using a timestampserver hangs in .net 4.8

[Frederico Regateiro]

Hello

I'm using Syncfusion.Pdf.Net.Core version 23.1.43 to sign a pdf file.

The project is using <TargetFrameworks>net48;net7.0</TargetFrameworks>

If i set a timestampserver and set the EmableLtv=true, on .net 7.0 it works fine, but if change to .net 4.8 the process hangs and do nothing.

The code i'm working on github

Thanks,

Frederico

After closely examining the reported hanging problem and carefully reviewing the provided information, the cause due to response call from the HTTP web request going into a waiting state by the HttpWebResponse.GetResponseStream function when using the .Net Framework application along with either the Syncfusion.Pdf.NET or Syncfusion.Pdf.NetCore package. We utilize the HTTP web request functionality to verify and include revocation information and timestamp data in the PDF document. To ensure that this process works smoothly across all environments, we've made some functional adjustments to how HTTP web requests are handled.

To avoid this kind problem in the signing and signature validation process, we recommend installing the recommended NuGet packages for recommend application as suggested.
