As you all know that, the Out-Of-Browser (OOB) functionality in Silverlight is not a new feature. It is available since Silverlight 3. Microsoft added the trusted application behaviour in Silverlight 4 Beta. In addition to this, they introduced one more additional functionality called “Chromeless OOB WIndow” i.e. “Customized OOB Window” in Silverlight 4 RC (Release Candidate). In this article, I will guide you to create a simple customized OOB Window Application in Silverlight 4 RC. After the end of this tutorial, you will be able to create a Customized OOB Window in Silverlight 4 which will look similar to this.

How can I develop Printing functionality using Silverlight 4?
Silverlight 4 now supports printing functionality using the Printing APIs. Using the APIs, you can now print your whole application screen or a portion of the application. Also, you can customize the look while you printing your part/full application.
In this post, I will step you guys to the depth of the printing API. Don’t forget to share your thoughts. Suggestions are always welcome. This will help me to improve my articles.

Breaking changes in Silverlight 4 RC
Microsoft has just released the Silverlight 4 RC with several changes in the Silverlight runtime & in the Silverlight tools. Though there are couple of changes since Silverlight 3 & since Silverlight 4 Beta but it supports most of the Silverlight 3 applications by using Quirks mode. In some cases your earlier application will break or behave differently.
In this post I will describe you both the breaking changes in Silverlight 4 since Silverlight 3 & Silverlight 4 Beta. But before going to the discussion on the breaking changes, let me tell you what is Quirks mode. Quirks mode is a behaviour by which your previous application will work on the new runtime. Simple example is that, if you have Silverlight 3 compiled application it will try to run in Silverlight 4 (some cases it will fail) using quirks mode but if you compile the same application in Silverlight 4 it will not use the quirks mode and through errors on the changes.
What’s new in Silverlight 4:
- XAP Signing
- Custom Chrome Window
- WebCam/Mic Configuration Preview
- Text position and Selection API
- Pinned full screen mode on secondary display
- Support for Private Browsing
- RichTextBox XAML clipboard format
- Elevated apps doesn’t have Sockets Security Restrictions
- Support for querying printer page size and printable area
- XmlnsPrefix & XmlnsDefinition attributes has been added
Breaking Changes since Silverlight 3:
So, lets start with describing the breaking changes in Silverlight 4 since Silverlight 3.
- Mouse Wheel Support - Silverlight 4 controls (ListBox, TextBox, ComboBox, ScrollViewer, Calendar, DatePicker, DataGrid) now have support for Mouse Wheel.
- Shared BitmapImage Source – Now Silverlight 4 will render the images properly if more than one Image controls are sharing the same BitmapImage source.
- ImageBrush.ImageSource returns ImageSource – ImageBrush.ImageSource in Silverlight 4 now returns ImageSource instead of UriSource which could be WritableBitmap or BitmapImage.
- Keyboard Navigation in TabControl – Keyboard navigation in TabControl was a feature in Silverlight 3 having an issue with the TabItem activation. Previously pressing Up Arrow activated the next TabItem and pressing Down Arrow activated the previous TabItem. In this release they fixed it to properly activate the TabItem. In Silverlight 4 if you press Up Arrow it will activate the previous TabItem & pressing Down Arrow will activate the next TabItem.
- Automation focus in DataGridCell - DataGridCell now receives automation focus when currency changes in the DataGrid, rather than focusing on the other part of the DataGrid.
- Hit Test while Toggling Full Screen Mode – While toggling full screen mode Silverlight 4 will now rerun hit testing. This allows controls that were under the mouse before toggling to update the MoouseEnter state if necessary.
- Whitespace handling with Span tag – TextBlock and RichTextArea now accepts text content & creates implicit runs generating whitespaces between inlines separated by CRLF.
- DisplayMemberPath & ItemTemplate recreates all containers – Silverlight 4 now recreates all containers by invalidating them while there is any change in DisplayMemberPath or in ItemTemplate properties of the ItemControl.
- New XAML Parser – Silverlight 4 now includes all new XAML Parser along with the previous XAML Parser. As per the runtime version detected in the application manifest it will parse the XAML in the appropriate parser. Apart from that, it has now additional benefits like “Better XAML compatibility”, “Greater parsing correctness & consistency”, “Better feedback error mechanism”, “Performance improvement”.
- Panels Clear() method calls InvalidateMeasure – If you call the Clear() method of the Silverlight 4 panel it will now explicitly call InvalidateMeasure.
- Virtualizing Stack Panel now scrolls by 3 lines – Mouse Wheel scroll in Silverlight 4’s Virtualizing Stack Panel will scroll by three (3) lines instead of one (1) line.
Breaking Changes since Silverlight 4 Beta:
If you were exploring Silverlight 4 Beta this section will be most important for you. There are some changes in both the runtime & tool since the beta release. So before starting with that please read the same carefully.
- Removed TextSelection.CanInsert – TextSelection.CanInsert is now no longer available in Silverlight 4.
- RichTextArea changed to RichTextBox – RichTextArea now renamed to RichTextBox.
- RichTextBox.TextDecorations no longer exists – RichTextBox.TextDecoration is not available now. Instead of it you can use Inline.TextDecorations.
- Default value to RichTextBox.TextWrapping – Silverlight 4 now has a default value of RichTextBox.TextWrapping to Wrap. If you don’t want to wrap your content you have to explicitly set it to NoWrap.
- HtmlBrush renamed to WebBrowserBrush – In Silverlight 4 HtmlBrush now renamed to WebBrowserBrush.
- COM Interoperability – COM Interoperability types are now moved to System.Runtime.InteropServices instead of System.Windows.Interop namespace.
- WebCam/Output Protection Support – There has been a huge changes in the webcam/output protection support:
- CanEnableHDCP renamed to CanEnableHdcp
- CanEnableCGMSA renamed to CanEnableCgmsa
- VGA, DVI, HDMI, LVDS, SDI, UDIExternal, UDIInternal also renamed to similar naming convention
- VideoFormat.Height and VideoFormat.Width renamed to VideoFormat.PixelHeight and VideoFormat.PixelWidth respectively
- AsyncCaptureImage call now changed to CaptureImageAsync
- NotificationWindow – NotificationWindow.Visible property has been changed to NotificationWindow.Visibility

