asp.net-mvc - Web部署/发布是否添加了未知的连接字符串？

Question

以前发布我的网络api应用程序运行正常。今天，我将我的应用程序从“任何cpu”转换为x86。现在，当我发布其将添加字符串添加到Web配置时，这会导致我的应用程序失败。起初，我虽然可能会不小心将一些内容添加到web.config转换文件中，但我没有。这是我的转换文件:

<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>
  -->
  <entityFramework xdt:Transform="Replace">
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="Server=MyWebServer;Database=RunLog;Trusted_Connection=True; MultipleActiveResultSets=True" />
      </parameters>
    </defaultConnectionFactory>
  </entityFramework>

  <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>

这是我的网络配置文件:

      </parameters>
    </defaultConnectionFactory>
  </entityFramework>
</configuration>

最后，在我发布之后，这就是我的Web配置文件的样子:

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

    </handlers>
  </system.webServer>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">

  </entityFramework>
  <connectionStrings>
    <add name="RunLog" connectionString="RunLog_ConnectionString" providerName="System.Data.SqlClient" />
  </connectionStrings>
</configuration>

如果您在上面看，您会看到添加了一个连接字符串。

经过一番研究，我发现您可以添加一个连接字符串durinig publish。好吧，我一直使用相同的配置文件进行发布，因此我多次删除了该配置文件并创建了一个新的配置文件，并确保取消选中此框以添加连接字符串:

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

            <Source Path="DBContext" DbContext="RunLog.DL.RunLogContext, RunLog.DL" Origin="Convention" />

  </PropertyGroup>
  <ItemGroup>
    <MSDeployParameterValue Include="$(DeployParameterPrefix)RunLog-Web.config Connection String">

    </MSDeployParameterValue>
  </ItemGroup>
  <ItemGroup>
    <_ConnectionStringsToInsert Include="RunLog" />
  </ItemGroup>
</Project>

如您所见，那里有连接的东西，但是我特别取消选中“在运行时使用此连接字符串(更新目标Web配置)。如果我删除添加的连接字符串，则我的网站可以正常运行。

有人知道发生了什么吗？

编辑:
我以为也许我做错了什么，但是在今晚研究完之后，我认为这是一个错误。我决定回滚所有代码，看看是否可以重现该问题。以前，在属性的“打包/发布Web”选项卡中，选择了“包括在打包/发布SQL选项卡中配置的所有数据库:”。在“打包/发布SQL”选项卡中，在“数据库条目”中定义了一个连接字符串，但是如果我将其保留为空白，然后尝试发布一切正常，如果我删除了连接字符串并重新添加，则事情又一团糟了。在对话框中，您可以看到上面的数据库部分是否为空白，当您创建的配置文件，但如果它具有远程连接字符串框，则无法正常工作

通过编辑XML将此项目属性添加到.csproj文件:

<Project>
  <PropertyGroup>

    <AutoParameterizationWebConfigConnectionStrings>false</AutoParameterizationWebConfigConnectionStrings>

    ...
  </PropertyGroup>
  ...
</Project>

或者，使用此 related StackOverflow question中描述的Web发布管道目标文件。
