SQLite in .Net

After using SQLite for a while, a few conclusions that I had were

1. SQLite is quite stable enough to be used in corporate environment.
2. SQLite is faster than SQLCE.
3. For a SQLite admin, use the Firefox addon -  https://addons.mozilla.org/de/firefox/addon/sqlite-manager/
4. SQL Server Compact Toolbox will be useful: https://visualstudiogallery.msdn.microsoft.com/0e313dfd-be80-4afb-b5e9-6e74d369f7a1
5. Both SQLite and SQLCE cannot be used in a condition that requires to write in DB concurrently. To make sure that an application does not access the DB concurrently, 'lock' statement was used.
6. Both can be used with Entity Framework, which is nice.

Installation is relatively easy, but set up could be confused as some of tutorial does not work as it should be due to the version difference (?) and NuGet didn't properly updated config file in my case, so I had to update it manually. I've current set up both SQLite and SQLCE with the versions as below. Entity Environment 6.0 Data.Dqlite.EF6 1.0.98.0 System.Data.SqlServerCe 4.0 Below is the configuration for SQLite and SQLCE to be used together.
