Feddas - Shawn Featherly

I ran into several issues while getting MVVM Light V3 (http://www.galasoft.ch/mvvm/installing/manually/) to work with VS 2010 ver 10.0.30319.1 and the first Release version of WP7 Tools.
The major difference is the Navigation namespace is now inside the Microsoft.Phone.Controls namespace.

Following are the steps I took to add an MVVM Light WP7 project to run.

Changes to Project References
Add reference to
Microsoft.Phone
Microsoft.Phone.Interop

remove refrence to
Microsoft.Phone.Controls.Navigation


Changes to WMAppManifest.xml
the "L" in silverlight is no longer a capital letter, Change case of RuntimeType value to
Silverlight

remove instance of
PlaceHolderString="Default task"


Changes to Permissions on .dll's
Error messages may pop up saying .dll's are flagged from being downloaded from the web.
-Navigate to the files in explore
-right click an offending file
-select properties
-on the "General" tab click "Unblock" near the bottom.


Changes to App.xaml
remove from App.xaml
xmlns:phoneNavigation="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Navigation"
and


Source="/MainPage.xaml" />


Add to App.xaml.cs
the usings
using Microsoft.Phone.Controls;
using System.Windows.Navigation;
and

public App()
{
  ...keep code already in there and add lines below
 // Phone-specific initialization
 InitializePhoneApplication();
}
        #region Phone application initialization
        /// 

        /// Provides easy access to the root frame of the Phone Application.
        /// 

        /// The root frame of the Phone Application.
        public PhoneApplicationFrame RootFrame { get; private set; }

        // Avoid double-initialization
        private bool phoneApplicationInitialized = false;

        // Do not add any additional code to this method
        private void InitializePhoneApplication()
        {
            if (phoneApplicationInitialized)
                return;

            // Create the frame but don't set it as RootVisual yet; this allows the splash
            // screen to remain active until the application is ready to render.
            RootFrame = new PhoneApplicationFrame();
            RootFrame.Navigated += CompleteInitializePhoneApplication;

            // Handle navigation failures
            RootFrame.NavigationFailed += RootFrame_NavigationFailed;

            // Ensure we don't initialize again
            phoneApplicationInitialized = true;
        }

        // Do not add any additional code to this method
        private void CompleteInitializePhoneApplication(object sender, NavigationEventArgs e)
        {
            // Set the root visual to allow the application to render
            if (RootVisual != RootFrame)
                RootVisual = RootFrame;

            // Remove this handler since it is no longer needed
            RootFrame.Navigated -= CompleteInitializePhoneApplication;
        }

        // Code to execute if a navigation fails
        private void RootFrame_NavigationFailed(object sender, NavigationFailedEventArgs e)
        {
            if (System.Diagnostics.Debugger.IsAttached)
            {
                // A navigation has failed; break into the debugger
                System.Diagnostics.Debugger.Break();
            }
        }
        #endregion

Changes to MainPage.xaml
remove
xmlns:phoneNavigation="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Navigation"

add
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

change phoneNavigation:PhoneApplicationPage to phone:PhoneApplicationPage on both the top of the page and the bottom

Edit: This didn't fix everything, there are issues such as the ListViewItem being replaced by the ListBoxItem. I recommend following the link Laurent Bugnion commented below, where he's already done all the work for us. If you're really curious of all the changes do a diff between the templates.
