We are doing a Favro issue tracking extension for Plastic. The extension is working on Windows properly and almost working on Linux. I have 2 questions: 1. We need to recompile the extension for every version of Plastic because we're suffering .NET DLL Hell problem. I've tried using the bindingRedirect mecanism with the issuetrackerinterface.dll to reduce the problem at least enabling backward compatibility but without any success. Do you know any way to avoid the need to recompile the dll plugin for every Plastic version? 2. I'm having one issue in linux when accessing the Favro API with HttpWebRequest.GetResponse() method if the URL is https. It seems the mono included in the Plastic installation do not have complete TLS support. If I do the same request using a typical linux mono instalation, all is working properly. This is the exception thrown: 2020-08-14 01:18:12,596 goldenbox ERROR favroextension - Unexpected error while retrieving assigned cards System.Net.WebException: Error: SecureChannelFailure (The authentication or decryption has failed.) ---> System.IO.IOException: The authentication or decryption has failed. ---> System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: The authentication or decryption has failed. at Mono.Security.Protocol.Tls.RecordProtocol.EndReceiveRecord (System.IAsyncResult asyncResult) [0x00040] in <9c4d6f9060314ca4a265631d657910a8>:0 at Mono.Security.Protocol.Tls.SslClientStream.SafeEndReceiveRecord (System.IAsyncResult ar, System.Boolean ignoreEmpty) [0x00000] in <9c4d6f9060314ca4a265631d657910a8>:0 at Mono.Security.Protocol.Tls.SslClientStream.NegotiateAsyncWorker (System.IAsyncResult result) [0x00071] in <9c4d6f9060314ca4a265631d657910a8>:0 --- End of inner exception stack trace --- at Mono.Security.Protocol.Tls.SslClientStream.EndNegotiateHandshake (System.IAsyncResult result) [0x0003b] in <9c4d6f9060314ca4a265631d657910a8>:0 at Mono.Security.Protocol.Tls.SslStreamBase.AsyncHandshakeCallback (System.IAsyncResult asyncResult) [0x0000c] in <9c4d6f9060314ca4a265631d657910a8>:0 --- End of inner exception stack trace --- at Mono.Security.Protocol.Tls.SslStreamBase.EndRead (System.IAsyncResult asyncResult) [0x00057] in <9c4d6f9060314ca4a265631d657910a8>:0 at Mono.Net.Security.Private.LegacySslStream.EndAuthenticateAsClient (System.IAsyncResult asyncResult) [0x00011] in <9c4d6f9060314ca4a265631d657910a8>:0 at Mono.Net.Security.Private.LegacySslStream.AuthenticateAsClient (System.String targetHost, System.Security.Cryptography.X509Certificates.X509CertificateCollection clientCertificates, System.Security.Authentication.SslProtocols enabledSslProtocols, System.Boolean checkCertificateRevocation) [0x0000e] in <9c4d6f9060314ca4a265631d657910a8>:0 at Mono.Net.Security.MonoTlsStream.CreateStream (System.Byte[] buffer) [0x00044] in <bd46d4d4f7964dfa9beea098499ab597>:0 --- End of inner exception stack trace --- at System.Net.HttpWebRequest.EndGetResponse (System.IAsyncResult asyncResult) [0x00064] in <bd46d4d4f7964dfa9beea098499ab597>:0 at System.Net.HttpWebRequest.GetResponse () [0x0000e] in <bd46d4d4f7964dfa9beea098499ab597>:0 at FavroPlasticExtension.Favro.API.Connection.ParseWebResponse (System.Net.HttpWebRequest request) [0x00008] in <7a01fcc46c0e49f295ff341e41727ae6>:0 I've found a way to select the TLS provider setting the environment variable MONO_TLS_PROVIDER to "newtls" and then launching Plastic.

reproduce this exception directly from bash is launching this command: /opt/plasticscm5/certtools/certmgr -ssl https://favro.com And if you use the default mono certmgr works ok: certmgr -ssl

Thank you so much.
