## ResponseModeValidator Class

Verifies that an explicit `response_mode` is compatible with the OAuth 2\.0 flow
derived from `response_type` \(OAuth 2\.0 Multiple Response Types §2\.1, OAuth 2\.0
Form Post Response Mode\)\. For the authorization\-code flow any of `query`,
`fragment`, `form_post` is allowed; flows that issue tokens at the
authorization endpoint \(implicit, hybrid\) refuse `query` because credentials
must not appear in the URL query string\.

```csharp
public class ResponseModeValidator : Abblix.Oidc.Server.Endpoints.Authorization.Validation.SyncAuthorizationContextValidatorBase
```
