[keycloak-user] .NET Core OIDC auth

I'm trying to integrate an ASP .NET Core client web app with Keycloak using the .NET Core native OIDC Support. For this I'm using a sample project available in the IdentityServer Github repo [1]. IdentityServer is an OIDC Auth Server/Framework implementation for .NET platform. I forked that sample repo and changed the configuration to use the Keycloak OIDC endpoints. The code snippet changed to use keycloak endpoint is this one <https://github.com/rafaeltuelho/IdentityServer4.Samples/blob/dev/MVC%20an...;. I was able to run this code on my RHEL 7 box using .NET Core for Linux [2]. In the KC side I just created a new realm and a client (see the dotnetcore.json realm config attached). The web app starts and the secured pages/resources redirects the user to the Keycloak endpoint, but after the user authenticates and KC responds the request the following error occurs on .NET client side: "OpenIdConnectProtocolInvalidCHashException: IDX10307: *The 'c_hash' claim was not found in the id_token*, but a 'code' was in the OpenIdConnectMessage, id_token: '{"alg":"RS256","typ":"JWT"}.{"jti":"cae47265-327e-4961-aeb2-6615713cc6f8","exp":1469508079,"nbf":0,"iat":1469507779,"iss":" http://localhost:8080/auth/realms/dotnetdemo","aud":"... NET","preferred_username":"dotnetuser","given_name":"dot","family_name":"NET","email":" donetuser(a)localhost.com&quot;}&#39;&quot; Searching for this message "*The 'c_hash' claim was not found in the id_token*" I found the issue *KEYCLOAK-3286* [3]. Does this error have something to do with the *KEYCLOAK-3286?* Does some one tried to integrate a .NET app with Keycloak using OIDC protocol?
