If I install SQL Server CE 4.0, will apps targeting 3.5 continue to work?

If I install SQL Server CE 4.0, will this have any effect on projects that use SQL Server CE 3.5? I just want to make sure 3.5 won't get written over or become unusable.

Some context for this question: I currently have a couple projects in the works that use LinqToSql (SqlMetal) and SQL Server CE 3.5.开发者_开发技巧 I want to make sure these projects will continue to work while I download and experiment with all the "new stuff"--Visual Studio 2010 SP1 beta, .NET 4.0 Update beta, Entity Framework 4 Code First CTP5, and SQL Server CE 4.0.

3.0, 3.5 and 4.0 can all be installed side-by-side, but SQL Server Compact 4.0 does not support SqlMetal, you must use Entity Framework instead.
