Looping custom claims on login - Asp.net core - asp.net-core

Question

Our ASP.NET MVC application connects to IdentityServer 3 with the following config and able to access all the custom claims
app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
Authority = IdentityServerUrl,
ClientId = IdentityClientId,
ResponseType = "id_token token",
Scope = "openid profile myScope",
SignInAsAuthenticationType = "Cookies",
Notifications = new OpenIdConnectAuthenticationNotifications
{
SecurityTokenValidated = async n =>
{
var newIdentity = new ClaimsIdentity(
n.AuthenticationTicket.Identity.AuthenticationType,
"name",
"myrole");
var userInfoClient = new UserInfoClient(
new Uri(n.Options.Authority + "/connect/userinfo"),
n.ProtocolMessage.AccessToken);
var userInfo = await userInfoClient.GetAsync();
userInfo.Claims.ToList().ForEach(ui => newIdentity.AddClaim(new Claim(ui.Item1, ui.Item2)));
var sid = n.AuthenticationTicket.Identity.Claims.FirstOrDefault(x => x.Type == "sid");
if (sid != null)
{
newIdentity.AddClaim(new Claim("sid", sid.Value));
}
n.AuthenticationTicket = new AuthenticationTicket(
newIdentity,
n.AuthenticationTicket.Properties);
}
}
});
Now we want to upgrade and connect to IdentityServer 3 with .net core
We tried below code but I am not getting the sure how to loop through all the custom claims
.AddOpenIdConnect("oidc", options =>
{
options.Authority = IdentityClientUrl;
options.ClientId = IdentityClientId;
options.ResponseType = OpenIdConnectResponseType.IdTokenToken;
options.Scope.Clear();
options.Scope.Add("profile");
options.Scope.Add("openid");
options.Scope.Add("email");
options.Scope.Add("myScope");
options.GetClaimsFromUserInfoEndpoint = true;
options.TokenValidationParameters = new TokenValidationParameters
{
NameClaimType = "name",
RoleClaimType = "myrole"
};
options.SaveTokens = true;
options.ClaimActions.MapUniqueJsonKey("myrole", "myrole", "string");
});
In the existing approach, i am able to get all the claims from userInfo, so I can loop and add everything.
In the asp.net core - however I can map them using ClaimActions, eachone at a time. Is there any way I can loop throug all of them and add all of them - say I don't know the claimType!
Any help please?

You can try this to map all the claims using the MapAllExcept method, like:
options.ClaimActions.MapAllExcept("iss", "nbf", "exp", "aud", "nonce");
