If you REALLY want to create a business object from a string (rather than using the conventional strongly typed approach using "new", you need to use reflection. You would have to pass both the class name and assembly name to the method as follows:

public IMyInterface CreateBizObject(string assemblyName, string className)
{
	// Load the assembly to use.
	Assembly asm = Assembly.LoadFrom(assemblyName);

	// Get the Type of the specified class
	Type ObjectType = asm.GetType(className, true);

	// Creates an instance of the specified type
	return (IMyInterface)Activator.CreateInstance(ObjectType);

}

Obviously, the problem with this approach is that you won't catch errors until run time since the compiler can't do type checking on this code. For example, if you pass a "className" that does NOT implement IMyInterface, you will get an "invalid cast" exception at run time.
