It is often a requirement to open the default web browser and browse to a specific Url from a Windows Forms, WPF or even Console application. The easiest method I’ve discovered is to make use of the System.Diagnostics.Process class:
static void Main(string  args)
Process .Start("http://softwarebydefault.com" );
In most scenarios the code snippet listed above works without a problem. The only issue I foresee being in an environment where the user account used to execute your application not having sufficient permissions to execute the default browser application.
