nuget'packages'元素未声明为警告 [英] nuget 'packages' element is not declared warning

问题描述

不是topstopper，而是在项目中使用nuget时，它会创建具有这种形状的packages.config文件

not a showstopper but when using nuget in a project, it creates a packages.config file with this shape

<?xml version="1.0" encoding="utf-8"?>
<packages>
   ... your packages
</packages> 

这会在VS中发出警告

The 'packages' element is not declared.

问题的根源与我猜想的xml声明有关.

The origin of the problem got something to do with the xml declaration I guess.

我还认为默认定义包不应该发出警告.

Also I think that the default definition package shouldn't throw warnings.

有人知道我应该将其更改为什么，这样我就不会收到此警告吗? (即，即使我仅在打开文件时才能看到它，在某些CA规则启用的情况下，它也始终显示为警告.)

Does anyone know what should I change it to so I don't get this warning? (ie even if I can see it only when the file is open, it also shows as a warning constantly with certain CA rules on.)

推荐答案

您始终可以为"packages.config"制作简单的xsd模式，以消除此警告.为此，请创建名为"packages.xsd"的文件:

You can always make simple xsd schema for 'packages.config' to get rid of this warning. To do this, create file named "packages.xsd":

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
      targetNamespace="urn:packages" xmlns="urn:packages">
  <xs:element name="packages">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="package" maxOccurs="unbounded">
          <xs:complexType>
            <xs:attribute name="id" type="xs:string" use="required" />
            <xs:attribute name="version" type="xs:string" use="required" />
            <xs:attribute name="targetFramework" type="xs:string" use="optional" />
            <xs:attribute name="allowedVersions" type="xs:string" use="optional" />
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

此文件的位置(两个选项)

Location of this file (two options)

• 与"packages.config"文件位于同一文件夹中，
• 如果要在多个项目中共享packages.xsd，请将其移动到Visual Studio Schemas文件夹(路径可能略有不同，对我来说是D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas).

• In the same folder as 'packages.config' file,
• If you want to share packages.xsd across multiple projects, move it to the Visual Studio Schemas folder (the path may slightly differ, it's D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas for me).

然后，在packages.config文件中添加<packages>标签(添加xmlns属性):

Then, edit <packages> tag in packages.config file (add xmlns attribute):

<packages xmlns="urn:packages">

现在警告应该消失(即使在Visual Studio中打开了packages.config文件).

Now the warning should disappear (even if packages.config file is open in Visual Studio).
