SQL Server CE database not Affected for insert and update

Question

I am writing C# Forms application and using normal SQL Server CE database ( .sdf ).

What happened is that no changes are written to the database. For example when trying to add a row, it will never show up in the database table. But when do the selection, it seems that it does exist !

What is the problem here ?

Answer 1

When you use |DataDirectory| or simply a relative path then you have 2 copies of the SDF file in your project folders.

Your application is using the one in ..\\Root\\bin\\debug .

Your tools (VS server explorer) are looking in ..\\Root .
