I have this strange problem when using the exception handling block of Enterprise library in my WCF Service.
I use de design mode to config the exception handling. When I test it everything works. But when I close the Config file and re-open it, the exception block is deleted in design.. (the code remains)
After a few runs or I don't know what it triggers, the code in the config file is also deleted.
I really have no idea what the problem could be.
The Validation block remains untouched and works fine so.. Every idea is very welcome!
