ArcGIS map services stopped loading

Tasneem Mulla 6

ArcGIS map services stopped loading in Flash application since April 1st, 2022.

We see 404 HTTP error with host - dev.virtualearth.net , URL - /crossdomain.xml.

'404 - File or directory not found
The resource you are looking for might have been removed , had its name changed , or is temporarily unavailable.'

Have anyone experienced this issue? Please advise of any possible solutions.

I have exact the same problem.

Our customer noticed that since 01.04.2022 the maps are no longer loaded.
(On my developer machine I can reproduce this.)

Via Fiddler I see that clientaccesspolicy.xml and crossdomain.xml is returned with 404.

I have not currently found anything anywhere that would indicate an end to the interface via Silverlight.

Any work arounds for this issue? I have received some ideas from MS map team using a proxy server. For some reason this approach didn't work for us.

MS team reponse:

There is a Blog post that is still in a draft stage for how to hide your Bing Maps key using a proxy:
Hiding
To hide the Bing Maps key, you create a simple API endpoint that will only return the Bing Maps key if the request comes from a trusted referral URL. The Bing Maps Samples site is a good example that uses this approach.
In this example we are using an Azure Function written in C# that returns the Bing Maps key:

The Bing Maps key is stored server-side in this Azure Function Application settings field. We are using the GetEnvironmentVariable() to get the key.

Next, we need to load the Bing Maps script and get the key from the API client-side. Finally, we use the following code snippet to load Bing Maps dynamically:

The browser will run this code and create at runtime in the DOM the same line of script tag we have seen at the beginning of this blog post to load Bing Maps and the Key. An additional advantage is that the Bing Maps key is not stored in the source code anymore and that you can use IaC and build pipelines to deploy the solution.

The same method can be used to call any of the Bing Maps APIs. You would just need to have the xml files on the domain of your proxy server.

Yes. This is related to the EOL of Silverlight ( https://learn.microsoft.com/en-us/previous-versions/windows/silverlight/dotnet-windows-silverlight/cc197955(v=vs.95) ). Please move your app to either the V8 Web control or UWP Maps control. The Silverlight Maps control was deprecated in 2016 as documented here: https://www.microsoft.com/en-us/maps/discontinued-control-migration-guidelines

If you must rely on crossdomain, you can host your own server as a pass through and have that server call the API, but I believe this will only be a temporary fix and moving to a modern control is the right answer. We have a demo of how to use your own server to deploy your key https://greymatter.com/content-hub/protecting-and-hiding-your-bing-maps-key/ that can be extended to have the cross domain xml as well.
