Exception "Secure binary serialization is not supported on this platform"

Question

Hello, I am using Rebex.Net.Scp to connect to a device. This code works fine in .NET Framework 4.7.2, but fails in .NET 5.0

I get this exception:
"Secure binary serialization is not supported on this platform."
at System.Exception.add_SerializeObjectState(EventHandler`1 value)
at Rebex.SafeSerializer.PseudoExceptionStorage..ctor(SafeSerializer epk)
at Rebex.SafeSerializer..ctor(ISafeSerializable eoz)

at systemadministrator.Utils.NetworkConnection.CheckOnLineState(String caller, Boolean fromOnlineMonitor) in C:...\NetworkConnection.cs:line 582

System.Private.CoreLib

What can I do to make it work in .net 5.0 ?

Sincerely
Jon L.

This looks like you are using an old version of Rebex libaries that did not support .NET 5.0 yet.

To resolve the issue, please upgrade to 2020 R5.0 or later.

Yep! I was running 4.x. I upgraded to latest version. Now I don't get any exception anymore, thanx!
