EventToCommand don't exist in Mvvmlight toolkit WPF4.5

Question

I\'m using the latest MVVMLight Tookit at version 4.1.26.24928, and I\'m writing a program using WPF 4.5.

Now I can\'t use the EventToCommand in VS2012 XAML file, it say

Answer 1

I had a similar problem, using VS2013. Mine said:

EventToCommand does not exist in the namespace "http://www.galasoft.ch/mvvmlight"

Which sounded like nonsense since everything seemd to match... and the project was runing after rebuild/clean/whatever.

Solution:

1) Using NuGet (right-click on project in Solution Explorer) I uninstalled the "MVVM Light Libraries only" (it asked if I wanted to uninstalled the related CommonServiceLocator, I said: yes, whatever)

Rebuild, (just in case) It gave a lot of errors as expected, the ones about EventToCommand were still there.

2) Using NuGet I now installed the "MVVM Light Libraries only". Rebuilt and now it works. No errors, no warnings, rock on ;-)
