Parsing Command-Line Arguments with InstallContext

I'm using the InstallContext class to parse the command-line arguments of a console application. The arguments are in the form of "-file=myFile.txt -flag", and the InstallContext object gives me what I need through the Parameters and IsParameterTrue properties.

However, I can't find any documentation or code samples that confirm that this is an acceptable use of the InstallContext class. I understand the need to use Regex or some other means to parse more complex command-line arguments, but I'm surprised to find no mention of this simple parsing alternative. Is there anything wrong with using InstallContext for this purpose

using System;
using System.Configuration.Install;
using System.Collections.Specialized;

class MyClass
{
public static void Main(string[] args)
{
InstallContext context = new InstallContext(null, args);
StringDictionary parameters = context.Parameters;

string file = parameters["file"];
bool flag = context.IsParameterTrue("flag");

Console.WriteLine("file = {0}", file);
Console.WriteLine("flag = {0}", flag);
}
}
