SslStream.AuthenticateAsServer throws The server mode SSL must use a certificate with the associated private key

Question

Cheers,

I have a *.crt with a CERTIFICATE section and a PRIVATE KEY section I load this certificate with

X509Certificate2 serverCertificate = X509Certificate2.CreateFromCertFile("Data\\certificate.crt");

Now I want to start a secure TcpListener, but get at

SslStream sslStream = new SslStream(client.GetStream(), false);
sslStream.AuthenticateAsServer(serverCertificate, clientCertificateRequired: true, checkCertificateRevocation: true);

the error "The server mode SSL must use a certificate with the associated private key"...

Whats the problem?

This answer is for C# .NET

For HTTPS calls, the example is provided on MSDN using TCP Listner and TCP Client.

When doing sslStream.AuthenticateAsServer(serverCertificate, ..) you should load a PFX file along with password, instead of CER file, then it will not require registration on client machine. if works please tell me i have problems after this :P
