每当我尝试运行 WebSecurity.InitializeDatabaseConnection() 时，它都会失败并出现错误

找不到请求的 .Net Framework 数据提供程序。它可能没有安装。

这是方法调用：

WebSecurity.InitializeDatabaseConnection("DataContext", "Users", "Id", "UserName", autoCreateTables: true);

这是我的数据库连接字符串（我在 MVC 应用程序中使用并且工作正常）：

<add name="DataContext" connectionString="metadata=res://*/Entities.DataModel.csdl|res://*/Entities.DataModel.ssdl|res://*/Entities.DataModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=(LocalDB)\v11.0;Initial Catalog=DBName;Integrated Security=True;MultipleActiveResultSets=True;Application Name=EntityFramework&quot;" providerName="System.Data.EntityClient" />

这是我的：

  <system.data>
    <DbProviderFactories>
      <remove invariant="System.Data.SqlServerCe.4.0" />
      <add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
      <remove invariant="System.Data.SqlClient" />
      <add name="SqlClient Data Provider"
       invariant="System.Data.SqlClient"
       description=".Net Framework Data Provider for SqlServer"
       type="System.Data.SqlClient.SqlClientFactory, System.Data,
     Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
    </DbProviderFactories>
  </system.data>

这是回调：

编辑：

在遵循 allo_man 的说明（排序——确切的代码不起作用，所以我在 MSDN 上查找了该类并使用了他们的示例）之后，我收到了一个新错误。“路径中有非法字符。”

  // Specify the provider name, server and database. 
  string providerName = "System.Data.SqlClient";
  string serverName = "(LocalDB)\v11.0";
  string databaseName = "aoeu";

  // Initialize the connection string builder for the 
  // underlying provider.
  SqlConnectionStringBuilder sqlBuilder = new SqlConnectionStringBuilder();

  // Set the properties for the data source.
  sqlBuilder.DataSource = serverName;
  sqlBuilder.InitialCatalog = databaseName;
  sqlBuilder.IntegratedSecurity = true;

  // Build the SqlConnection connection string. 
  string providerString = sqlBuilder.ToString();

  // Initialize the EntityConnectionStringBuilder.
  EntityConnectionStringBuilder entityBuilder =
      new EntityConnectionStringBuilder();

  //Set the provider name.
  entityBuilder.Provider = providerName;

  // Set the provider-specific connection string.
  entityBuilder.ProviderConnectionString = providerString;

  // Set the Metadata location.
  entityBuilder.Metadata = @"res://*/Entities.DataModel.csdl|
                    res://*/Entities.DataModel.ssdl|
                    res://*/Entities.DataModel.msl";

  //var builder = new EntityConnectionStringBuilder();
  //string sqlConnString = builder.ConnectionString;
  WebSecurity.InitializeDatabaseConnection(entityBuilder.ConnectionString, "Users", "Id", "UserName", autoCreateTables: true);

您不能将 EntityFramework 连接与 WebSecurity.InitializeDatabaseConnection 一起使用。如果您想拥有相同的连接字符串，您可以使用 EntityConnectionSTring Builder

var builder = new EntityConnectionStringBuilder(entityConnectionString);
string sqlConnString = builder.ConnectionString;

然后使用该连接字符串初始化 SimpleMembershipProvider

WebSecurity.InitializeDatabaseConnection(sqlConnString, "User", "UserId", "UserName", autoCreateTables: true);

在以前的 SQL CE 版本中，您必须同时安装 32 位和 64 位版本才能工作。检查您的 machine.config 文件，确认 SQL CE 数据提供程序已正确注册。

显然，Entity 不适用于此，即使使用建议的类 allo_man 也是如此。但是，如果我向使用 System.Data.SqlClient 的 Web.config 添加另一个连接字符串，然后将其与 InitializeDatabaseConnection() 一起使用，它就可以工作
