+### Automatic Debugger Break On Exception
+When running your Solutions with a Debugger attached e.g. [VSCode](https://code.visualstudio.com/docs/editor/debugging) or [Visual Studio](https://docs.microsoft.com/en-us/visualstudio/debugger/quickstart-debug-with-managed?view=vs-2019) the ASolution base class will try to pause/break the debugger when there is an uncaught Exception thrown by your solution part. This allows for inspection with the debugger without having to specifically set-up additional exception handling within the debugger or your solution.
