Final answer:
Carefully read and agree to the Visual Studio 9.0 Beta 1 License Agreement when receiving the pre-release software, and cease using it if you disagree with the terms.
Step-by-step explanation:
When you receive pre-release software as part of the Visual Studio 9.0 Beta program, it's important to carefully read and agree to the accompanying license terms. By using the software, you are indicating that you understand and accept the terms of the Visual Studio 9.0 Beta 1 License Agreement.
If you do not agree with the terms stipulated in the license, you are obliged to cease using the software and delete all copies of the electronic work.
In the event that you paid a fee to obtain the pre-release software and decide that you do not agree with the terms of the agreement, you may be eligible to receive a refund from the entity to which the fee was paid, as described in the terms of the agreement.
