Map Control provides three IDistributedCache implementations for persistent caching:
Map Control provides three minimal IDistributedCache implementations for persistent caching:
* 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, based on [EzTools FileDb](https://github.com/eztools-software/FileDb),

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
persistent caching of their map data.
You can of course also use a full-featured cache like
[RedisCache](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.caching.stackexchangeredis.rediscache?view=dotnet-plat-ext-3.1&viewFallbackFrom=dotnet-plat-ext-8.0).
To try the sample application with persistent caching, add an appropriate package reference to its Visual Studio project
and uncomment the respective TileImageLoader.Cache assignment in MainWindow.xaml.cs.
