引用的项目依赖项DLL不被复制

本文介绍了引用的项目依赖项DLL不被复制的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我的项目解决方案当前有三个项目：My project solution is currently having three projects: MyProject ，这是我的主要启动项目（使用 .NET Framework 4.7 ）-WPF，UI特定， MyProject.Core -类库（ .NET Standard 2.0 ）-保存模型以及所有幕后数据 MyProject.Relational -类库（ .NET Standard 2.0 ）-负责处理和保存数据库的特定信息MyProject, which is my main startup project (using .NET Framework 4.7) - WPF, UI specfic,MyProject.Core - class library (.NET Standard 2.0) - holding the models, and all of the 'behind the scenes' dataMyProject.Relational - class library (.NET Standard 2.0) - responsible for processing and saving the database specific informations项目 1 （主要）已设置对项目 2 和 3 。Project 1 (main) has set a reference to project 2 and 3.对于项目 3 我已经安装了 Microsoft.EntityFrameworkCore.Sqlite（2.0.3）的code> NuGet 依赖项。For the project 3 I have installed a NuGet dependency of Microsoft.EntityFrameworkCore.Sqlite (2.0.3).现在，当我最终要使用项目 3 并调用它的方法时，将引发以下异常：Now, when I finally want to make use of project 3 and call it's method, the following exception is being thrown:System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.EntityFrameworkCore, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The system cannot find the file specified.这当然是丢失的DLL文件-没有实体框架DLL被复制到应用程序 Debug 目录。This, of course is a missing DLL file - no entity framework DLL's are being copied to the app Debug directory. 为什么？这是预期的行为吗？我是否还必须为项目 1 安装 Microsoft.EntityFrameworkCore.Sqlite 的依赖项？对于我而言，毫无意义，因为它引用了没有使用它的项目依赖项。Why is that? Is this intended behaviour? Do I have to install the dependency of Microsoft.EntityFrameworkCore.Sqlite for project 1 as well? Pretty pointless to me, referencing the same dependency to project that is making no use of it. 我尝试过什么： 清洁项目，删除bin / obj目录， 设置项目引用属性，将 copy local 设置为 True ， 此问题中给出的解决方案：引用的DLL无法复制到引用项目中Cleaning up the project, removing bin/obj directories,Set project reference properties setting copy local to True,Solutions given in this question: Referenced DLL not being copied to referencing project使用Visual Studio 2017。Using Visual Studio 2017.推荐答案通过在我的 .csproj 文件中添加以下行来解决此问题：Solved this by adding the following line into my .csproj file:<RestoreProjectStyle>PackageReference</RestoreProjectStyle>专门用于 PropertyGroup 组。不知道为什么会产生这种差异，如果有人可以解释并发表评论，那将是很棒的。我将添加到此答案中的所有其他信息。Not sure why it makes such difference, if anyone could explain and post in the comment it would be great. Any additional informations I will add to this answer. 这篇关于引用的项目依赖项DLL不被复制的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
