MA0161 - UseShellExecute must be explicitly set

Detects when Process.Start is called without specifying the value of UseShellExecute.

Specifying the value is important because the default value for this property is true on .NET Framework apps and false on .NET Core apps. It's a common issue when migrating a desktop app from .NET Framework to .NET Core.

using System.Diasgnostics;

// Non compliant

Process.Start(new ProcessStartInfo("cmd")); // Intent is not clear if you want to use ShellExecute or not

Process.Start(new ProcessStartInfo("https://www.meziantou.net/")); // Will fail on .NET Core apps

// Compliant

Process.Start(new ProcessStartInfo("https://www.meziantou.net/")
{
    UseShellExecute = true,
});
