OK, this is the second request I hear for this, let us do it. I will fork the code, and make a Nuget package for 3.5 - how about "EntityFramework.SqlServerCompact.Legacy" ? The "only" code change required is the fact, that 3.5 does not support ORDER BY..FETCH..OFFSET syntax (ie paging) called via Take and Skip. Would you be interested in this?
UPDATE: Package now available on NuGet http://www.nuget.org/packages/EntityFramework.SqlServerCompact.Legacy
