Question

I have just installed the components for MVVM item and created a project for WP7 (this is in VS10)

getting ‘unable to load the metadata for assembly ‘mvvmLight1’ Then points me to a web reference that effectively tells me I need to unblock the file. But I did this as part of the installation, and, I have checked and itthe file are not appearing as Blocked.

The offending line is in the App.xaml

xmlns:vm="clr-namespace:MvvmLight1.ViewModel" and causes the following error

Error 1 Unable to load the metadata for assembly ‘MvvmLight1’. This assembly may have been downloaded from the web. See http://go.microsoft.com/fwlink/?LinkId=179545. The following error was encountered during load: Could not load file or assembly ‘MvvmLight1’ or one of its dependencies. The system cannot find the file specified.

I must have done something wrong in the installation, but have no idea what. Any advice appreciated. Thanks

EDIT

had not altered anything from the template when I loaded it… but.. have changed as you suggested… so it looks like

xmlns:vm="clr-namespace:GalaSoft.MvvmLight.Command;
assembly=GalaSoft.MvvmLight.Extras.WP7"> 
<!--xmlns:vm="clr-     namespace:MvvmLight1.ViewModel"-->
<!--Application Resources--> <Application.Resources>
<vm:ViewModelLocator    x:Key="Locator"

but now see the following error Error 1 The type ‘vm:ViewModelLocator’ was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

So not sure where to go from here

Answer 1

you have wrong namespace declaration… compare this (wrong)

xmlns:vm="clr-namespace:MvvmLight1.ViewModel" 

to this (right)

xmlns:cmd="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.WP7"

you missed assembly declaration…
