I am using .NET SDK v10.2.4, and recently I've started getting the following exception when trying to load basemap:
A first chance exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.dll
10:44:59 AM: System.Runtime.Serialization.SerializationException: There was an error deserializing the object of type Esri.ArcGISRuntime.ArcGISServices.MapServiceInfo. Encountered unexpected character '<'. ---> System.Xml.XmlException: Encountered unexpected character '<'.

The code to initialize basemap is like this:
private async Task InitializeBaseMapAsync(ArcGISTiledMapServiceLayer baseMap)
{
if (baseMap != null)
{
try
{
await baseMap.InitializeAsync();
if (baseMap.InitializationException != null)
{
...
}
else
{
...
}
baseMap.IsVisible = true;
}
catch (Exception ex)
{
...
}
}
Any help on whats going on or how I can resolve this issue will be greatly appreciated.
Thanks.
