MSB4018 错误 - 解决包依赖关系和解决包资产任务意外失败 .net5 - Visual Studio 22

Question

我有一个 .net5 项目，我需要调试该项目使用的库。为此，我卸载了库的 NuGet 包并将项目引用添加到我的项目中。现在，我无法构建该项目。构建后我收到以下错误：

The "ResolvePackageDependencies" task failed unexpectedly.
System.ArgumentException: An item with the same key has already been added.

和

csproj 中没有重复的包。我该如何解决这个问题？我已经尝试过：

• 删除 bin、obj 和 .vs 文件夹
• 恢复 Nuget 包
• 清除所有 NuGet 缓存

谢谢。

Answer 1

我找到了解决方案。问题是另一个解决方案项目仍然引用 NuGet 包而不是本地项目。因此，删除依赖项并添加对本地包的引用就足够了。
