+The library allows to use an implementation of Microsoft.Extensions.Caching.Distributed.IDistributedCache for caching map tile bitmaps.
 
 Map Control comes with three such implementations:
-* ImageFileCache, an IDistributedCache implementation that stores each cached map tile as a single image file,
+* ImageFileCache, an implementation that stores each cached map tile as a single image file,
 in the original file format delivered by the map provider (typically PNG or JPG). ImageFileCache is part of
 the MapControl library.
-* FileDbCache, an IDistributedCache implementation based on [EzTools FileDb](https://github.com/eztools-software/FileDb),
-a simple, file based No-SQL database, in a separate library FileDbCache.WPF.
-* SQLiteCache, an IDistributedCache implementation based on [System.Data.SQLite](https://system.data.sqlite.org/index.html/doc/trunk/www/index.wiki),

 If you want to try the sample application with persistent caching, uncomment the appropriate TileImageLoader.Cache
 setting in the sample application's MainWindow.xaml.cs file. Please note that some map providers may not allow
