IMHO, the most impactful feature is LINQ and lambda expressions

blocks|key|544298|text|在3.0中，WCF可能是最通用的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|544299|WPF很好，但是windows/UI是特定的。|544300|在3.5，LINQ一路;-|544301|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

In 3.0, WCF is probably the most versatile for general usage.

WPF is fine, but is windows/UI specific.

In 3.5, LINQ all the way ;-

blocks|key|544325|text|取决于你的需求，但我认为兰巴斯和林克非常有趣。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|544326|特别提到LINQ和LINQ，因为它们显示出您在DB之外也具有查询功能。|544327|我还认为WPF真的很酷，WCF使进程间通信更加容易。|544328|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Depends on your needs, but I' d say Lambdas and LINQ is very interesting.

A special mention of LINQ-to-objects and LINQ-to-XML, because they show you have query capabilities also outside the DB.

I also think WPF is really cool, and WCF makes interprocess comunication a lot easier.

blocks|key|544409|text|查看C#汽车属性-比LINQ或lambda表达式简单得多的概念，但将节省大量时间和麻烦！|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|544410|entityMap^0|2|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

blocks|key|2073760|text|来自C#+3.0:部分方法。它们是编程语言中最重要的一个特性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2073761|不，我开玩笑的:+lambda表达式和LINQ会改变你对编码的看法。当您不得不为没有它们的平台编写代码时，它们也会使您非常想念它们：|2073762|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

From C# 3.0: partial methods. They're the single most important feature to grace a programming language, ever.

Nah, I'm kidding: lambda expressions and LINQ will change the way you look at coding. They'll also make you miss them greatly when you have to code for a platform which doesn't have them :(

blocks|key|544264|text|首先也是最重要的：林克|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|544265|entityMap|0|LINK|mutability|MUTABLE|url|http://www.programmersheaven.com/2/CSharp3-4^0|9|2|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

First and foremost: <a href="http://www.programmersheaven.com/2/CSharp3-4" rel="nofollow noreferrer">LINQ</a>

blocks|key|544356|text|林克很漂亮。要了解LINQ的一点是，它不仅仅是关于数据库的，它是一种集合查询功能，它通过LINQ和LINQ实体连接到它上。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|544357|WPF很有趣。|544358|对象初始化器使生活变得如此简单..。|544359|MyObject+foo+=+new+MyObject()+{prop1="foo",prop2="bar"}|code-block|syntax|javascript|544360|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|O|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|P|8|@]|9|@]|A|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

LINQ is nifty. The thing to understand about LINQ is that it's not just about databases, it's a collection-querying capability that has ORM bolted onto it with LINQ to SQL and LINQ to Entities.

WPF is interesting.

Object initializers make life SO easy...

