visual-studio-2012 - ORACLE Database First EF4 to EF5 in VS2K12: error 0040: The Type XXX is notqualified with a namespace or alias

Question

我有VS2K12一个.edmx file使用dotConnect 7.2.96.0. 我有一些uTests像魅力一样对抗数据库的东西。

如果我更改Entity Framework（从版本 4 到 5）的版本并将项目更新为Framework 4.5，则解决方案会编译，但uTests每当他们尝试获取数据库的上下文时，都会失败并出现以下错误：

`System.Data.MetadataException was unhandled by user code
  HResult=-2146232007
  Message=Schema specified is not valid. Errors: 

AlertingData.ssdl(54,6) : error 0040: The Type NVARCHAR2 is not qualified with a namespace or alias. Only primitive types can be used without qualification.

AlertingData.ssdl(57,6) : error 0040: The Type TIMESTAMP WITH LOCAL TIME ZONE is not qualified with a namespace or alias. Only primitive types can be used without qualification.

其中几个。欢迎任何帮助。

Answer 1

请在第一次使用上下文之前设置“ColumnTypeCasingConventionCompatibility = false”（例如：在部分类的静态构造函数中）或在 *.config 中：

<configuration>
  <configSections>
    <section name="Devart.Data.Oracle.Entity" type="Devart.Data.Oracle.Entity.Configuration.OracleEntityProviderConfigurationSection,
      Devart.Data.Oracle.Entity, Version=7.2.96.0, Culture=neutral,
      PublicKeyToken=09af7300eec23701" />
  </configSections>
  <Devart.Data.Oracle.Entity xmlns="http://devart.com/schemas/Devart.Data.Oracle.Entity/1.0">
    <CodeFirstOptions ColumnTypeCasingConventionCompatibility="false"/>
  </Devart.Data.Oracle.Entity>
</configuration>
