The prereqs for Simple MVVM 3.0 lists VS2010 SP1,
and also SL 4 Tools.
But attempting to install SL4 after SP1 gives error:
Visual Studio 2010 or Visual Web Developer Express 2010 or Visual Phone Developer Express 2010 that matches the language version of Silverlight Tools 4 must be installed before installation of Silverlight Tools can continue.
And various posts I've found seem to indicate that VS2010 SP1 already includes SL 4 tools., but the SL4 installer gets confused when SP1 has already been installed.
So do I really need to install SL4 tools? And if so, how?
