#### Creating a New Provider
To integrate a custom provider, such as InMemoryProvider, you’ll need to create a factory that builds and configures the provider. This section demonstrates how to set up InMemoryProvider as a new provider with custom configuration options.

**Configuring InMemoryProvider as a New Provider**
<br />Begin by creating a custom factory class, `InMemoryProviderFactory`, that implements `IFeatureProviderFactory`. This factory will initialize your provider with any necessary configurations.
```csharp
public class InMemoryProviderFactory : IFeatureProviderFactory
{
internal IDictionary<string, Flag>? Flags { get; set; }

public FeatureProvider Create() => new InMemoryProvider(Flags);
}
```
**Adding an Extension Method to OpenFeatureBuilder**
<br />To streamline the configuration process, add an extension method, `AddInMemoryProvider`, to `OpenFeatureBuilder`. This allows you to set up the provider with either a domain-scoped or a default configuration.
### Registering a Custom Provider
You can register a custom provider, such as `InMemoryProvider`, with OpenFeature using the `AddProvider` method. This approach allows you to dynamically resolve services or configurations during registration.

```csharp
public static partial class FeatureBuilderExtensions
{
public static OpenFeatureBuilder AddInMemoryProvider(this OpenFeatureBuilder builder, Action<IDictionary<string, Flag>>? configure = null)
=> builder.AddProvider<InMemoryProviderFactory>(factory => ConfigureFlags(factory, configure));
services.AddOpenFeature()
.AddProvider(provider =>
{
// Resolve services or configurations as needed
var configuration = provider.GetRequiredService<IConfiguration>();
var flags = new Dictionary<string, Flag>
{
{ "feature-key", new Flag<bool>(configuration.GetValue<bool>("FeatureFlags:Key")) }
};

// Register a custom provider, such as InMemoryProvider
return new InMemoryProvider(flags);
});
```

public static OpenFeatureBuilder AddInMemoryProvider(this OpenFeatureBuilder builder, string domain, Action<IDictionary<string, Flag>>? configure = null)
=> builder.AddProvider<InMemoryProviderFactory>(domain, factory => ConfigureFlags(factory, configure));
#### Adding a Domain-Scoped Provider

private static void ConfigureFlags(InMemoryProviderFactory factory, Action<IDictionary<string, Flag>>? configure)
{
if (configure == null)
return;
You can also register a domain-scoped custom provider, enabling configurations specific to each domain:

var flag = new Dictionary<string, Flag>();
configure.Invoke(flag);
factory.Flags = flag;
}
}
```csharp
services.AddOpenFeature()
.AddProvider("my-domain", (provider, domain) =>
{
// Resolve services or configurations as needed for the domain
var flags = new Dictionary<string, Flag>
{
{ $"{domain}-feature-key", new Flag<bool>(true) }
};

// Register a domain-scoped custom provider such as InMemoryProvider
return new InMemoryProvider(flags);
});
```
