In your call to Activator.CreateInstanceFrom, you've specified the
*namespace* and then type name, rather than assembly and then *full*
type name.

However, you don't need to use that version anyway. It's simpler to
use:

Activator.CreateInstance("ConsoleApplication1.A");

Note that if the type were in a different assembly, you'd use something
like:

Activator.CreateInstance("MyAssembly.dll", "ConsoleApplication1.A");

Oops - although you could, you might be better to load the assembly
separately, then use loadedAssembly.CreateInstance(typeName) instead,
to save the object unwrapping. (Frankly, I still don't entirely
understand ObjectHandles etc...)
