问题描述

I am not an expert on this technology yet, so I guess for most this is a very basic question... But I don't really know how to use DBContext and how can I really connect my database, to the cross-platform solution file... and which nuget packages should I use?... where do I reference it?... what classes should I make and what codes do I put in it?... These questions, that I don't even know how to apply on my solution, I hope it doesn't bother you guys... 我还不是该技术的专家，所以我想大多数情况下这是一个非常基本的问题……但是我真的不知道如何使用DBContext，以及如何真正将数据库连接到跨平台解决方案。文件...我应该使用哪个nuget包？...我在哪里引用它？...我应该制作什么类以及应在其中添加什么代码？...这些我什至没有的问题知道如何应用我的解决方案，希望它不会打扰你们...

My goal is to make a datagrid using xaml grid, binded with sqlite database using entity framework core 2.1... 我的目标是使用xaml网格制作一个数据网格，并使用实体框架核心2.1与sqlite数据库绑定...

If you can answer my question in a step-by-step guide that would be really helpful for me... 如果您可以按照分步指南回答我的问题，那对我真的很有帮助...
