How to use the oAuth refresh token to acquire a new token?

[wmmihaa]

Is there anyone who could tell me how to use the refresh token to get a new token. I've read through the AAD documentation on the subject, But all I get is: "AADSTS50012: Invalid client secret is provided."

I've had success with this:

using Microsoft.IdentityModel.Clients.ActiveDirectory;

public void Refresh(string authorityUri, string ClientID, string ClientSecret, string RefreshToken)
{
	TokenCache TC = new TokenCache();
	AuthenticationContext AC = new AuthenticationContext(authorityUri, TC);
	ClientCredential cc = new ClientCredential(ClientID, ClientSecret);
	AuthenticationResult AR = AC.AcquireTokenByRefreshToken(RefreshToken, cc));
}
