如何使实体框架迁移使用web.config转换? [英] How do I make entity-framework migrations use web.config transforms?

问题描述

应用任何命令时

• 更新数据库"
• 添加迁移"

EF使用主要web.config中的连接字符串

The EF uses the connection string in your main web.config

即使您已使用xml转换配置了web.debug.config和web.release.config

even if you have configured web.debug.config and web.release.config with xml transformation

这意味着，我不得不冒险忘记发布真正的web.config，然后再发布.

This means, I have to go in and risk forgetting to change my true web.config back prior to a release.

推荐答案

我认为在本地运行web.config转换的唯一方法是使用带有以下参数的MSBuild，其中[YourTransformationConfiguration]是要使用的配置的名称，例如调试或发布:

I think the only way to run web.config transformations locally is to use MSBuild with the following parameters, where [YourTransformationConfiguration] is the name of the configuration to use, e.g. Debug or Release:

msbuild PathToProject /T:Package /P:Configuration=[YourTransformationConfiguration] /P:AutoParameterizationWebConfigConnectionStrings=False

其输出将在以下位置提供:

The output of which will be available at:

[ProjectFolder]\obj\[YourTransformationConfiguration]\Package\PackageTmp

从此处，您可以在程序集上运行migration.exe，这与运行Update-Database PowerShell脚本类似.如果您使用了Nuget，它将位于EntityFramework软件包的 tools 文件夹中.我在启动和运行时遇到了一些麻烦，但是这里有一个有用的答案Stack Overflow答案:

From here you can run migrate.exe on your assembly, which is similar to running the Update-Database PowerShell script. If you used Nuget, this will be in the tools folder of the EntityFramework package. I had some trouble getting this up and running, but there's a useful answer Stack Overflow answer here:

让Migrate.exe工作
