问题描述
我使用 Visual Studio 通过某种迁移来更新我的所有环境.使用下面的命令运行良好.
I use visual studio to update all my environments with a certain migration. It had worked fine using the command below.
update-database -Migration initMigrationProduct -c ProductContext -Environment Production
在 ef core 2.0 中，此命令已更改，参数 -Environment 已删除.在它说的文档中.
In ef core 2.0 this command has been changed and parameter -Environment has been removed. In the docs it said.
"在 2.0 中，您可以使用 ASPNETCORE_ENVIRONMENT 环境变量而是."
"With 2.0, you can use the ASPNETCORE_ENVIRONMENT environment variable instead."
https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet
我现在尝试了各种方法，但是当我使用 ef core 2.0 运行 update-database 时，它不使用 ASPNETCORE_ENVIRONMENT 变量.我尝试在注册表中设置应用程序属性.
I have now tried all kinds of ways but when I run the update-database with ef core 2.0 it doesn't use the ASPNETCORE_ENVIRONMENT variable. I tried to set in registry, application properties.
请让我知道我需要做什么才能使其工作以更新不同的环境?
Please let me know what I need to do to get this working to update different environments?
如果我使用不同的 launchsettings 启动应用程序，它可以工作，但不使用包管理器控制台.
If I start the application with different launchsettings it works but not using the package manager console.
推荐答案
在 Visual Studio 中使用包管理器对我来说是一条死胡同.解决方案是:
Using the package manager in Visual Studio was a dead end for me. The solution was:
在解决方案的启动项目中的.csproj 中添加以下内容:
Add below in .csproj in the starter project in solution:
<ItemGroup>
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
</ItemGroup>
打开命令工具(cmd)，进入与.csproj相同的文件夹，用于启动项目(默认项目).
Open the command tool(cmd) and go the the same folder as .csproj for start project are located(Default project).
按照 Anton Toshik 的建议运行命令set ASPNETCORE_ENVIRONMENT=Production
Run the command as Anton Toshik suggested set ASPNETCORE_ENVIRONMENT=Production
4.然后运行命令dotnet ef database update initMigrationProduct -c ProductContext 现在可以了.
4.Then run the command dotnet ef database update initMigrationProduct -c ProductContext And now it works.
REMARK:在此命令中，database 和 update 与早期版本相比已更改位置.并且没有用于迁移的参数/代码.澄清后，文档进行了更多解释:
https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet
REMARK: in this command database and update have changed place since earlier versions. And there are no argument/code for migration. The docs explain more after this clarification:
