ASP.Net 3.5 站点可以在装有 ASP.Net 4.0 的服务器上运行吗？
在服务器上安装了 4.0 ASP.Net 框架，但我正在制作的网站适用于 3.5。我是否还需要安装 3.5 框架才能使页面正常工作？
Can an ASP.Net 3.5 site run on a server with ASP.Net 4.0 on it?
On the server it has the 4.0 ASP.Net framework installed on it but the site I am making is for 3.5. Do i need to have 3.5 framework installed too to make the page work?

是的，确实如此，但很可能，3.5 框架应该已经安装了。如果没有，请确保已安装它。
但是，通常最好按顺序安装版本...过去，我曾遇到过先安装 4.0 后安装“较小”版本，或者先安装 2.0 后安装 1.1 的问题。按照正确的顺序安装它们是一个很好的做法。
Yes, it does, but in all likelihood, the 3.5 framework should already be installed. If not, ensure that it gets installed.
However, it's usually best to install the versions in order... I have had issues in the past when 4.0 was installed first and a "lesser" version afterward, or when 2.0 was installed before 1.1. It's just good practice to install them in the correct order.
所有.net框架安装程序都包含以前的版本，包括服务包。如果您直接从微软网站下载它们，它们就会这样做，这确保了它是最新版本。
我从来没有安装过多个版本（1.1，然后2.0，然后3.0等等）..总是最新的，我从来没有遇到过问题。但是，如果您确实遇到问题，该方法可能会有所帮助。
All .net framework installers include the previous version including the service packs.. well they do if you download them directly from microsoft's website which ensures its the newest version.
I've never installed multiple version (1.1, then 2.0, then 3.0 and soforth).. always just the newest and I've never encountered a problem. However if you do get issues that approach might be helpful.
