visual c++ 2008,应该下载什么呢？它的开发环境是啥？是visual studio 2008里面的一个吗？

Visual Studio2008整合开发环境，可以用于多种程式语言开发（C++，VB，C#等）。Visual C++2008内置于Visual Studio2008中。
现在一般都用Visual Studio 2012了。。。。。。。。

请问下用C# 2.0开发，其开发环境可以用visual studio 2008吗？还是一定要用visual studio 2005？谢谢

都可以。类库版本要可以改的，在专案属性里面。

Visual Studio 里面怎么退出原来的开发环境哦

工具——汇入和汇出设定

怎么把Visual Studio 2005 把预设的开发环境C#改为C++？

tools -> import and export settings... -> reset all settings

点工具选单,点选下面的汇入汇出设定,选择最后一项重置所有设定,就可以重新设定为C++开发环境了

visual C++ 2008 Express Edition是 Visual studio 2008的一个元件么?

Visual C++ 2008 Express Edition是一个微软提供的简化版本，Express Edition 中没有提供整合开发环境的大部分专业功能。

Visual studio 2017怎么切换开发环境

先在当前的开发环境中单击选单栏上的“工具”。
Visual studio 2017怎么切换开发环境
在弹出的下拉选单中选择“汇入和汇出设定”。
Visual studio 2017怎么切换开发环境
在“汇入和汇出设定”中选择”重置所有设定“，点选”下一步“。

在储存当前设定中可以将现在的设定进行储存，也可以不储存。设定完成后点选”下一步”。
Visual studio 2017怎么切换开发环境
接下来选择要切换到的整合开发环境，比如我之前是vc++，现在要使用vb开发环境。直接选择visual basic，然后点选完成即可。
