出版導致FileNotFoundException異常：無法加載文件或程序集「Microsoft.DotNet.ProjectModel」

Question

我得到一個錯誤，運行dotnet publish時：

dotnet restore 
dotnet build 
dotnet publish --configuration Release --runtime active 

的發佈是成功的，但我認爲這是有麻煩IISIntergration /修改web.config部分。

錯誤：

Configuring the following project for use with IIS: 'C:\Users\john-luke.laue\repositories\MyApp\src\MyApp\bin\Release\net461\active\publish' 
Could not load file or assembly 'Microsoft.DotNet.ProjectModel, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

如何調試或解決這個問題？

Answer 1

This github問題包含解決方案。你需要清除的NuGet高速緩存和恢復包（見this評論）：

1. 刪除%USERPROFILE%\.nuget\packages\.tools\Microsoft.EntityFrameworkCore.Tools和%USERPROFILE%\.nuget\packages\Microsoft.EntityFrameworkCore.Tools

2. 確保你的 「工具」 部分匹配這個：

   "tools": { 
       "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final" 
   } 
   

3. 回覆運行dotnet restore
