Bug #34082 Code execution prevention in Connection class

Description:
In Connection class in "internal void SetState" method
code execution never gets to line 417
while changing state to Connected by Open method.
All registered StateChange delegates get  only Connecting state.

How to repeat:
Register a System.Data.StateChangeEventHandler and call Open method.

Suggested fix:
Add 
SetState(ConnectionState.Connecting, false); 
into Open method, just after line 478 "driver.Configure(this);"

Sorry, here is really working fix.
On line 498 Connection.cs
******************************************************
hasBeenOpen = true;
SetState(ConnectionState.Connecting, false);
SetState(ConnectionState.Open, true);

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

The status of connections reported through the state change handler was not being updated correctly
