WPF Splash Screen

Why don't you just google for "WPF splashscreen". I get tons of results.
For example these 2 directly from CodeProject:

Thank you for your answer but I saw the following at "http://msdn.microsoft.com/en-us/library/cc656886.aspx":

To add an existing image as a splash screen
1.Create or find an image that you want to use for the splash screen. You can use any image format that is supported by the Windows Imaging Component (WIC). For example, you can use the BMP, GIF, JPEG, PNG, or TIFF format.
2.Add the image file to the WPF Application project. For more information, see How to: Add Existing Items to a Project.
3.In Solution Explorer, select the image.
4.In the Properties window, click the drop-down arrow for the Build Action property.
5.Select SplashScreen from the drop-down list.
Note
If you do not see the SplashScreen option, be sure to check that you are using Visual Studio 2008 SP1 or later.

I am using Visual Studio 2010 and I thought the above looked simpler than having to write code.

>"why "Splash Screen" is not listed as a "Build Action" option in my system"

First of all, you're most probably using wrong terminology: most likely, what you have in mind is Visual Studio "Template", the actions taken when you perform the operation "Add" in your Solution Explorer at a solution or project node of the tree. Less likely you meant a "Build Action" because is a notion of build system, specific to a separate project node (representing a file) -- see MSBuild documentation for comprehensive information.

Probably, "Splash Screen" is not "listed" anywhere, because there is no special need in it. There is nothing special about a component which can serve as a splash screen. Most typically, this is a WPF Window or System.Windows.Forms.Form with specially adjusted properties and appropriate handling of some events.

If you simply paid more attention to the other Answers, you would not have to ask additional question on the topic; and I would not need to write mine.
