Some .Net applications are required to run as single instance process (at startup, each process “ensures” that he’s unique). This requirement may come from licensing issues, technical and/or other reasons. Quick search in Google will provide a variety of solutions , most of them are based on WindowsFormsApplicationBase object from VB.Net, usage of Mutex object and other techniques. I don’t like mixing VB with C#, and also Win-Forms solution isn’t “pure” enough for WPF applications. So I wrote my...
This solution can be used in WPF and in WinForms (with some improvements). Many times UI programmer needs to activate window, the activation can be done by using “Activate()” function in window.

Silverlight is great technology with powerful graphic capabilities, allows us to build RIA s with animated 2D graphics, scalable controls, media playback, uses GPU acceleration, and much more. The Silverlight application can be developed in same environment as WPF ( Blend , Visual Studio , etc), has common principles of design as WPF (XAML, Namespaces, Syntax, etc). But, still it is different and targeted for cross-platform rich-client internet applications, the project from WPF can’t be ported easily...

The “ Keys Notificator ” is an open-source project and is a part of my community contribution under GNU General Public License . The published...
