### Redirecting Activation to Recommended Instance

Source: https://learn.microsoft.com/en-us/uwp/api/windows.applicationmodel.appinstance.recommendedinstance

This example demonstrates checking if a recommended instance is available and suitable, and then redirecting activation to it. If no recommendation is made, the app handles the redirection logic itself.

```APIDOC
## Examples

This example checks whether the shell recommends an instance, by using the app-defined _SelectedKeyIncludesMyKey_ method. If so, it checks whether the instance is suitable, and redirects to a suitable instance. If the shell does not have preference, the app can look for an existing app instance to redirect to or attempt to register itself as the target.

```csharp
AppInstance RecommendedInstance = AppInstance.RecommendedInstance;
if ((RecommendedInstance != null) && SelectedKeyIncludesMyKey(RecommendedInstance.Key))
{
    RecommendedInstance.RedirectActivationTo();
}
else
{
    // Look for existing instance or attempt to register itself as target.
}
```
