In our application we are experiencing crashes, freezes, and failure to load the basemaps when the map control is loaded/unloaded multiple times during the maps lifecycle. (Loading/unloading of a control may happen normally in WPF for many reasons, the most common is probably if the control is inside a TabControl. )
The only error message we are receiving is "The program ' MyApp.exe' has exited with code -529697949 (0xe06d7363) 'Microsoft C++ Exception'." in the output window.
I've attached a sample application that demonstrations the issue. The sample has two methods to reproduce the issue:
1) Automatic - It will automate the switching of tabs/adding & removing graphics. This has consistently reproduced the issue on 3 separate dev enviroments (win 10 x64). It takes approx 20 seconds to execute.
2) Manual - This will reproduce the issue on 2 out 3 of our dev enviroments (all win 10 x64). Steps included in the sample.
The sample also includes a flag called m_EnableMitigation which will activate code that helps mitigate the issue by removing and re-adding graphics layers to the map when it is loaded. We've called this a mitigation rather than a work around because it does not work 100% of the time. Its still possible to cause the issue if the control is loaded/unload very quickly by manually switching tabs or programmatically.
I think our issue may possibly be related to this post as well: https://community.esri.com/message/763969-re-application-crash-frequent-win32-exceptions-in-1002?commentID=763969#commen…
Please let me know if there is anyway to fix this issue. We will not be able to ship our application with this bug the way it is.
