Signout with ADFS3 with SAML

I have implemented SSO using ADFS3. I have a logout button for sign out and it’s working fine with my ws-federation passive endpoints. On logout I redirect user to logout.aspx page and there I have written code on page load as

WSFederationAuthenticationModule authModule = FederatedAuthentication.WSFederationAuthenticationModule;

SignOutRequestMessage signOutRequestMessage = new SignOutRequestMessage(new Uri(authModule.Issuer), authModule.Realm);
            String queryString = signOutRequestMessage.WriteQueryString();
            Response.Redirect(queryString);

One of the applications uses SAML so I have created a SAML assertion consumer endpoint. So when I open this application and hit logout it throws an error and when I view the event log for ADFS, I see

Encountered error during federation passive request.