Visual Studio 2010 Features – Better Productivity
Multi-targeting Application Development:
Using Visual Studio 2010 you can not only develop applications for the .Net 4.0 but also can use it for the development of earlier versions of the framework. While creating a new project in the IDE you will see the option to select between different types of .Net Framework (i.e. 2.0, 3.0, 3.5 & 4.0).
Depending upon your choice it will filter the project templates in the New Project dialog. If you select “.Net Framework 4.0” it will show all the project types but if you select “.Net Framework 2.0” it will only show the projects supported by .Net Framework 2.0.
Not only this, as Visual Studio 2010 builds on top of Windows Presentation Foundation (WPF), you will find it more useful while searching for a specific project type. Suppose, you want to develop an application for your client in WPF & you are finding it very difficult to search within a huge collection of project types. Don’t worry. There is a “Search Box” right to the dialog for you to help finding the same. Just enter the keyword (in this case “WPF”) & see the magic. While typing, it will auto filter based on the keyword you entered.
Faster Intellisense Support:
Visual Studio now came up with faster intellisense support. It is now 2-5 times faster than the earlier versions. The IDE will now filter your intellisense as you type. Suppose, you want to create an instance of “WeakReference” & due to the search algorithm of the VS2010 IDE, you don’t have to write the full word of the Class. Just type “WR” and it will automatically filter out that & show you “WeakReference” in the intellisense. Try it out.
You will find this feature useful while you are showing some presentation or doing a webcast. Earlier VS2010 you have to open the options panel & then you have to change the font size of the editor, which was little bit troublesome. Now that issue is gone. You don’t have to follow where to go to change the text size. While inside the editor window, just press the control key (CTRL) and use your mouse wheel to increase/decrease the zoom level.
Faster Assembly loading in “Add Reference”:
In Visual Studio 2010 loading of assemblies in the “Add Reference” dialog is pretty fast. In earlier versions, it freezes the dialog for some time to load all the assemblies. In 2010 IDE, by default it focuses on the “Project” tab & in the background loads the other tabs. In case it is opening the dialog focusing on the “.Net” tab you will notice that instead of loading all the assemblies at a time, it loads those in a BackgroundThread. Thus improving the loading time a bit faster.
As you can see, I don’t have a class named “Person” in my project and hence it is marking it as UNKNOWN by highlighting it in Red. If you look into the first snapshot in depth you can find out that though the class is not present in my namespace or even in the project, it is creating the class reference in the intellisense. Great, right? Wait a minute. If you now place you cursor on top of “Person” and press F10 while holding down ALT+Shift, you will see a dropdown comes up in the screen with two menu item asking you to either generate the class for you or generate a new type.
Here in the example, the public keywords of the properties has been marked using the Box Selector and when typing, it is actually changing in all the lines. Have a look into the second snap where I am typing “internal” to replace “public” and that’s populating in all the lines where I marked.
Fix for Visual Studio 2010 RC Intellisense Crash
Microsoft has released two hot fixes till now for Visual Studio 2010 RC crash related to intellisense. The people who are currently using Visual Studio 2010 RC in a machine having UI Automation 3.0 APIs, touch screen, screen reader etc. have to download & install the following two HotFixes:
If you need any more information on the fixes then get it here at MSDN Blog.
