本文介绍了为什么要升级到c＃4.0？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我知道在C＃4.0有一些不错的新功能，但我不能，在我的生活，想到一个引人注目的原因，升级现有的项目或切换到新的项目。I know there are some nice new features in C# 4.0 but I can't, for the life of me, think of a compelling reason for either upgrading existing projects or for switching to new projects.我看过一些帖子，有人说如果他们的主机服务没有提供.Net 4，他们会找到另一个提供商.Net 4是他们的方向微小<？> 。I've seen some posts where people have said that if their hosting service didn't provide .Net 4 that they'd find another provider as .Net 4 was pinicle to their direction <?>.现在我的老板想让我同意将我们所有的生产环境切换到C＃现在做。Now my boss is trying to get me to agree to switch all our production environments to C# 4 and to do it now.所以问题是有人开始使用或转换一个项目，C＃4有一个令人信服的理由？So the question is has anyone either began using, or converted a project to, C# 4 for a compelling reason? Was there a feature that you just had to have that would make your life so much easier?推荐答案有一些很酷的 C＃4.0中的新功能： 动态成员查询 协变和逆向通用类型参数 使用COM时可选参考关键字 可选参数和命名参数 已编入索引的属性Dynamic member lookupCovariant and contravariant generic type parametersOptional ref Keyword when using COMOptional parameters and named argumentsIndexed properties后Scott Guthrie详细介绍了 .NET 4的功能一般。另一个重要资源是 http://www.asp.net/learn/whitepapers/aspnet4上的白皮书。但是，我怀疑你会立即需要这些新功能。 Scott Hanselman博客：In his release blog post Scott Guthrie goes into detail about the features of .NET 4 in general. Another great resource is a white paper at http://www.asp.net/learn/whitepapers/aspnet4. However, I'd doubt you are going to need one / any of these new features right away. As Scott Hanselman blogged:因此，您是否应该升级取决于各种其他因素。有些原因让人想起：Whether or not you should upgrade is therefore dependent on a variety of other factors. Some reasons that spring to mind: 在vs2008的单一平台VS2010上标准化您的开发环境。与你的经理进行公开对话似乎是适当的，以了解他的升级的推理。我认为，因为它的光泽不是一个引人注目的原因。An open dialogue with your manager seems appropriate to understand his reasoning for the upgrade. I'd argue that because it's shiny isn't a compelling reason.作为参考这个日期的Stack Overflow问题为什么不升级到最新的.net框架提供了与你的问题相反。As a reference this dated Stack Overflow question "Why not upgrade to the latest .net framework" provides the inverse to your question. 这篇关于为什么要升级到c＃4.0？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
