GroupdocsViewerController exist in both 'Groupdocs.Web.Annotation.dll' and 'Groupdocs.Web.UI.Signature.dll'



I am trying to use Annotaion and Signature library together. but as soon as i add Signature library, i am getting error of The type ‘Groupdocs.Web.UI.Controllers.GroupdocsViewerController’ exists in both ‘Groupdocs.Web.Annotation.dll’ and ‘Groupdocs.Web.UI.Signature.dll’. in my ‘UnityControllerFactory.cs’ file.

I tried to solve this error by providing alias to both the dll, but it didnt solve the issue. Is there any way through which i can use these 2 library together???

I am using groupdocs-annotation-dotnet.2.1.1 and groupdocs-signature-dotnet.1.11.0



I’m sorry to hear that you have such issue. I was able to reproduce it and created a ticket for our Product team.

When the fix will be available - I will notify you here.

Best regards.



I hope your team has found success to solve my above issue, as its kind of urgent for me.
Waiting for a positive response.



Sorry for the delay. We still work on the investigation of the issue. Please be patient and we will come back to you shortly with more info.

Sorry for the inconvenience.



Thank you for your patience. Unfortunately the issue is much more complicated and complex and will require a lot of modifications in both libraries. But in the same time I want to notify you that the next generation Annotation library will be released shortly and the next generation Signature will be released in the next month - they will not have such issue because these libraries are totally rebuilded and UI less. Since that I want to check if you can wait for these releases and use the new libraries.

Also such approach will be better for you because you will not need to migrate on the new libraries after release and rebuild your project.

Sorry for the inconvenience.
