sql compact membership provider error - asp.net-mvc-3

Question

For an ASP.NET MVC3 project, I decided to move from the standard SQL express membership provider to an SQL compact membership provider. I installed the microsoft universal provider nuget package (mentioned here: http://sqlcemembership.codeplex.com/).
This gave me the following error:
Unable to find the requested .Net Framework Data Provider. It may not be installed.
After googling it, I found that I had to add the following to my 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>
Which I did. I am now stuck with the following error that I cannot seem to get rid of:
Failed to find or load the registered .Net Framework Data Provider.
The error occurs when I try to access the membership database through the Membership class.
What am I doing wrong? I've posted my entire web.config file below.

Answer 1

The solution is that SQL Server Compact is not a native part of the .NET framework, but must be installed separately. This installer can be downloaded here: http://www.microsoft.com/en-us/download/details.aspx?id=17876
