Insert a new contact intent

Question

For one of my apps, I need the user to select one of his existing contacts or to create a new one. Picking one is clearly easy to do with the following code:

Answer 1

In Xamarin.forms and Xamarin.Android c#.

Android.Content.Intent intent = new  
Android.Content.Intent(Android.Content.Intent.ActionInsert);
intent.SetType(Android.Provider.ContactsContract.Contacts.ContentType);
intent.PutExtra(Android.Provider.ContactsContract.Intents.ExtraForceCreate, 
true);
StartActivity(intent);
