配置元素未声明 [英] The configuration element is not declared

问题描述

我做在Visual Studio 2012前preSS版的一些工作。我已经添加了一个app.config的XML文件如下：

I'm doing some work in Visual Studio 2012 Express Edition. I have added an App.config XML file as follows:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
</configuration>

这发生的第一件事情是一个警告来了，说：'配置'元素未声明。有谁知道为什么发生这种情况？它看起来像元素不能，直到这个解决内部声明。

The first thing that happens is a warning comes up that says "The 'configuration' element is not declared". Does anyone know why this is happening? It looks like elements can not be declared inside of until this is resolved.

谢谢！

这是整个XML：

推荐答案

我有同样的问题。这是不是一个错误，它只是一个警告;所以你的应用程序应该仍然编译。我用下面这个简单的配置文件，警告仍然产生。

I had the same issue. It is not an error, it is simply a warning; so your application should still compile. I used the following simple config file and the warning is still produced.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime 
             version="v4.0"sku=".NETFramework,
             Version=v4.5"/>
    </startup>
</configuration>

这是已提出的MSDN网站上的一个问题，但它似乎并没有被很好的解决。见下面的链接：

It is an issue that has been raised on the MSDN website, but it does not seem to have been satisfactorily resolved. See link below:
