## ServiceCollectionExtensions Class

Extension methods for adding OpenID Connect \(OIDC\) server services to the [Microsoft\.Extensions\.DependencyInjection\.IServiceCollection](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.iservicecollection 'Microsoft\.Extensions\.DependencyInjection\.IServiceCollection')\.
These methods simplify the integration of OIDC server capabilities into an ASP\.NET Core application,
allowing for the configuration of OIDC options and services necessary for authentication and authorization\.

```csharp
public static class ServiceCollectionExtensions
```

### Remarks
The request pipeline must call `app.UseCors()` after `app.UseRouting()`\. The protocol
controllers carry CORS metadata, because browser\-based clients read the discovery document, the
key set and the token endpoint cross\-origin \- and ASP\.NET Core routing refuses to serve any
endpoint whose CORS metadata no middleware honours, so without that call every protocol endpoint
answers 500\. The policy itself is registered here; only the middleware call belongs to the host,
since the framework accepts the middleware only when it runs after routing has selected an
endpoint \- a place no library can insert it from\.

## ServiceCollectionExtensions\.AppPolicy\(this CorsOptions, string, CorsSettings\) Method {#Abblix.Oidc.Server.Mvc.ServiceCollectionExtensions.AppPolicy(thisMicrosoft.AspNetCore.Cors.Infrastructure.CorsOptions,string,Abblix.Oidc.Server.Mvc.Configuration.CorsSettings)}

This method enables the customization of CORS policies for OIDC endpoints, allowing for the specification
of allowed origins, methods, and headers, as well as whether credentials are supported\.

```csharp
public static void AppPolicy(this Microsoft.AspNetCore.Cors.Infrastructure.CorsOptions options, string policyName, Abblix.Oidc.Server.Mvc.Configuration.CorsSettings settings);
```
#### Parameters
