    We’re using the WebForms C1.C1Report.4.dll (Version 4.6.20131.54624, 08/27/2021) in our .Net Framework 4.5 reporting projects and have found that the larger PDF’s no longer render and error out after we recently upgraded our site from Server 2012 to Server 2022. I was unable to find much on compatibility here on the site, and wondering if anyone else has experienced this, or may have a suggestion? Thanks in advance!

    Hi Manish,

    The project is too big. It is 26.7Mb with the Telerik DLLs. I will pull the larger files out of the bin directory and send it. The page in the project that calls the C1.C!Report is\WRS_Zip\Reports\WRSViewer.aspx. I tried the latest C1.C!Report4.dll from 07/2022, and the report still errors on PDF files. We rolled the server back from 2022 to 2012 and all is working again. I also attached the error we are seeing. Thanks!

    Hi Richard,

    Thank you for sharing the sample but this is not executable and we are unable to find the report.

    Could you please share the executable project or share the C1Report and the corresponding DataBase?
