MVVMexperiment wont build

Hi

I'm a bit new to this but I cannot get the sample project MVVMexperiment to build.

Initially I get two erroes in ListPage.xaml

DataListViewModel & DataViewModel do not exits in the clr-namespace :MVVMexperiment, which clearly they do.

When I build I get a thirs

The property 'InvokeMethod.Target' does not exist in XML namespace 'clr-namespace:Csla.Xaml=Csla.Xaml'

Could some kind soul point me in the right direction.

Cheers
Geoff

P.S. I have don a Clean and Build of the csla.all project as well as MVVMexperiment.
