### [Abblix\.Oidc\.Server\.Model](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model 'Abblix\.Oidc\.Server\.Model')

## ConfigurationResponse Class

The OpenID Provider discovery document returned by the `/.well-known/openid-configuration` endpoint,
as defined by OpenID Connect Discovery 1\.0 §3 and OAuth 2\.0 Authorization Server Metadata \(RFC 8414\)\.
Its content lists the provider's endpoints, supported algorithms, response types, scopes, and feature flags
so that relying parties can configure themselves dynamically\.

```csharp
public record ConfigurationResponse : System.IEquatable<Abblix.Oidc.Server.Model.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/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.ConfigurationResponse 'Abblix\.Oidc\.Server\.Model\.ConfigurationResponse')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/system.iequatable-1 'System\.IEquatable\`1')

### Remarks
Decorated with [Abblix\.Utils\.Json\.JsonIgnoreNullsAttribute](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.json.jsonignorenullsattribute 'Abblix\.Utils\.Json\.JsonIgnoreNullsAttribute') so that all nullable optional properties are omitted
from the serialized JSON when `null`, rather than emitted as `"field": null`\.
RFC 8414 §2 requires that optional metadata fields be absent when not applicable — some OIDC client libraries
\(including `Microsoft.IdentityModel`\) reject a discovery document that contains `null` values for
fields they do not expect to be present\.
### Properties

## ConfigurationResponse\.AcrValuesSupported Property {#Abblix.Oidc.Server.Model.ConfigurationResponse.AcrValuesSupported}

matches what request\-time dispatch will accept\. Omitted from the emitted discovery
JSON when the list is empty \(no per\-type validators registered\) so the document
follows the OIDC discovery convention: absent = unsupported, not the empty array\.

## ConfigurationResponse\.SignedMetadata Property {#Abblix.Oidc.Server.Model.ConfigurationResponse.SignedMetadata}

RFC 8414 §2\.1: a JWS whose payload restates this entire metadata set, signed with the

keys at [JwksUri](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.ConfigurationResponse#Abblix.Oidc.Server.Model.ConfigurationResponse.JwksUri 'Abblix\.Oidc\.Server\.Model\.ConfigurationResponse\.JwksUri') may trust the configuration's origin beyond the TLS layer;
signed values take precedence over the corresponding plain\-JSON fields\. Emitted only
when `DiscoveryOptions.SignedMetadata` is enabled, and computed last so the signed
payload never contains this field itself\.

enforces the binding at its protected resources; omitted otherwise\.

```csharp
public System.Nullable<bool> TlsClientCertificateBoundAccessTokens { get; init; }
```
