System.Xml.XmlException: Encountered unexpected character '<'.

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.
