title: How can I connect to a SQL Server Compact 3.5 file as a data source in Visual Studio 2012?
body: <p>Visual Studio 2012 comes with SQL Server Compact 4.0. I have installed SQL Server Compact 3.5 from <a href="http://www.microsoft.com/en-GB/download/confirmation.aspx?id=5783" rel="nofollow noreferrer">http://www.microsoft.com/en-GB/download/confirmation.aspx?id=5783</a> However I still only have the option of making a new data connection to a SQL Server Compact 4.0 file, whereas the files I need to get data from are SQL Server Compact 3.5 files.</p>

  <p>Is it possible to connect to a SQL Server Compact 3.5 file as a data source in Visual Studio 2012? If so which settings or installs should I need?</p>
