BingRestMapProvider
RadMap can visualize tile data from the Bing Maps REST service. You can enable tile caching to a local folder by setting a new LocalFileCacheProvider to the BingRestMapProvider.CacheProvider property.

You must provide a Bing Maps Key to the provider for it to work. To get your free Bing Maps Key, please refer to the following link: Getting a Bing Maps Key.
Only billable transactions count towards the free-use limits for Basic keys, and Enterprise keys are only charged for billable transactions. Non-billable transactions do not incur charges and do not count towards free-use limits. You can find additional information in the following link: Billable versus non-billable transactions.
BingRestMapProvider internally loads tile data from the Bing Maps REST service which requires TLS 1.2 coming automatically with .NET Framework 4.7. For older .NET Frameworks, or because of some other Windows settings, it may be necessary to explicitly choose TLS 1.2 for your application by setting the System.Net.ServicePointManager.SecurityProtocol property to SecurityProtocolType.Tls12. More information is available here: Transport Layer Security (TLS) best practices with the .NET Framework.
Using BingRestMapProvider
string cacheFolder = @"..\..\cache";
BingRestMapProvider bingProvider = new Telerik.WinControls.UI.BingRestMapProvider();
bingProvider.UseSession = true;
bingProvider.BingKey = bingKey;
LocalFileCacheProvider cache = new LocalFileCacheProvider(cacheFolder);
bingProvider.CacheProvider = cache;
this.radMap1.Providers.Add(bingProvider);
Dim cacheFolder As String = "..\..\cache"
Dim bingProvider As BingRestMapProvider = New Telerik.WinControls.UI.BingRestMapProvider()
bingProvider.UseSession = True
bingProvider.BingKey = bingKey
Dim cache As New LocalFileCacheProvider(cacheFolder)
bingProvider.CacheProvider = cache
Me.radMap1.Providers.Add(bingProvider)
If you use RadMap with .Net Framework 2.0 and you don't have an installation of the Telerik UI for WinForms suite on the current machine, it is necessary to add a reference to the Newtonsoft.Json assembly which can be found in the \Bin folder of the Telerik_UI_For_WinForms_[version]_Dev_dlls.zip. If you are using .Net Framework 4.0 this is not required.
