What I need to remember from Today!

C# ArrayList is used when there is a need for variable size array: using System; using System.Collections; namespace ConsoleApplication1 {     class Program     {         static void Main( string [] args)         {             ArrayList List1 = new ArrayList ();             ArrayList List2 = new ArrayList ();             List1.Add( "B" );             List1.Add( "A" );             List1.Add( "C" );             Console .WriteLine( "Shows Added valuess" );            ...

The name of the starting xaml page for the Windows Phone 7 application is in the Properties\WMAppManifest.xml file: . . .     < Tasks >       < DefaultTask   Name = " _default " NavigationPage = " MyStartXamlPage.xaml " />     </ Tasks > . . .

Press on the “Page UP” key and start typing!

I tried to debug a Windows Phone 7 application in Visual Studio 2010 when I received the error “Zune Software is not installed. Install the latest version of Zune software”, it turned out I did not select the correct deployment target for the project, I had “Windows Phone 7 Device” selected instead of “Windows Phone 7 Emulator.
