Question

以前发布我的web api应用程序工作得很好。今天我将我的应用程序转换为＆＃34;任何cpu＆＃34;到x86。现在，当我发布它向web配置添加连接字符串时，这导致我的应用程序失败。起初我虽然我可能会意外地在web.config转换文件中添加一些东西，但是我还没有。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>

最后我发布之后这就是我的网络配置文件：

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

如果你看上面你会看到添加了一个连接字符串。

经过一些研究后我发现你可以添加一个连接字符串durinig publish。好吧，我已经使用相同的配置文件发布，所以我多次删除配置文件并创建一个新的配置文件，并确保取消选中该框以添加连接字符串： Publishing

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

正如你所看到的，那里有连接内容，但我特意取消选中＆＃34;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，我的网站将完美运行。

有谁知道最近发生了什么？

编辑：
我想也许我做错了什么但是在今晚完成它之后我才认为这是一个错误。我决定回滚所有代码，看看我是否可以重现问题。以前在＆＃34;包/发布网站＆＃34;属性中的选项卡＆＃34;包括在包/发布SQL选项卡中配置的所有数据库：已选中。在＆＃34;包/发布SQL＆＃34;选项卡在＆＃34;数据库条目＆＃34;中定义了一个连接字符串。但它的空白。如果我保持原样并尝试发布一切都很完美。如果我删除连接字符串并重新添加它会再次搞砸了。在上面看到的对话框中，如果数据库部分为空白，则在创建配置文件时一切正常，但如果它具有远程连接字符串框，那么事情就不会出现。工作正常

Answer 1

通过编辑XML：

将此项目属性添加到.csproj文件中

<Project>
  <PropertyGroup>

    <AutoParameterizationWebConfigConnectionStrings>false</AutoParameterizationWebConfigConnectionStrings>

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

或者，按照此related StackOverflow question中的说明使用Web发布管道目标文件。

Answer 2

对我有用的解决方案，虽然它更像是一个黑客，但是使用Web部署转换来删除恶意连接字符串。见user2395249回答：

One-click publish in vs 2012: how to remove _ConnectionStringsToInsert?

Answer 3

在.pubxml文件中，出于某种原因添加了一些额外的连接字符串。删除所有这些，它应该工作正常，仍然会添加默认的连接字符串。

我有一种预感，当我使用我的发布信息稍微调整一下时，已将其添加到.pubxml中，但当我切换回常规发布设置时，它没有被删除。

<ItemGroup>
    <MSDeployParameterValue Include="$(DeployParameterPrefix)DefaultConnection-Web.config Connection String" />
    <MSDeployParameterValue Include="$(DeployParameterPrefix)MyProject-Web.config Connection String" />
    <MSDeployParameterValue Include="$(DeployParameterPrefix)MyProject_dev-Web.config Connection String" />
  </ItemGroup>
  <ItemGroup>
    <_ConnectionStringsToInsert Include="MyProject" />
    <_ConnectionStringsToInsert Include="Myproject_dev" />
  </ItemGroup>

Answer 4

编辑项目.csproj文件并添加此文件：

<PropertyGroup>
<InsertAdditionalWebCofigConnectionStrings>false</InsertAdditionalWebCofigConnectionStrings>

对我有用。

Web Deploy / Publish是否添加了未知的连接字符串？
