在我的VS2013项目中参考:

• EntityFramework 6.1.3,
• EntityFramework.SqlServerCompact(对于SQLServerCompact 4.0)

我在edx文件中遇到错误.VisualStudio说:

Exception has been thrown by the target of an invocation

并且无法打开或更新edmx文件.

任何人都可以帮助解决这个问题？

这是app.config的摘录:

  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

    </sectionGroup>
  </configSections>
  <connectionStrings>
    <add name="ImirDBEntities" connectionString="metadata=res://*/ImirDB.csdl|res://*/ImirDB.ssdl|res://*/ImirDB.msl;provider=System.Data.SqlServerCe.4.0;provider connection string=&quot;Data Source=C:\ProgramData\Telesto\ImirDB.sdf&quot;"
      providerName="System.Data.EntityClient" />
  </connectionStrings> …

在.Net中是否有一个可以使用的结构,它包含两个整数(如Point)？
