Again, it depends on what you are doing. If you are distributing apps that target the .Net Framework 4, then yes, it is beta and the customer should be told it's beta. If the customer wants to use new features, then they should be aware it's beta.
If you're just using VS2010 and targeting .Net Framework 3.5 or earlier, there is nothing beta the customer is using.
