尝试使用添加迁移新的项目...... [英] Trying to use add-migration a new projet...

问题描述

嗨专家。我目前尝试添加迁移来为我的项目创建SqLite类。在另一个项目上，一切都很好，但是对于这个项目，我使用了更新的UWP版本（14393）和视觉工作室2017.

Hi expert. I currently try to add-migration to create the SqLite class for my projet. On another projet all is working good, but for this one, I use a newer UWP build (14393) and visual studio 2017.

我按照这个链接  https://docs.microsoft.com/en-us/ef/core/get-started/uwp/getting-started

I follow this link https://docs.microsoft.com/en-us/ef/core/get-started/uwp/getting-started

并添加

• Microsoft.EntityFrameworkCore.Sqlite
• Microsoft.EntityFrameworkCode.Tools

然后剪切和粘贴y model.cs代码和我的所有表格代码。然后运行add-migration InitialDB

then cut ans paste y model.cs code and all my table code. Then run add-migration InitialDB

我总是遇到这个错误：

System.Reflection.TargetInvocationException：目标调用引发异常。 ---> System.TypeInitializationException：'KelvinPunch.SqLite.PunchContext'引发异常。 ---> System.DllNotFoundException：无法加载DLL的'sqlite3'

System.Reflection.TargetInvocationException: Exception raise by target call. ---> System.TypeInitializationException: Exception raise by 'KelvinPunch.SqLite.PunchContext'. ---> System.DllNotFoundException: Cannot load DLL 'sqlite3'

DLL在bin文件夹中！有什么帮助吗？

the DLL are in the bin folders! Any help?

PS：我将重新安装VS2015并尝试使用它。

PS: I will reinstall VS2015 and try with it.

推荐答案

嗨皮埃尔，

SQLite不是微软的产品，我知道有一些文档可供使用，例如

https://docs.microsoft.com/en-us/windows/uwp/data-access/sqlite-databases  。

SQLite is not a Microsoft product but I do know there are some docs on it's use such as https://docs.microsoft.com/en-us/windows/uwp/data-access/sqlite-databases .

也许在其他论坛中有一些帖子可以提供帮助？
https://social.msdn.microsoft.com/论坛/ en-US / home？sort = relevantdesc& brandIgnore = True& searchTerm = SQLite

Maybe there are some postings in other forums that would help? https://social.msdn.microsoft.com/Forums/en-US/home?sort=relevancedesc&brandIgnore=True&searchTerm=SQLite

更有可能是所有事情的最佳来源SQLite是他们自己的网站，因为他们有自己的开发论坛如果您查看其支持链接，请 http://sqlite.org/ 。

More likely the best source for all things SQLite is their own site as they do have their own dev forum http://sqlite.org/ if you look under their support link.

此致，
