在生产环境中尝试 运行 EF 代码优先 Migrate.exe 工具失败

Question

我正在使用 EntityFramework 版本 6.1.3。

我从EntityFramework版本6.1.3包工具文件夹复制migrate.exe到我网站的bin文件夹。

我的网站使用 x86 CPU 和目标框架 4.5.1

编译并发布到生产环境

我运行以下命令：

D:\Sites\MatrixPortal\bin>migrate.exe d:\sites\MatrixPortal\bin\MatrixPortal.BL.dll /startUpDirectory="d:\Sites\MatrixPortal\bin" /startUpConfigurationFile="d:\Sites\MatrixPortal\Web.config"

我收到以下错误：

ERROR: Could not load file or assembly 'd:\sites\MatrixPortal\bin\MatrixPortal.BL' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

编辑：

当我尝试这个时：

migrate MatrixPortal.BL.dll /verbose

我收到其他错误：

也试过这个： http://www.azurefromthetrenches.com/command-line-entity-framework-code-first-migrations/

并创建了一个名为 Redirect.config 的文件，内容如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
                                <bindingRedirect oldVersion="0.0.0-6.1.3" newVersion="6.1.3" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

但是得到了和上面一样的错误:(

Answer 1

已解决！

我已经发布了目标为 x86 的网站项目 cpu，显然它不是真正的 x86，我不知道为什么，也许是一个错误？

将 Publish 更改为任何 cpu 后它起作用了。我能够 运行 migrate.exe 使用以下参数没有错误：

migrate.exe MatrixPortal.BL.dll /verbose /startUpDataDirectory="D:\Sites\MatrixPortal" /startUpConfigurationFile="D:\Sites\MatrixPortal\Web.config"

Answer 2

在我的例子中，我得到了错误，因为我写了 migrate .\MyAssembly.dll 而不是 migrate MyAssembly.dll。

请参阅 Common Problems 文档部分。
