This RC doesn’t support Silverlight 4.

But of course it doesn’t mean that Visual Studio 2010 RTM will not, it will.

See you at Visual Studio 2010 RTM, Silverlight 4…

Edit: Based on the following ScottGu's post, the next version of Silverlight 4 will be supported by VS 2010 RC (note that currently Silverlight 4 still BETA)
