無法在框架 4.7.2 中恢復 nuget 包

[英]Cant restore nuget packages in framework 4.7.2

問題描述

我有一個 WPF 項目。 它有三個用 .Net Framework 4.7.2 編寫的庫。 我正在嘗試為此解決方案恢復 nuget 包，但我不能。

當我右鍵單擊sln文件，然后選擇Restore Nuget Packages一切似乎都正常：

但是在我運行程序后，它仍然缺少所有引用：

在每個csproj packagaes.config文件中都存在。 例如：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Autofac" version="5.0.0" targetFramework="net472" />
  <package id="Caliburn.Micro" version="4.0.62-alpha" targetFramework="net472" />
  <package id="Caliburn.Micro.Core" version="4.0.62-alpha" targetFramework="net472" />
  <package id="LiveCharts" version="0.9.7" targetFramework="net472" />
  <package id="LiveCharts.Wpf" version="0.9.7" targetFramework="net472" />
  <package id="MaterialDesignColors" version="1.2.0" targetFramework="net472" />
  <package id="MaterialDesignExtensions" version="2.7.0" targetFramework="net472" />
  <package id="MaterialDesignThemes" version="2.6.0" targetFramework="net472" />
  <package id="Microsoft.Bcl.AsyncInterfaces" version="1.1.0" targetFramework="net472" />
  <package id="Microsoft.Xaml.Behaviors.Wpf" version="1.0.1" targetFramework="net472" />
  <package id="System.Runtime.CompilerServices.Unsafe" version="4.5.2" targetFramework="net472" />
  <package id="System.Threading.Tasks.Extensions" version="4.5.2" targetFramework="net472" />
</packages>

我的問題是，如何從這個項目中恢復所有 nuget 包？ 我正在開發 Visual Studio 2019。

有兩種方法可以管理 nuget 包： Packages.config和PackageReference 。

根據您的圖片，我們可以看到您在項目中同時使用了這兩種格式，這是導致未知還原問題的原因。

在此處輸入圖片說明

（黃色表示 Packages.config，藍色表示 PackageReference 格式）

我們不應在一個項目中同時使用兩種格式，因此解決您的問題的方法是強制您的項目僅使用一種格式。 由於您的三個項目都使用 packages.config，您可以考慮刪除項目文件中的PackageReference定義。

解決方法：

編輯您的項目文件並刪除諸如<PackageReference Include="StyleCop.Analyzers">xxx</PackageReference>和<RestoreProjectStyle>PackageReference</RestoreProjectStyle>如果存在）。
