问题描述
将所有project.json文件升级到.NET核心的新格式后,我无法为Entity Framework 6迁移运行dotnet ef。有人可以看到下面的project.json有什么问题吗?
After upgrading all project.json files to the new format for .NET core I cannot run 'dotnet ef' for Entity Framework 6 migrations. Can anybody see what is wrong with the project.json below?
在我的project.json看起来像这样:
Before my project.json looked like this:
{
"frameworks": {
"dnx46": {
"dependencies": {
}
}
},
"dependencies": {
"EntityFramework": "6.1.3",
"EntityFramework.DynamicFilters": "1.4.8-*",
"Migrator.EF6": "1.1.0",
....
},
"commands": {
"ef": "Migrator.EF6"
}
}
现在看起来像这样:
{
...
"frameworks": {
"net46": {
"dependencies": {
}
}
},
"dependencies": {
"EntityFramework": "6.1.3",
"Microsoft.EntityFrameworkCore.SqlServer.Design": "1.0.0",
"EntityFramework.DynamicFilters": "1.4.8-*",
"Migrator.EF6": "1.2.0",
"Migrator.EF6.Tools": {
"version": "1.0.3",
"target": "package",
"type": "build"
},
...
},
"tools": {
"Migrator.EF6.Tools": {
"version": "1.0.3",
"imports": "portable-net45+win8+dnxcore50"
}
}
}
这是我当前运行的错误消息'dotnet ef':
This is the error message I currently have when I run 'dotnet ef':
推荐答案
你必须在你的 project.json
文件。
"buildOptions": {
"emitEntryPoint": true
}
另外,如果没有Main类添加这样一个空的主类:
Also, if you don't have a Main class add an empty Main class like this:
public class Program
{
public static void Main(string[] args)
{
}
}
