i have tested the "Managed Driver Beta".
It works well.
It really is a great relief to distribute only a reference.
I have a production system in a live environment.
It is very important that there are no disturbances.
Now to my question:
Is there really when using the "Managed Driver" no problems with already installed clients with earlier versions? e.g. ORANT?
Yep. It's nicely self-contained in its own assembly and namespace and doesn't impact on other things. If you really want to be paranoid about it, distribute it with your project instead of installing it on the server directly. That'll put it in your project's \bin folder and no other code will even realize it's there.
