我还拥有所有nuget软件包的最新版本，包括System.ValueTuple和Npgsql

我按照本文中的步骤为我的应用程序创建了setup.exe，我不知道问题出在哪里

请帮帮我，谢谢

编辑：额外信息：我没有使用MVVM

编辑：添加有关如何制作SETUP.EXE的步骤
步骤1：我在解决方案中添加了一个安装项目
步骤2：我有以下文件夹

步骤3：我在前两个文件夹中添加了以下内容

到目前为止，我有以下几点：

步骤4：我在ProgramFiles文件夹中创建了一个文件的快捷方式，并将其添加到用户桌面和用户程序菜单的文件夹中

步骤5：我为所有文件夹将AlwaysCreate属性值设置为True

步骤6：我现在做的是重建解决方案并重建安装项目，然后我转到安装项目的调试文件夹并从setup.msi安装应用程序

您的csproj文件的目标是.NET Framework v 4.8，它已经嵌入System.ValueTuple。我怀疑烘焙版本和作为Nuget包添加的版本之间存在冲突

只需删除
系统的包引用。ValueTuple
（删除Nuget包）并重新构建就可以了，代码中可能有一些“正在使用”的引用也需要删除。
这似乎是解决问题的一个很长的方法，但取决于Dean所说的，您应该尝试创建一个新项目，并将目标framework设置为.Net framework 4.6.1，然后将所有文件从旧项目复制到新项目，然后重新尝试所有操作

希望这能解决您的问题。
您需要包括有关如何添加程序集的特定详细信息，因为您的操作不正确，而这正是造成问题的原因。一步一步地看你是如何做到的，这将有助于我们指出你在这一步上犯了错误。还可以编辑您的问题，以包含您的
.csproj
file@ScottChamberlain好的，我马上就发now@ScottChamberlain我补充了你的问题不确定你的问题是什么。csproj在我看来很好。我看不到会导致您收到错误的正常情况。我尝试删除该软件包，但它仍然不起作用，谢谢您的回答
