With dynamic keyword, you wouldn't have to know the strong type of one object. In fact, without having to know the type in advance, you can use this as you expected: a variable can be anything .

For example, I could declare a method like this:

    static void DynamicTest(dynamic arg)
    {
        Console.WriteLine(arg.aaa);
    }

DynamicTest accessed aaa field(or property) in arg without knowing that whether arg itself has aaa or not. Using a dynamic means that you don't want compiler to detect the possible errors that you may or may not access something from a variable that does not actually have it.

You can call this method with:

DynamicTest(new {aaa = "I am accessible"});

it'll run, also you can call this method with:

DynamicTest(1); // I will cause runtime exception

So, in your specific situation, you could define the variable result as dynamic since you now know that you'll get a variable that contains several properties that you want to use.

var res = shell.Invoke()[0];
dynamic obj = res.BaseObject;

Therefore you can use it like a regular variable(without IntelliSense of course).

Console.WriteLine(obj.Build); // Now I can compile yay!

Here.
