我一直在尝试发布我的应用程序，但我一直遇到错误:

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。

我以为我的项目可能有问题，但我按照以下步骤创建一个空白模板项目时遇到了完全相同的问题:

1 - Visual Studio 2015(更新 3 加上已安装的补丁)=> 文件 => 新建 => 项目 => ASP.NET Core Web 应用程序 (.NET Core) 和个人用户帐户

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:

我试图在 Nuget 中找到丢失的包，并尝试将其手动添加到 project.json，但都没有用。我错过了什么？

请您参考如下方法:

我真的没有在配置文件中看到 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，你必须有一个部分 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”部分下搜索 Microsoft.DotNet.ProjectModel。 - 注意:您需要选择预发布选项。

安装后您将能够看到它。

尝试发布到我的本地驱动器本身并顺利发布
