问题描述
限时送ChatGPT账号..我正在使用 Visual Studio 2015 和 dotnet 核心,并尝试使用 Sqlite 开发 EF Core Code First 项目 和本文档/教程,它也使用 Sqlite =>
<块引用>未找到任何项目.更改当前工作目录或使用 --project 选项.
我什至尝试过像这样使用 --project
选项.
>dotnet --project "C:ShivaEFEFCFSqlite.Data.xproj" ef 迁移添加 InitialMigration
但这会产生以下错误.
未知选项:--project.NET 命令行工具 (1.0.0-preview2-003131)用法:dotnet [host-options] [command] [arguments] [common-options]
我注意到文档使用的是 .csproj
文件,而我的项目显示的是 xproj
文件.文档还提到不再使用 project.json
:(
这是我的 project.json
文件.
<代码>{"版本": "1.0.0-*",依赖关系":{"Microsoft.EntityFrameworkCore.Sqlite": "1.1.1","Microsoft.EntityFrameworkCore.Sqlite.Design": "1.1.1","NETStandard.Library": "1.6.1"},工具": {"Microsoft.EntityFrameworkCore.Tools.DotNet":"1.0.0"},构架": {netstandard1.6":{进口":dnxcore50"}}
发生了什么变化?我们别无选择,只能安装 Visual Studio 2017 并从头开始?project.json
和所有其他东西不再受到尊重吗?
如果是这样的话,对我来说似乎是一个巨大的变化:(
解决方案代替:
工具":{"Microsoft.EntityFrameworkCore.Tools.DotNet":"1.0.0"},
试试:
工具":{Microsoft.EntityFrameworkCore.Tools.DotNet":{版本":1.0.0-preview3-final"}},
I am using Visual Studio 2015 and dotnet core and trying to develop an EF Core Code First project using Sqlite and this documentation / tutorial, which also uses Sqlite => NET Core - New Database
When I try to add an initial migration from the command line ( I am CD-ed into the folder that my data model project is located in) by issuing the following command
dotnet ef migrations add InitialMigration
...I get the following Error.
No project was found. Change the current working directory or use the --project option.
I even tried using the --project
option like so.
> dotnet --project "C:ShivaEFEFCFSqlite.Data.xproj" ef migrations add InitialMigration
but that gives the following error.
Unknown option: --project
.NET Command Line Tools (1.0.0-preview2-003131)
Usage: dotnet [host-options] [command] [arguments] [common-options]
I noticed that the documentation is using .csproj
file whereas my Project is showing a xproj
file. Also the docs mention something about not using project.json
anymore :(
Here's my project.json
file.
{
"version": "1.0.0-*",
"dependencies": {
"Microsoft.EntityFrameworkCore.Sqlite": "1.1.1",
"Microsoft.EntityFrameworkCore.Sqlite.Design": "1.1.1",
"NETStandard.Library": "1.6.1"
},
"tools": {
"Microsoft.EntityFrameworkCore.Tools.DotNet":"1.0.0"
},
"frameworks": {
"netstandard1.6": {
"imports": "dnxcore50"
}
}
What has changed? Do we have no choice but to Install Visual Studio 2017 and start from scratch?? Is project.json
and all this other stuff no longer honored?
Seems like a massive change to me if that's the case :(
解决方案Instead of:
"tools": {
"Microsoft.EntityFrameworkCore.Tools.DotNet":"1.0.0"
},
try:
"tools": {
"Microsoft.EntityFrameworkCore.Tools.DotNet": {
"version": "1.0.0-preview3-final"
}},
