As discussed, the problem happens with
[System.Exception]-derived types as well, except for[System.Management.Automation.RuntimeException], which is what PowerShell implicitly uses when you throw nothing or any object that is not an exception.BrucePay commentedon Mar 14, 2018
The
.WasThrownFromThrowStatementproperty along withRuntimeExceptionare implementation details for the PowerShell runtime and aren't intended to be used by end users..WasThrownFromThrowStatementexists so that thethrowstatement can throw an exception that won't be caught by pipeline exception handlers allowing the exception to propagate up through a set of nested pipelines. Since it's PowerShell-specific, it won't appear on any non-PowerShell types.alx9r commentedon Mar 14, 2018
Thanks for the clarity Bruce Payette (@BrucePay)
