Does Abotx support Net 5.x? I ask because I'm trying to get the demo code to work (shown under 'Using AbotX at https://github.com/sjdirect/abotx) and it fails with the following error: Unhandled exception. System.Security.Cryptography.CryptographicException: ASN1 corrupted data.

TEST ENVIRONMENT

Visual Studio 2019 for Mac

net5.0

I created a new project, used nuget to install AbotX, then inserted the demo code and tried to run. Got the above error.

Note that when I repeated these steps using Visual Studio 2019 on Windows10 and using the NETFramework 4.7.1, it runs just fine.

I figured that if AbotX supports Net Standard 2.0, it would support net5.0.

Thanks,

Rob Jones

Thought it might be more helpful to post the complete exception message that I get:

More info. I discovered that this works with netcore3.1. Also, here is the complete error context when running under net5.0:
