Tools used : .NetFramework Beta 2, Editplus.
Introduction
Microsoft had made lot of Changes for Beta2, some of the changes are old Namespace such as System.WinForms modified to System.Windows.Forms. In addition no. of new Namespaces like Microsoft.CSharp, Microsoft.JScript, Microsoft.Vsa etc... are added. In Beta2, namespace Microsoft.Win32.Interop is integrated with mscorlib library, so no need to use this library while compiling, whereas it is compulsory in Beta1.
TimeTicker sample application can be compatible with Beta2 with the following modifications.
1) Change namespace System.WinForms to System.Windows.Forms
2) Change BorderStyle property to FormBorderStyle
3) Change the Methods FromHWND to FromHwnd and FromARGB to FromArgb
