如何使用MSBuild Task自动执行EF 4.3代码优先的SQL架构迁移脚本

Question

For the background context, we are using EF 4.3.1 code-first and migrations in MVC 3 application. In the past, we have done dev and staging deployments manually but now we are trying to automate the process to create dev and staging build using MSBUILD Tasks and TFS as source control.

My questions relates to above context as how can we generate sql migration script using EF migrations powershell commands "Update-Database -verbose -script" in MSBUILD tasks.

Is there any way to use native EF 4.3.1 migration commands in MSBUILD task to automate differential sql script generation ?

Thanks in advance for your inputs.

Answer 1

You should just call powershell: See Using Powershell scripts from MSBuild, Scheduled Tasks, etc

<Target Name="AfterBuild">
    <Exec Command="powershell.exe -command &quot;&amp; {.\Register-myscript.ps1 &apos;$(TargetPath)&apos;}&quot;" />
</Target>

您可以使MSBuild Task运行Migrate.exe，如此处所述， 如何使用MSBuild和Migrate.exe运行实体框架迁移

Answer 3

Here is a working version of the msbuild task. It copies migrate.exe from the tools folder of EF 6 into the build directory. In order for this to work all the paths are absolute.

  <Target Name="AfterBuild">
<copy SourceFiles="$(SolutionDir)packages\EntityFramework.6.1.3\tools\migrate.exe" DestinationFolder="$(TargetDir)" />
<exec Command="$(TargetDir)migrate.exe *YourData.dll* Configuration /startUpDirectory:$(TargetDir) /startUpConfigurationFile:$(TargetDir)WebStart.NET.dll.config /verbose"/>
</Target>
