Answer 1

I just spent half a day trying to get SqlServerCe 4.0 SP1 aka 4.0.0.1 to work without above exceptions. Finally solved, hope it'd help someone else.

1. Install SqlServerCe 4.0 SP1 either from here or via web platform installer

2. Copy "Program Files (x86)\Microsoft SQL Server Compact Edition\v4.0\Private" amd64 and x86 to bin folder of your web app and include them in project (so that they become deployable)

3. Do not copy "System.Data.SqlServerCe.dll" and "System.Data.SqlServerCe.Entity.dll"

4. nuget "Microsoft.SqlServer.Compact" was installed instead of obsolete "SqlServerCompact"
5. project references do not contain System.Data.SqlServerCe, however it would exist in bin folder after project clean/build procedure
6. web.config

answers above are valid BUT "Version=4.0.0.1" didn't work for me, instead just "4.0"
