Silvlerlight 4 development using VS 2008

Question

My current software is based on Silverlight 3 and i am using VS 2008 and Blend 3 for development. With SL4 out in the wild, can i use my existing tool set (VS 2008 atleast) to develop SL4 code?

Answer 1

Unfortunately not. Silverlight 4 only works with Visual Studio 2010 and Blend 4.

Answer 2

It doesn't look like it's possible:

Ensure that you have the latest Visual Studio 2010 or Visual Web Developer Express 2010 installed as it is a prerequisite for developing Silverlight 4 applications using Visual Studio.