<pre><code>MyObject foo = new MyObject() {prop1="foo",prop2="bar"}
</code></pre>

blocks|key|544483|text|如果您主要做的是“图形化”的事情，那么WPF可能是最好的关注对象。如果你在做基于网络的开发，别忘了这是“小弟弟”银光。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|544484|如果您以前使用过.NET远程处理或Web，那么WCF无疑是未来的发展方向。|544485|如果您正在执行数据库类型的应用程序，那么林克+(特别是LINQtoSQL)就是您所追求的目标。不过，小心使用LINQtoSQL，将来很可能会被LINQtoENTITIES取代(作为实体框架的一部分)。|544486|请注意，LINQ是一种更广泛的技术，可以应用于XML、对象，实际上，您可以编写自己的提供程序，以便允许LINQ-to-任何您想要的内容！(例如，优秀著作Linq+In+Action的作者在书中写了一个)。|544487|作为一种广泛的技术，LINQ是由其他底层技术改进(如可拓方法和Lambda表达式+)而成为可能的，所以如果您想深入研究LINQ，您也可以学习这些技术！这反过来又会导致像表达树这样的事情，当您想真正了解“幕后”发生了什么的时候。|544488|总的来说，我认为LINQ是最好的关注对象。它有许多多种用途(即不专注于一个或两个特定的“领域”的开发)，建立在.NET语言的许多其他技术改进的基础上，而且将来可能会有更多的改进(即Lambda表达式是在C#中引入更多“功能”语言的开始！)|544489|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Windows_Presentation_Foundation|1|http://en.wikipedia.org/wiki/Silverlight|2|http://en.wikipedia.org/wiki/Windows_Communication_Foundation|3|http://en.wikipedia.org/wiki/Linq|4|http://en.wikipedia.org/wiki/Entity_Framework|5|http://msdn.microsoft.com/en-us/library/bb383977.aspx|6|http://msdn.microsoft.com/en-us/library/bb397687.aspx|7|http://msdn.microsoft.com/en-us/library/bb397951.aspx^0|J|3|0|1K|2|1|0|N|3|2|0|K|2|3|2I|4|4|0|0|Q|4|5|V|9|6|2C|3|7|0|0^^$0|@$1|2|3|4|5|6|7|19|8|@]|9|@$A|1A|B|1B|1|1C]|$A|1D|B|1E|1|1F]]|C|$]]|$1|D|3|E|5|6|7|1G|8|@]|9|@$A|1H|B|1I|1|1J]]|C|$]]|$1|F|3|G|5|6|7|1K|8|@]|9|@$A|1L|B|1M|1|1N]|$A|1O|B|1P|1|1Q]]|C|$]]|$1|H|3|I|5|6|7|1R|8|@]|9|@]|C|$]]|$1|J|3|K|5|6|7|1S|8|@]|9|@$A|1T|B|1U|1|1V]|$A|1W|B|1X|1|1Y]|$A|1Z|B|20|1|21]]|C|$]]|$1|L|3|M|5|6|7|22|8|@]|9|@]|C|$]]|$1|N|3|-4|5|6|7|23|8|@]|9|@]|C|$]]]|O|$P|$5|Q|R|S|C|$T|U]]|V|$5|Q|R|S|C|$T|W]]|X|$5|Q|R|S|C|$T|Y]]|Z|$5|Q|R|S|C|$T|10]]|11|$5|Q|R|S|C|$T|12]]|13|$5|Q|R|S|C|$T|14]]|15|$5|Q|R|S|C|$T|16]]|17|$5|Q|R|S|C|$T|18]]]]

If you're primarily doing "graphical" things, <a href="http://en.wikipedia.org/wiki/Windows_Presentation_Foundation" rel="nofollow noreferrer">WPF</a> is probably the best thing to focus on. And don't forget it's "little brother" <a href="http://en.wikipedia.org/wiki/Silverlight" rel="nofollow noreferrer">Silverlight</a>, if you're doing web-based development.

If you've previously done things with .NET Remoting or Web Services, then <a href="http://en.wikipedia.org/wiki/Windows_Communication_Foundation" rel="nofollow noreferrer">WCF</a> is definitely the way to go for the future.

If you're doing database type applications, then <a href="http://en.wikipedia.org/wiki/Linq" rel="nofollow noreferrer">LINQ</a> (and specifically LINQtoSQL) is what you'll be after. Be careful with the LINQtoSQL, though, could well be replaced with LINQtoENTITIES in the future (as part of the <a href="http://en.wikipedia.org/wiki/Entity_Framework" rel="nofollow noreferrer">Entity Framework</a>).

Note that LINQ is a much broader technology, though, and can be applied to XML, Objects, in fact, you could write your own provider to allow a LINQ-to-anything if you want! (The authors of the excellent book, Linq In Action write a LINQ-to-Amazon in it, for example).

As a broad technology, LINQ is made possible by other underlying technological improvements like <a href="http://msdn.microsoft.com/en-us/library/bb383977.aspx" rel="nofollow noreferrer">Extension Methods</a> and <a href="http://msdn.microsoft.com/en-us/library/bb397687.aspx" rel="nofollow noreferrer">Lambda Expressions</a>, so if you want to really delve into LINQ, you can learn these, too! This in turn leads onto things like <a href="http://msdn.microsoft.com/en-us/library/bb397951.aspx" rel="nofollow noreferrer">Expression Trees</a> for when you want to really know what's going on "under the covers".

