我用 project.json
导入 EntityFramework 6.1.3
NuGet 包。我可以确认 NuGet 包已在我的函数应用中成功还原。
根据document ,我可以直接使用EntityFramework。但是,我不断收到错误消息,例如:
ManualTriggerCSharp1: Could not load file or assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.
EntityFramework.dll
和
EntityFramework.SqlServer.dll
进
bin
目录,它仍然提示同样的异常。
project.json
文件:

"dependencies": {
"Autofac": "4.2.0",
"AutoMapper": "5.1.1",
"EntityFramework": "6.1.3",
"Newtonsoft.Json": "9.0.1"
}
}
}
}
EntityFramework.dll
和
EntityFramework.SqlServer.dll
进
bin
目录并在
run.csx
中引用它文件如:
#r "EntityFramework.dll"

以下步骤适用于最新的 Functions 运行时 (1.0)。创建一个新函数(例如 ManualTrigger),并使用“查看文件”UI 添加一个新的 project.json
包含以下内容的文件:
{
"frameworks": {
"net46":{
"dependencies": {
"EntityFramework": "6.1.3"
}
}
}
}
