options.UseAspNetCore(), only that doesn't seem to be recognized as a valid method. Neither does
.AddValidation()and its children. Did something change I'm not picking up?
OpenIddict.Validation.AspNetCore, that are referenced by the
OpenIddict.Owin, which works exactly like
return SignIn(principal, OpenIddictServerAspNetCoreDefaults.AuthenticationScheme);is returning the sign-in page html instead of a token or redirect to the token endpoint?
