# IFeatureManagerSnapshot

The **IFeatureManagerSnapshot** service can be injected anywhere else more suitable helper methods aren't available. 

```csharp
private readonly IFeatureManagerSnapshot _featureManager;

public UsersController(IFeatureManagerSnapshot featureManager)
{
    _featureManager = featureManager;
}

[Route("")]
public async Task<IActionResult> Index()
{
    var feature1Enabled = await _featureManager.IsEnabledAsync(FeatureFlags.Feature1);

    return View(feature1Enabled ? "Feature1Index" : "Index");
}
```

{% hint style="info" %}
**IFeatureManagerSnapshot** persists the values of the flags returned throughout the current request, and is recommended to be used over calling **IFeatureManager** directly, so you don't end up with different values for the a flag on the same request.&#x20;
{% endhint %}

**IFeatureManager** is used by the **FeatureMangerSnapshot** to retrieve the computed value of each flag on each call, and it can be used the same way IFeatureManagerSnapshot is used.
