Alternative to SecurityBindingElement.CreateUserNameForCertificateBindingElement()

[dr-matthews]

Hi, I'm trying to migrate the following code from .NET Framework 4.8 to .NET 6.0/WCF 6.2. It appears that the SecurityBindingElement.CreateUserNameForCertificateBindingElement() method and its return type (SymmetricSecurityBindingElement) are not available in WCF. Is there another way I can achieve the same thing using functinality available in WCF 6.2? If not are there any 3rd party NuGet packages that may support it? Any help would be much appreciated

private static BindingElement CreateSecurityBindingElement()
{
	var bootstrapSecurity = SecurityBindingElement.CreateUserNameForCertificateBindingElement();
	
	var security = SecurityBindingElement.CreateSecureConversationBindingElement(bootstrapSecurity);
	security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Default;
	security.IncludeTimestamp = true;
	security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

	return security;
}
