in .NET but that is not executed in 3.5 frame work. Please tell me which framework is comfort for this sample .net code.
Thank you for contacting Aspose Support.
Would you please confirm you have downloaded Aspose.OCR Cloud SDK for .NET from here?
The SDK should compile fine with .NET framework 2.0 or higher. We would appreciate if could share the exact error you are getting. We would fix it at the earliest.
