sql compact会员提供程序错误

Question

对于ASP.NET MVC3项目，我决定从标准SQL Express成员资格提供程序移至SQL compact会员提供程序。我安装了微软通用提供程序nuget包（这里提到：http://sqlcemembership.codeplex.com/）。

这给了我以下错误：

Unable to find the requested .Net Framework Data Provider. It may not be installed. 

谷歌搜索之后，我发现，我不得不以下内容添加到我的web.config：

<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" /> 
    </DbProviderFactories> 
</system.data> 

，我做到了。我现在坚持了以下错误，我似乎无法摆脱的：当我尝试通过Membership类来访问会员数据库发生

Failed to find or load the registered .Net Framework Data Provider. 

错误。 我在做什么错？我在下面发布了我的整个web.config文件。

解决方法是SQL Server Compact不是.NET框架的本地部分，但必须单独安装。这个安装程序可以在这里下载：http://www.microsoft.com/en-us/download/details.aspx?id=17876
