Answer 1

You have two choices:

• Recommend your clients install .NET 3.5 SP1 (nobody installs .NET 2.0 anymore)
• Target .NET 4.0 and ask your clients to install .NET 4.0 (this might not be accepted very well especially if your clients are some large corporations where company policy doesn't allow it)
