• To get rid of warnings like:

Type of 'Blah.Blah.Blah' is not CLS-compliant

when you have a separate assembly for models, etc, add the following line to AssemblyInfo.cs in the library (ie non-UI) assembly:

[assembly: CLSCompliant(true)]

• Silverlight 4 design-time sample data. Add a static collection to the view model, and set the following as the parent datacontext, remember to set ItemsSource to {Binding name_of_static_property_which_is_the_sample_collection}:

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
d:DataContext="{d:DesignInstance local:ViewModelClassName, IsDesignTimeCreatable=True}"

• To fix problem with default Silverlight BusinessApplication template generated projects and Windows authentication, override the AuthenticationService GetAuthenticatedUser method in the web project, like this (add "using System.Web.Configuration;"):

       // Have to override GetAuthenticatedUser when using Windows authentication.
       // Even when Windows auth is defined, the auth subsystem insists on looking for an
       // AspNetProvider SQL database. Code below gets the user information from the 
       // principal in the Windows Auth case.
       protected override User GetAuthenticatedUser(System.Security.Principal.IPrincipal principal)
       {
           User user = new User();
           Configuration config = WebConfigurationManager.OpenWebConfiguration("~");
           SystemWebSectionGroup grp = (SystemWebSectionGroup)config.GetSectionGroup("system.web");
           AuthenticationSection auth = grp.Authentication;
           if (auth.Mode == AuthenticationMode.Forms)
           {
               user = base.GetAuthenticatedUser(principal);
           }
           else if (auth.Mode == AuthenticationMode.Windows)
           {
               string[] a = principal.Identity.Name.Split('\\');
               //System.DirectoryServices.DirectoryEntry ADEntry = new System.DirectoryServices.DirectoryEntry("WinNT://" + a[0] + "/" + a[1]);
               //string Name = ADEntry.Properties["FullName"].Value.ToString();
               user.Name = a[a.Length-1];
           }
           return user;
       }

• Dropshadow effect (in Resources):

<DropShadowEffect x:Key="DropShadow"  
               BlurRadius="15" 
               Color="Black" 
               Direction="320"
               Opacity="1.0"
               ShadowDepth="10" />

• • To use (in xaml):

Effect="{StaticResource DropShadow}"

• • To use (in .cs):

 control.Effect = Application.Current.Resources["DropShadow"] as System.Windows.Media.Effects.Effect

• To get position of a UIElement:

// Obtain transform information based off root element
UIElement element = this as UIElement;
GeneralTransform gt = element.TransformToVisual(Application.Current.RootVisual);
// Find the four corners of the element
Point topLeft = gt.Transform(new Point(0, 0));
Point topRight = gt.Transform(new Point(element.RenderSize.Width, 0));
Point bottomLeft = gt.Transform(new Point(0, element.RenderSize.Height));
Point bottomRight = gt.Transform(new Point(element.RenderSize.Width, element.RenderSize.Height));
