推荐答案

一个简单的谷歌搜索错误将为您提供许多方法来解决这个问题。



一个可能的问题是，IIS可以设置为以.Net 3.5或更早版本运行，并且您的web.config中有.Net 4项。由于有许多事情可以导致它，你需要经历每一种可能性并弄明白。



因为它适用于你的电脑我的猜测你在IIS中设置了错误的.Net版本。

A simple google search of the error will give you lots of ways to fix this.

One possible issue is that IIS could be set to run as .Net 3.5 or earlier and you have .Net 4 items in your web.config. Since there are many things that can cause it, you'll need to go through each of the possibilities and figure it out.

Since it works on your PC my guess is you have the wrong .Net version set in IIS.
