运行“无法找到或加载已注册的 .Net Framework 数据提供程序”时出现服务器错误。我将 Sql Compact 4 数据库包含在 ASP.NET MVC 4 + Entity Framework 中，上传到 godaddy 服务器... web.config 如下

使用 OP 的评论，我有一个稍微详细一点的版本。

有了nuget，就可以运行命令了

install EntityFramework.SqlServerCompact

下载 SqlServerCompact 当我尝试这样做时，我看到 3 个依赖项随之而来，因此您总共获得 4 个安装：

  • Microsoft.SqlServer.Compact
  • SqlServerCompact
  • 实体框架
  • EntityFramework.SqlServerCompacy

因此可以推断，遇到此问题的一个可能原因是您的安装缺少 SqlServerCompact。

我在一个简单的测试应用程序中遇到了类似的问题。

Install-PackageEntityFramework.SqlServerCompact通过将 SqlServer Compact dll 添加到应用程序“packages”目录中消除了“无法找到或加载已注册的 .Net Framework 数据提供程序”的消息。它在 packages.config 中添加了以下内容；

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="5.0.0" targetFramework="net40-Client" />
  <package id="EntityFramework.SqlServerCompact" version="4.3.6" targetFramework="net40-Client" />
  <package id="Microsoft.SqlServer.Compact" version="4.0.8876.1" targetFramework="net40-Client" />
  <package id="SqlServerCompact" version="4.0.8854.1" targetFramework="net40-Client" />
</packages>

它还添加了System.Data.SqlServerCe和System.DataSqlServerCe.Entity应用程序引用。

然后我遇到了这样的异常；

System.IO.FileLoadException was unhandled
  Message=Could not load file or assembly 'System.Data.SqlServerCe, Version=4.0.0.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

这似乎表明应用程序配置为使用 SqlServerCE v4.0.0.1 - 但发现 v4.0.0.0

所以我使用了 Eriks 的建议并将 DbProviderFactories 条目更改为 v4.0.0.0 并删除了引用 v4.0.0.1 新版本的 bindingRedirect 条目。

这似乎有效。希望它可以帮助任何走这条路的人......

与此同时，我有点困惑；

  1. 为什么System.Data.SqlServerCe.dllat 版本是 4.0.8876.1 - 我怎么知道这实际上是 v4.0.0.0
  2. v4.0.0.1 参考来自哪里 - 我必须在我的机器上安装这个版本？
