c# - 无法发布 .NET Core Web 应用程序(无法加载文件或程序集 Microsoft.DotNet.ProjectModel)

Question

我一直在尝试发布我的应用程序，但总是遇到错误:

System.IO.FileNotFoundException:无法加载文件或程序集“Microsoft.DotNet.ProjectModel，Version=1.0.0.0，Culture=neutral，PublicKeyToken=adb9793829ddae60”。系统找不到指定的文件。

我认为我的项目可能有问题，但按照以下步骤创建空白模板项目，我遇到了完全相同的问题:

1 - Visual Studio 2015(已安装更新 3 和补丁)=> 文件 => 新建 => 项目 => 具有单独用户帐户的 ASP.NET Core Web 应用程序 (.NET Core)

2 - 右键单击​​项目 => 发布 => 选择我的 Azure 配置文件 => 单击发布

3 - 发布失败并出现上述错误

这是我的project.json:

  "scripts": {
    "prepublish": [ "bower install", "dotnet bundle" ],
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }

我尝试在 Nuget 中找到丢失的包，并尝试将其手动添加到 project.json，但都没有成功。我错过了什么？

Answer 1

真的，我在配置文件中没有看到 ProductModel。

您能否通过包管理器控制台尝试Install-Package Microsoft.DotNet.ProjectModel -Pre。或右键单击该项目并选择“管理 NuGet 包”并搜索 Microsoft.DotNet.ProjectModel 并安装它。

然后检查package.json，必须有一个部分Microsoft.DotNet.ProjectModel。

根据评论更新

尝试了以下步骤来显示。

1. 创建一个新的 .Net Core Web 应用程序。
2. 右键单击“引用”并选择“管理 NuGet 包”。
3. 在浏览部分中搜索 Microsoft.DotNet.ProjectModel。 - 注意:您需要选择预发布选项。

安装后您将能够看到这一点。

尝试发布到我的本地驱动器本身并发布，没有任何问题
