Hello.
I'm tryng to delete some image from my app, but I can't find anything that help me to do it.
I'm using xamarin forms.

I would like to delete a picture after take it.

After taking the photo, with de following code:

var file = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions
{SaveToAlbum = false,
CustomPhotoSize = 50,
CompressionQuality = 50,
PhotoSize = new Plugin.Media.Abstractions.PhotoSize()
});

The images was saved inside the directory:

Android\data\MYAPP.Droid\files\Pictures

I would like to know if there someway to delete this images with the xamarin forms. And if will works in the iOS and WP to.
