Handling corrupting exceptions is not supported .NET Core

[jkotas]

Handling corrupting exceptions is not supported .NET Core

Version introduced

.NET Core 1.0

Old behavior

Exceptions corrupting process state could be caught and handled by managed exception handlers (e.g. try/catch in C#).

New behavior

Corrupted process state exceptions cannot be handled by managed code.

Reason for change

Handling of corrupting exceptions is insecure and impossible to do with high reliably in managed code.

Recommended action

Avoid need for handling corrupting exceptions by addressing the situations that leads to them instead. If it is absolutely required to handle corrupting exceptions, the handler should be written in C/C++.
