Facing issue with attaching SSL certificate with .Net Framework 4.8

Hello everyone,

We have a requirement to attach the SSL certificate while consuming SOAP services. We are getting an error as "Could not establish secure channel for SSL/TLS with authority 'url.com:portnumber'/". Inner Exception WebException: The request was aborted: Could not create SSL/TLS secure channel when we try to attach it using .net framework 4.8, However, we can make the connection with the same URL and same certificate using .Net core 6.0.

After further research, we found that the certificate is attached with .NetFramework 4.8 but it's not reaching the SOAP service. Is there any such limitation with .Net framework 4.8 or is there any different way of attaching the SSL certificate using .net framework 4.8? I am using the sample code below to attach the SSL cert,

System. Net. ServicePointManager.SecurityProtocol = System.Net. SecurityProtocolType. Tls12;

InqSvc_v1_0Client serviceClient = new InqSvc_v1_0Client("SOAPURL");

serviceClient.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName. Root, X509FindType.FindBySerialNumber, "SSL_CertSerialNumber");

res.InqRs = serviceClient.Inq(ss);

Any help will be greatly appreciated!
