Web.config 转换不转换 VS 2017

Question

我确实取消了样板代码的注释，并尝试发布到文件系统以检查“转换”是否有效。

但是，它不会转换 web.config 文件。我在这里查看了一些文章和答案，但无法正常工作。

我尝试过的事情：

Removing the namespace from the configuration node(complains about xdt missing)
Creating a new transform file(production)
Creating a new configuration(production)

这里是 web.Release.config：

<?xml version="1.0"?>

<!-- For more information on using Web.config transformation visit https://go.microsoft.com/fwlink/?LinkId=301874 -->

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <!--
    In the example below, the "SetAttributes" transform will change the value of
    "connectionString" to use "ReleaseSQLServer" only when the "Match" locator
    finds an attribute "name" that has a value of "MyDB".

    <connectionStrings>
      <add name="MyDB"
        connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
        xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
    </connectionStrings>
  -->
      <connectionStrings>
      <add name="MyDB"
        connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
        xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
    </connectionStrings>
  <system.web>
    <compilation xdt:Transform="RemoveAttributes(debug)" />
    <!--
      In the example below, the "Replace" transform will replace the entire
      <customErrors> section of your Web.config file.
      Note that because there is only one customErrors section under the
      <system.web> node, there is no need to use the "xdt:Locator" attribute.

      <customErrors defaultRedirect="GenericError.htm"
        mode="RemoteOnly" xdt:Transform="Replace">
        <error statusCode="500" redirect="InternalError.htm"/>
      </customErrors>
    -->
  </system.web>
</configuration>

我收到以下错误：

No element in the source document matches '/configuration/connectionStrings/add[@name='MyDB']'

但正如您所见，它存在于添加节点中。

有什么建议吗？我很困惑为什么它不起作用。

编辑： web.config 连接字符串

<connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=.\SQLExpress;database=smartDB;Integrated Security=True" providerName="System.Data.SqlClient" />
  </connectionStrings>

Answer 1

name 属性的值需要在 web.config 和 web.release.config 之间匹配，因为您在转换配置中指定了 Match(name)。

在您的 web.config 中，您有：name="DefaultConnection" 在您的 web.release.config 中：name="MyDB"
