I would like to react to the application

Answer 1

To check for a Forms, WPF, WCF or Console application:

if (System.Windows.Forms.Application.OpenForms.Count > 0)
{
    return ApplicationType.WindowsForms;
}

if (System.Windows.Application.Current != null)
{
    return ApplicationType.Wpf;
}

if (System.ServiceModel.OperationContext.Current != null)
{
    return ApplicationType.Wcf;
}

try
{
    int windowHeight = Console.WindowHeight; // an exception could occur
    return ApplicationType.Console;
}
catch (IOException)
{
}

return ApplicationType.Unknown;
