执行code首先迁移 [英] Execute Code first Migration

问题描述

我已经安装了Windows 8.1 Pro和使用VS 2013社区版感动了所有MVC项目，以新的工作空间。所有项目都是使用code第一次迁移。
数据库发布使用code第一次迁移也做。所有运行良好我更新了我的机器前。

I have installed Windows 8.1 pro and moved all MVC projects to new work-space using VS 2013 Community Edition. All projects were using code first migration. Database Publishing was also done using code first migration. All was running fine before I updated my machine.

但现在，当我发布web应用到远程服务器，发布网站对话框不显示执行code第一次迁移，而不是它的表现更新​​数据库更新数据库。
当我关闭它，它会修改发布文件DB第一。看来，一些全局设置，它执行以下code：

But Now when I publish web application to remote servers, 'Publish Web' dialog box not showing "Execute Code first Migration", Instead its showing "Update database" for updating database. And when I close it, It modifies the publish files for DB First. It seems that some global setting enforcing it to the following code:

 <Objects xmlns="">
        <ObjectGroup Name="DefaultConnection" Order="1" Enabled="False">
          <Destination Path="" />
          <Object Type="DbDacFx">
            <PreSource Path="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\MVC-20140923125211.mdf;Initial Catalog=MVC-20140923125211;Integrated Security=True" includeData="False" />
            <Source Path="$(IntermediateOutputPath)AutoScripts\DefaultConnection_IncrementalSchemaOnly.dacpac" dacpacAction="Deploy" />
          </Object>
          <UpdateFrom Type="Web.Config">
            <Source MatchValue="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\MVC-20140923125211.mdf;Initial Catalog=aspnet-MVC-20140923125211;Integrated Security=True" MatchAttributes="$(UpdateFromConnectionStringAttributes)" />
          </UpdateFrom>
        </ObjectGroup>
      </Objects>

没有显示我的所有项目它的奇怪为什么执行code第一次迁移。

Its strange why "Execute Code first Migration" is not shown for all my projects.

此行​​为是一样的我所有其他项目了。

This behavior is same for all my other projects too.

App_Data文件数据库还没有打开。因此，我改变的connectionString'数据源从数据源=（的LocalDB）\\ V11.0 到数据源=（的LocalDB）\\ MSSQLLocalDB（MSSQL Sever的2014前preSS） 。更改数据源工作虽然打开数据库。

The App_Data databases also not opening. So I changed connectionString' datasource from Data Source=(LocalDb)\v11.0 to Data Source=(LocalDb)\MSSQLLocalDB (MSSQL Sever 2014 express). Changing DataSource worked for opening database though.

我试过的解决方案：

• 尝试这样做：<一href=\"http://stackoverflow.com/questions/19664459/execute-$c$c-first-migrations-checkbox-disappeared-from-my-publish-profile\">"Execute code首先迁移＆QUOT;复选框从我的发布配置
消失

• 启用迁移-Force


• 清洁，重建并重新启动项目，
  Visual Studio中。


• 删除并重新导入文件发布

我试过上面几个月前解决方案。彼时上述几点工作，但现在没有什么工作。

I tried solutions above few months back. That time the points above worked but now nothing works.

是否有可用于该解决的办法？我浪费了我整整一天，仍然没有找到解决办法。

Is there any solution available for this? I wasted my whole day and still not found solution.

推荐答案

我发现这是一个临时解决方案。手动替换所有的ConnectionString名（Defaultconnection）上下文名ApplicationDbContext没有命名空间解决了这个问题。

I found a temporary solution for this. Manually replacing all ConnectionString name (Defaultconnection) to context name "ApplicationDbContext" without namespaces solved the problem.
