silverlight-5.0

I am used to developing with N-Tier architecture, i.e. Data Access Layer, Business Logic Layer, etc Can anyone provide any advice or links about the best location for my business logic? Do I put all of this into classes within the Models folder of my Silverlight application? Paul Business logic, as well as the data, is typically part of the Model layer in MVVM. The View is the visuals, and the ViewModel is the "glue" that lets you work with the business specific logic and data. Anything that's specific to the domain or business should be reusable by other applications, using other

Is there any way, any chance at all to access entire filesystem in SL app with elevated trust? That will work both in Windows and Mac? Through AutomationFactory , PInvoke or unmanaged code? I need an app that could read local drives, folders and files. UDP: Ok, seems it's possible to read folders and files using classes of System.IO from mscorlib. Although you still can't get information about local mounted drives. There is no DriveInfo in Silverlight's mscorlib :( Ok I have an idea about this. It is straightforward enough with Windows, to get the list of the local drives you can use

Just installed SL5 and the toolkit, that were released few days ago. The bug happens when you set the Text property of the AutoCompleteBox to string.Empty. It causes the AutoCompleteBox to be in a buggy state. To reproduce the bug: add an AutoCompleteBox and a Button to the main page. Register to the TextChanged and Click events. This is the code-behind: public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); } private void button1_Click(object sender, RoutedEventArgs e) { auto.Text = string.Empty; } private void auto_TextChanged(object sender, RoutedEventArgs

I'm working on an ASP.NET website in which I'll need to access an usb device from the client side. I've seen that Silverlight 5, through the use of P/Invoke, allows us to access dlls on the client machine. I plan to add a silverlight control in one of my page that will interact with my usb Device. This, way, each customer using this kind of device, will only need to connect on my website and start working with it. Nonetheless, being a beginner at that kind of interaction with an usb device, how can I manage to do this ? Which windows dll will provide me with a good way of interacting with an

So far as I understand, SimpleIoc uses GetInstance method to retrieve an instance of a class that is registered. If the instance doesnt exist, it will create it. However, this instance is cached and always retrieved, which mimics the singleton pattern. My thinking is that there is no need to keep an instance of ViewModel in a memory if there is a small possibility that this ViewModel will be needed twice, so I would like to create new instance of it each time that is needed. If we have are having a factory for ViewModels, we will have a property like this: public MyViewMOdel MyViewModel { get
