There are two main methods, PerformInAppRateAsync and PerformRatingOnStoreAsync.

⚠️ Warning - You should be careful about how and when you ask users to rate your app, there may be penalties from stores. As for advice, I recommend using a counter on the app start and storage that count, then when the counter reaches a certain number, display a dialog asking the users if they want to rate the app, if they decline the offer, reset the counter to ask them later, also leave the option to do it themselves.
public partial class MainPage : ContentPage
{
private const string androidPackageName = "com.facebook.katana";
private const string iOSApplicationId = "id284882215";
private const string uwpProductId = "9wzdncrf0083";
public MainPage()
{
InitializeComponent();
if (!Preferences.Get("application_rated", false))
Task.Run(() => CheckAppCountAndRate());
}
private async Task CheckAppCountAndRate()
{
if (Preferences.Get("application_counter", 0) >= 5)
{
if (!await DisplayAlert("Rate this App!", "Are you enjoying the app so far? Would you like to leave a review in the store?", "Yes", "No"))
{
Preferences.Set("application_counter", 0);
return;
}
await RateApplicationInApp();
}
}
private Task RateApplicationInApp()
{
if (CrossAppRating.IsSupported)
{
Device.BeginInvokeOnMainThread(async () =>
{
// This method will simulate Facebook™ app to in-app rating as example.
await CrossAppRating.Current.PerformInAppRateAsync();
});
Preferences.Set("application_rated", true);
}
return Task.CompletedTask;
}
private Task RateApplicationOnStore()
{
if (CrossAppRating.IsSupported)
{
Device.BeginInvokeOnMainThread(async () =>
{
// This method use Facebook™'s store apps as example.
await CrossAppRating.Current.PerformRatingOnStoreAsync(packageName: androidPackageName, applicationId: iOSApplicationId, productId: uwpProductId);
});
Preferences.Set("application_rated", true);
}
return Task.CompletedTask;
}
private void InAppRating_Clicked(object sender, EventArgs e)
{
if (!Preferences.Get("application_rated", false))
Task.Run(() => RateApplicationInApp());
}
private void AppRateOnStore_Clicked(object sender, EventArgs e)
{
if (!Preferences.Get("application_rated", false))
Task.Run(() => RateApplicationOnStore());
}
