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

问题描述

不是一个炫技，但在项目中使用 nuget 时，它会创建一个具有此形状的 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 中给出警告

this gives a warning in VS

The 'packages' element is not declared.

我猜问题的根源与 xml 声明有关.

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

另外我认为默认定义包不应该抛出警告.

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

有谁知道我应该将其更改为什么，这样我就不会收到此警告?(即即使我只有在文件打开时才能看到它，它也会在某些 CA 规则开启的情况下不断显示为警告.)

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 架构来消除此警告.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)

• 在与packages.config"文件相同的文件夹中，
• 如果您想在多个项目之间共享 packages.xsd，请将其移至 Visual Studio Schemas 文件夹(路径可能略有不同，它是 D:Program Files (x86)Microsoft Visual Studio 10.0XmlSchemas 适合我).

• 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 10.0XmlSchemas for me).

然后，编辑packages.config文件中的标签(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 packages.config 文件在 Visual Studio 中打开).

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