While trying to use the trial Groupdocs Viewer 17.5.0 in our application , we have added the Groupdocs.Viewer.dll and then added these below lines of code as mentioned in the guide https://docs.groupdocs.com/display/viewernet/How+to+Use+GroupDocs.Viewer+for+.NET+MVC4 to add global.ascx file after area registration.

Hi Kushal,


Thanks for taking interest in GroupDocs.Viewer for .NET.

You are facing the issues because of using DLL of next generation GroupDocs.Viewer for .NET API with the source code of a legacy version of the application which is obsolete now.

Before moving further, please note that the next generation GroupDocs.Viewer for .NET (starting from v3.0.0) is a back-end API that renders the supported document formats into HTML pages or images as per user’s choice. You will have to develop your own front end application in order to view the rendered HTML pages or images.

We have also provided some open source document viewer applications to demonstrate the working of the next generation API. You can download these open source applications from here. To evaluate the back-end features of the API, please download the example project that contains source code of all the features in the form of functions.

We recommend you to please have a look at the documentation of the API and in case you would have any questions or queries, please do let us know.

Warm Regards
