Hi,
I am using Visual Studio 2010 for Developing Applications, But it crashes if it get across unhandled Exceptions in VS10 and do not allow to debug the Exception.

I am Developing Simple Database Application. Backend as Oracle.
Normally this happens if there is error while opening Connection to Oracle.

If I surround con.Open() statement with try catch block all works fine.
I dont have any Addons or Special Components or References installed or Added in my project.

When i installed VS10 it was debugging unhandled Exceptions...

I Googled this problem but did not find helpfull answer.. Also tried to change settings in tools-options-debugging... but did not help!

please let me know proper solution..
