PDF Viewer could not load files.

[Peng Xie]

I have problem by using .Net Core with pdfViewer. In the cshtml.cs file after I imported necessary library, errors generated.

Severity Code Description Project Path File Line Suppression State

Error CA2000 Call System.IDisposable.Dispose on object created by 'new PdfRenderer()' before all references to it are out of scope. 

I download demo pdfViewer file for testing, it could not load file either.

Hi,

I am working with .net core with razor page. Do you have sample code for that?

BTW, the one I found on here

Does not work for me.

Hi Peng, 

From the 2019 Volume 2 beta release new annotation features were included in the PDF Viewer but the KB content is not updated, so the error is thrown with the provided code snippet and the sample. Now, we have updated the KB content and the sample. Please find the updated kb link as below.
