通过Package Manager Console 向VS2010安装 EntityFramework

尝试用VS2010--工具--Library Package Manager--Add Library Package Reference的online搜索 EntityFramework,

再找到的结果中,点选该Package的Install,

却提示错误:

"This package (or one of its dependencies) contains powershell scripts and needs to be installed from the package manager console."

 

根据提示改用Package Manager Console来安装,

打开VS2010--工具--Library Package Manager--Package Manager Console,

PM > get-package -remote -filter entityframework
