Hi @MahalingPatil ,

Please mention the specific package name.

Thanks & Regards,
Jayesh Thorat.


I install a package from available packages named “IronBarcode - The C# Barcode & QR Library”

But there is no new activities are added in UI Path.

Please give suggestions. @ClaytonM @palindrome @vvaidya @MahalingPatil @vangara0209

You have just included nuget library . It is not a custom activity … you ll need to write the c# code and use the library to get the bar code…

Can you please tell me the package name…

@Jayesh_678 you need to write the c# code and use the library to get the bar code.
