Embed SSL certificate in self-service .NET server application (WCF / SignalR): How?

We have a standalone web socket server built in .NET 4.51 and SignalR.

Works great.

We can make SSL a penalty by referencing the certificate in the Windows machine store.

Fine.

Our project requires our exe (web socket server built in SignalR) to be portable and able to serve SSL server globally without interacting with the OS certificate store.

Possible?

How can we approach this?

(Yes, we understand that the private key, etc. will be embedded in the exe and could be stolen.)
