# Custom Context

In console applications there is no ambient context such as `HttpContext` that feature filters can acquire and utilize to check if a feature should be on or off. In this case, applications need to provide an object representing a context into the feature management system for use by feature filters. This is done by using `IFeatureManager.IsEnabledAsync<TContext>(string featureName, TContext appContext)`. The appContext object that is provided to the feature manager can be used by feature filters to evaluate the state of a feature.

```csharp
MyAppContext context = new MyAppContext
{
    AccountId = current.Id;
}

if (await featureManager.IsEnabledAsync(feature, context))
{
    ...
}
```
