How to get new or refresh access token with wsfed for .net core?

Question

I am using wsfederation(with pingfederate as IDP) for authenticating. This is working fine for getting access token first time, but when the token got expired, I need to get a new token or refresh token. In .NET framework 4.7.2 it is working fine as we uses WS2007FederationHttpBinding and WSTrustChannelFactory to get new token. But in .NET CORE I did not get any way to get the access token forcefully.

Do anyone have any idea on how do I get the new token by calling a API from my controller?

I'm stuck on the same problem. I have code for requesting a token from STS in .NET Framework also using WSTrustChannelFactory but I've been unable to find the equivalent in .NET Standard. – Spindlelegs
