In the time of great IDEs those code can be auto generated. But the language
itself looks more clean. This is only my own opinion. If you can live with
one keyword don't create two. :-)

I know they all have their usage and meanings. It looks like the designer of

Hehe, I don't in Java world there is a cry for property. :-))
I actually don't agree even with the first statement of the article.
"Developers arguing against properties typically fall into two categories.
There are those who oppose language changes in general and those who don't
want it simply because C# has them."
I think most people against it are not in either of these two categories.
Most people just want to keep the language simple and neat (less is more. :-
))

I agree. This is one approach of language design.
But sometime if one keyword has its natural meanings in different scenarios
maybe it is good to save some words. :-)
Like in Java, final can be used to define a constant, or if it is in front
of a method it means the method can not be overwritten.
Anyway, both approaches are fine. They are just the preference of the
designers and we have to follow.

internally, property is nothing but setter/getter.
you can argue that property does not bring too much to your class
implementation. but property is a syntax sugar to the client code which use
your class.
C#确实有很多的keywords. a lot of them are syntax sugar. 大部分还是很make
sense.

I assumed that you are comparing public variable and property. Think about
the followings:
1. What if you want to make a field readonly to other classes while writable
in the in the class it's defined.
2. What if you want to do something else(logging some information for
example) before writing to the field?
3. Think about the differences in reflection, intellisense and the

to evaluate an api fairly, you have to take into account
what users it targets. remember one of the goals
of .net is to bring users of different programming
languages to this common platform. it has to support
multiple programming styles to avoid imposing a
particular style on its users. with java this is
a non-problem because there's only one language,
so the language designer has much less to worry about
in terms of style.
