在ASP.Net核心中使用Entity Framework Core進行腳手架時出錯

我正在嘗試使用現有的SQL Server 2016數據庫創建模型。當運行命令提示符時，如文檔中所示：

PM> Scaffold-DbContext "'Server=techestatevm.southeastasia.cloudapp.azure.com;Database=Blogging;User Id=newuser;Password=pass;'" Microsoft.EntityFrameworkCore.SqlServer -verbose

我收到此錯誤：

工作目錄：E：\ Personal \ TE \ VS Projects \ EFGetStarted.AspNetCore.ExistingDb \ src \ EFGetStarted.AspNetCore.ExistingDb
執行命令：dotnet ef --configuration Debug --build-base-path。\ bin \ dbcontext scaffold''Server = techestatevm.southeastasia.cloudapp.azure.com; Database = Blogging; User Id = newuser; Password = pass;' “
Microsoft.EntityFrameworkCore.SqlServer --verbose
在行：1字符：215
+ ... user; Password = pass;''Microsoft.EntityFrameworkCore.SqlServer --verbo ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~表達式或語句中出現意外的標記'Microsoft.EntityFrameworkCore.SqlServer'。

我添加了所有Nuget包。看我的project.json ：
