推荐答案

发生在 EF5 RTM，VS2012 RTM 中。

今天的问题。我在PM控制台中执行了更新包EntityFramework。 NuGet没有报告任何更改，问题仍然存在。然后，我重新启动了VS2012，并重新尝试了Update-Database，它按预期工作。目前尚不清楚是什么导致了此问题，也不清楚Update-Package是否有助于纠正此问题。

I experienced this problem today. I executed "Update-Package EntityFramework" in the PM Console. No changes were reported by NuGet and the problem persisted. I then restarted VS2012 and re-attempted Update-Database and it worked as expected. It's not clear what caused this problem, it's also not clear whether the Update-Package contributed to correcting it or not.

首先尝试重新启动Visual Studio，然后尝试执行Update-Package EntityFramework，然后重新启动。

First try restarting Visual Studio, then try Update-Package EntityFramework followed by a restart.
