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

## ServiceCollectionExtensions Class

Extension methods for integrating OpenID Connect \(OIDC\) core services into an application's service collection\.

```csharp
public static class ServiceCollectionExtensions
```

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

### Remarks
These methods facilitate the setup of essential components for implementing OIDC authentication and
authorization flows, such as token issuance, client authentication, and session management\.
By calling these extension methods, developers can configure and customize the OIDC server according
to their application's security requirements and user management policies\.
### Methods

## ServiceCollectionExtensions\.AddEndpoints\(this IServiceCollection\) Method {#Abblix.Oidc.Server.ServiceCollectionExtensions.AddEndpoints(thisMicrosoft.Extensions.DependencyInjection.IServiceCollection)}

Configures the service collection with the always\-on OAuth 2\.0 and OpenID Connect endpoints — the set
mounted unconditionally regardless of [EnabledEndpoints](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.Configuration.OidcOptions#Abblix.Oidc.Server.Common.Configuration.OidcOptions.EnabledEndpoints 'Abblix\.Oidc\.Server\.Common\.Configuration\.OidcOptions\.EnabledEndpoints'): discovery, authorization,
PAR, token, UserInfo and end session\.

```csharp
public static Microsoft.Extensions.DependencyInjection.IServiceCollection AddEndpoints(this Microsoft.Extensions.DependencyInjection.IServiceCollection services);
```
#### Parameters

###### `services` [Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection') {#Abblix.Oidc.Server.ServiceCollectionExtensions.AddEndpoints(thisMicrosoft.Extensions.DependencyInjection.IServiceCollection).services}

The [Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection') to configure with necessary endpoints\.

#### Returns
[Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection')  
The configured [Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection'), enabling further service registration chaining\.

### Remarks
By calling this method, the application integrates support for:

\- The Configuration \(discovery\) Endpoint for publishing provider metadata\.
\- The Authorization Endpoint for initiating user authentication and consent\.
\- Pushed Authorization Request \(PAR\) Endpoint for pre\-registering authorization requests\.
\- Token Endpoint for issuing tokens following successful authentication\.
\- User Info Endpoint for accessing authenticated user information\.
\- End Session Endpoint for managing user logout processes\.

The niche or security\-sensitive endpoints — Revocation, Introspection, CIBA, Check Session and Dynamic
Client Registration — are not wired here\. Each is opt\-in through its dedicated `AddX()` feature method
\(`AddRevocation`, `AddIntrospection`, `AddBackChannelAuthentication`, `AddCheckSession`,
`AddDynamicClientRegistration`\), which registers the endpoint services and re\-enables its flag in
[EnabledEndpoints](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.Configuration.OidcOptions#Abblix.Oidc.Server.Common.Configuration.OidcOptions.EnabledEndpoints 'Abblix\.Oidc\.Server\.Common\.Configuration\.OidcOptions\.EnabledEndpoints') \(defaulting to [Base](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.Configuration.OidcEndpoints#Abblix.Oidc.Server.Common.Configuration.OidcEndpoints.Base 'Abblix\.Oidc\.Server\.Common\.Configuration\.OidcEndpoints\.Base')\)\.

## ServiceCollectionExtensions\.AddFeatures\(this IServiceCollection\) Method {#Abblix.Oidc.Server.ServiceCollectionExtensions.AddFeatures(thisMicrosoft.Extensions.DependencyInjection.IServiceCollection)}

Registers a comprehensive set of services related to client authentication, information management,
issuer identification, token services, JWT handling, session management, random value generation
and logout notifications\.

```csharp
public static Microsoft.Extensions.DependencyInjection.IServiceCollection AddFeatures(this Microsoft.Extensions.DependencyInjection.IServiceCollection services);
```
#### Parameters

###### `services` [Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection') {#Abblix.Oidc.Server.ServiceCollectionExtensions.AddFeatures(thisMicrosoft.Extensions.DependencyInjection.IServiceCollection).services}

#### Returns
[Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection')  
The configured [Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection'), allowing for further chaining of service registrations\.

### Remarks
This method serves as a convenience wrapper that aggregates the registration of various foundational services
necessary for the application's security and functionality\.

It includes:
\- Client authentication mechanisms\.
\- Client information management\.
\- Issuer identification\.
\- Token generation, validation and management services\.
\- JSON Web Token \(JWT\) support\.
\- Session management capabilities\.
\- Random value generators for security tokens and identifiers\.
\- Logout notification mechanisms\.

By invoking this method, an application ensures that all critical security and operational features
are configured and ready for use\.

## ServiceCollectionExtensions\.AddOidcCore\(this IServiceCollection, Action\<OidcOptions,IServiceProvider\>\) Method {#Abblix.Oidc.Server.ServiceCollectionExtensions.AddOidcCore(thisMicrosoft.Extensions.DependencyInjection.IServiceCollection,System.Action_Abblix.Oidc.Server.Common.Configuration.OidcOptions,System.IServiceProvider_)}

Adds OIDC server core services to the service collection with additional access to the service provider
for more complex configuration scenarios\.