Overall, I'd say LINQ is the best thing to focus on. It's got many multiple uses (i.e. Not focused on one or two specific "areas" of development), is built upon a whole bunch of other technological improvements in the .NET languages, and moreover, will probably be built upon even more in the future (i.e. Lambda expressions are the start of introducing more of a "functional" language into C#!)

blocks|key|806266|text|有4个新的语言特性特别重要。作为开发人员，语言是您所能(和不能)做的一切的基础，因此理解这四个重要的新语言特性是非常重要的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|806267|我要说的四个特点是：|806268|可拓方法|ordered-list-item|806269|Lambda表达式|806270|隐式局部变量|806271|匿名类型|806272|(注:还有其他一些新的语言特性，当然它们很重要。但这4是我首先要讨论的基础问题)。|806273|现在，它正好是这样，LINQ主要是基于这四个功能。如果你真的想掌握+3.0，那么除了在Linq.中使用这些语言特性之外，您还需要更深入地理解这些语言特性。|806274|一旦你做到了这一点，你就可以做两件事了：|806275|利用C#+3.0编写一些功能强大的代码|806276|真正理解林克。|806277|尽情享受吧！C#+3.0是一件很漂亮的事情。|806278|entityMap^0|5|2|0|0|0|0|0|0|0|X|F|1S|D|0|0|K|0|0|J|0|0|7|0|0|M|0^^$0|@$1|2|3|4|5|6|7|14|8|@$9|15|A|16|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|17|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|18|8|@]|D|@]|E|$]]|$1|K|3|L|5|J|7|19|8|@]|D|@]|E|$]]|$1|M|3|N|5|J|7|1A|8|@]|D|@]|E|$]]|$1|O|3|P|5|J|7|1B|8|@]|D|@]|E|$]]|$1|Q|3|R|5|6|7|1C|8|@]|D|@]|E|$]]|$1|S|3|T|5|6|7|1D|8|@$9|1E|A|1F|B|C]|$9|1G|A|1H|B|C]]|D|@]|E|$]]|$1|U|3|V|5|6|7|1I|8|@$9|1J|A|1K|B|C]]|D|@]|E|$]]|$1|W|3|X|5|J|7|1L|8|@$9|1M|A|1N|B|C]]|D|@]|E|$]]|$1|Y|3|Z|5|J|7|1O|8|@$9|1P|A|1Q|B|C]]|D|@]|E|$]]|$1|10|3|11|5|6|7|1R|8|@$9|1S|A|1T|B|C]]|D|@]|E|$]]|$1|12|3|-4|5|6|7|1U|8|@]|D|@]|E|$]]]|13|$]]

There are 4 new language features that are particularly important. The language is the foundation of everything you can (and can't) do as a developer, and therefore understanding these 4 important new language features is very important.

The 4 features I'm talking about are:

<ol>
<li>Extension methods</li>
<li>Lambda expressions </li>
<li>Implicitly typed local variables</li>
<li>Anonymous types</li>
</ol>

(Note: There are other new language features as well, and they're important of course. But these 4 are the foundational ones I would start with).

Now, it just so happens that LINQ is based mostly on these 4 features. But don't let that throw you off course. If you really want to master C# 3.0, you need to understand each of these language features deeply, apart from their usage in Linq. 

Once you've done that, you're in a fantastic position to do 2 things:

<ol>
<li>Utilize C# 3.0 to write some
powerful code</li>
<li>Actually understand Linq.</li>
</ol>

Enjoy it! C# 3.0 is a beautiful thing.

There are quite a few <a href="http://en.wikipedia.org/wiki/.NET_Framework#Versions" rel="nofollow noreferrer">features</a> a .NET developer needs to brush up on to get up to speed. 

I am still on 2.0, probably becuase of the industry I work in, where Banks tend to hold back on using bleeding edge technologies (in my experience).

Developers who have experience of .NET 3.0 or greater, what features (both language and frameworks) would you recommend to look at first ?
