## ConfigurationResponse Class

Framework\-agnostic OpenID Connect discovery metadata response\.
Contains provider capabilities, supported features, and cryptographic algorithms,
but excludes endpoint URLs which are framework\-specific\.

```csharp
public record ConfigurationResponse : System.IEquatable<Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.ConfigurationResponse>
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → ConfigurationResponse

Implements [System\.IEquatable&lt;](https://learn.microsoft.com/en-us/dotnet/api/system.iequatable-1 'System\.IEquatable\`1')[ConfigurationResponse](https://www.abblix.com/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.ConfigurationResponse 'Abblix\.Oidc\.Server\.Endpoints\.Configuration\.Interfaces\.ConfigurationResponse')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/system.iequatable-1 'System\.IEquatable\`1')

### Remarks
Each member's C\# nullability mirrors what OpenID Connect Discovery 1\.0 section 3 says about the corresponding
metadata field, so that the compiler asks of a handler exactly what the specification asks of a provider\.
The four fields that section marks REQUIRED are `required` here; everything else is nullable, because
RECOMMENDED and OPTIONAL fields are legitimately absent and `null` is how this type says "not stated"
\(the wire model omits nulls entirely\)\. Several of the optional ones carry a default that applies precisely
when the field is omitted, so omission is an answer rather than a gap: `grant_types_supported` defaults
to authorization code and implicit, `response_modes_supported` to query and fragment, and
`token_endpoint_auth_methods_supported` to client\_secret\_basic\.
Before this, all eleven were declared non\-nullable with a null\-forgiving initialiser, which swore they were
always present while nothing enforced it\. A custom [IConfigurationHandler](https://www.abblix.com/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.IConfigurationHandler 'Abblix\.Oidc\.Server\.Endpoints\.Configuration\.Interfaces\.IConfigurationHandler') that left one out
produced no error at all: the null travelled into the wire model, whose null\-omitting serialisation dropped
the field, so a discovery document could silently ship without a REQUIRED member and answer 200\.
