我已将我在 EF 4.0 中的项目更新为 EF 4.3.1。但是，当我创建一个新的 Context 对象时，会引发异常：

Culture is not supported.
Parameter name: name
2.3.2 is an invalid culture identifier.

完整的堆栈跟踪：

我不知道这个问题...

我会很高兴有任何帮助。

提前致谢

看起来您的一个程序集的文化不正确。出于性能原因，默认情况下，Entity Framework 会过滤掉很可能没有实体的程序集，例如属于 .NET Framework 的程序集或 Microsoft 提供的程序集。实体框架正在使用公钥令牌来过滤掉这些程序集。要获取公钥令牌，AssemblyName 对象是使用 assembly.FullName 创建的。如果 assembly.FullName 不是有效的程序集名称，您将看到上述异常。
