实体框架7错误：＆QUOT; EntityFramework.Core.resources＆QUOT;缺少（7.0.0-RC1决赛）

问题描述

[解决]参见我的答案

我有一个项目，ASP.NET 5 EF7运行。

我有我的EF模型，类库，框架4.5.1。当我尝试与数据交互，我有这样的例外：文件EntityFramework.Core.resources丢失。但是，当我把EF模型在我的UI项目，它工作正常。
任何想法是怎么回事？是否有可能有一个专门的类库中的实体框架模型？ （我一直这样做的方式，但也许它已经与这个版本的变化）

这是类库包含了谁我EF7的的DbContext的package.config的内容：

我终于找到了，它是相对于这个问题：

这是一个DNX错误，但同时，我们等待一个修补程序，您可以添加到您启动的配置方法：

 公共无效配置（IApplicationBuilder应用程序，IHostingEnvironment ENV，ILoggerFactory的LoggerFactory）
{
    // ...
    VAR localizationOptions =新RequestLocalizationOptions（）
    {
        SupportedCultures =新的List＆LT;＆的CultureInfo GT; {新的CultureInfo（）}，
        SupportedUICultures =新的List＆LT;＆的CultureInfo GT; {新的CultureInfo（）}
    };    VAR InvariantCulture的=新RequestCulture（新的CultureInfo（），新的CultureInfo（））;    app.UseRequestLocalization（localizationOptions，InvariantCulture的）;
    // ...
}
 

[SOLVED] see my answer

I have a project running with ASP.NET 5 and EF7.

I have my EF model in a class library, framework 4.5.1. When I try to interact with data, I have this exception : the file "EntityFramework.Core.resources" is missing. But when I put the EF model in my UI project, it works fine.Any idea what's going on ? Is it possible to have the entity framework model in a dedicated class library ? (I always did this way but maybe it has changed with this version)

This is the package.config's content of the class library who contains my EF7's DbContext :

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework.Commands" version="7.0.0-rc1-final" targetFramework="net451" />

解决方案

I finally found, it's relative to this issues : - https://github.com/aspnet/dnx/issues/3047 - https://github.com/aspnet/EntityFramework/issues/4422

It's a dnx bug but while we waiting for a fix, you can add this to your Startup's Configure method :

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    //...
    var localizationOptions = new RequestLocalizationOptions()
    {
        SupportedCultures = new List<CultureInfo> { new CultureInfo("") },
        SupportedUICultures = new List<CultureInfo> { new CultureInfo("") }
    };

    var invariantCulture = new RequestCulture(new CultureInfo(""), new CultureInfo(""));

    app.UseRequestLocalization(localizationOptions, invariantCulture);
    //...
}
