SslCertBinding.Net is a library for .NET and Windows and provides a simple API to add, remove or retrieve bindings between a https port and a SSL certificate.

This library can be considered as a programmatic alternative to Windows command line tools netsh http show|add|delete sslcert or httpcfg query|set|delete ssl.

SslCertBinding.Net is available as a NuGet package.

Install-Package SslCertBinding.Net

ICertificateBindingConfiguration config = new CertificateBindingConfiguration();
var ipPort = new IPEndPoint(IPAddress.Parse("0.0.0.0"), 443); 
var certificateThumbprint = "372680E4AEC4A57CAE698307347C65D3CE38AF60";
var appId = Guid.Parse("214124cd-d05b-4309-9af9-9caa44b2b74a");

// add a new binding record
config.Bind( new CertificateBinding(
	certificateThumbprint, StoreName.My, ipPort, appId)); //returns false

// get a binding record
var certificateBinding = config.Query(ipPort)[0];

// set an option and update the binding record
certificateBinding.Options.DoNotVerifyCertificateRevocation = true;
config.Bind(certificateBinding); //returns true

// remove the binding record
config.Delete(ipPort);

Cerificates configuration needs elevated permissions. Run Visual Studio as an Administrator before running unit tests.

Make sure that you have installed your certificate properly, certificate has a privaite key, your privaite key store is not broken, etc. Try binding your certificate with netsh CLI tool. If you get the same error it should not be a bug in SslCertBinding.Net.
