EF Core - 无源运行迁移 - 等效于 EF6 的 migrate.exe [英] EF Core - Running migrations without sources - Equivalent of EF6's migrate.exe

问题描述

是否可以从包含迁移和 dbcontext 的 DLL 运行 ef 迁移?我想针对我的构建工件运行 dotnet ef database update，而无需 project.json 和源代码.

Is it possible to run an ef migration from DLL containing migrations and dbcontext? I'd like to run dotnet ef database update against my build artefacts without need of project.json and source codes.

换句话说，我正在寻找等效的 migrate.exe https://msdn.microsoft.com/en-us/data/jj618307.aspx 来自 EF6

In other words I'm looking for an equivalent of migrate.exe https://msdn.microsoft.com/en-us/data/jj618307.aspx from EF6

推荐答案

我的团队同事找到了一种方法，允许您在没有源的情况下对构建工件运行迁移.以下命令为我们替换 migrate.exe:

My team colleague found a way which allows you to run migrations on build artefacts without sources. Following command replace migrate.exe for us:

dotnet exec 
  --runtimeconfig ./HOST.runtimeconfig.json 
  --depsfile ./HOST.deps.json Microsoft.EntityFrameworkCore.Design.dll
  --assembly ./DB_CONTEXT_DLL.dll 
  --startup-assembly ./HOST.dll --data-dir ./ 
  --root-namespace DB_CONTEXT_NAMESPACE 
  --verbose database update --context DB_CONTEXT_CLASS -e development 

2.1.x 版本更新:

Update for 2.1.x version:

dotnet exec 
   --runtimeconfig ./HOST.runtimeconfig.json 
   --depsfile ./HOST.deps.json /PATH/TO/microsoft.entityframeworkcore.tools/.../ef.dll 
   --verbose database update --context DB_CONTEXT_CLASS
   --assembly ./DB_CONTEXT_DLL.dll 
   --startup-assembly ./HOST.dll --data-dir ./
