c# - SQL Server CE Incompatible Database Version -


i have sql server ce 4.0 database (.sdf file) , when trying doing query on database application (wpf) following error.

incompatible database version. if compatible file, run repair. other cases refer documentation. [ db version = 4000000,requested version = 3505053,file name = \?\c:\database\shortagereport\mrpdatabase.sdf]

  • i have checked sql server ce 4 sp1 installed.
  • i have tried creating database in both database.net 4 , in connection setup in vs2012.
  • i'm running windows 7 64bit
  • my connection string stored in app.config.

i using sql server compact toolbox generate context , mappings.

my app.config:

<connectionstrings>     <add name="databasecontext"           providername="system.data.sqlserverce.4.0"           connectionstring="data source=c:\database\shortagereport\mrpdatabase.sdf"/> </connectionstrings>

any ideas?

add reference version 4.0 system.data.sqlserverce.dll ado.net provider

then initialize datacontext class sqlceconnection (4.0) object.

using (sqlceconnection conn = new sqlceconnection(@"data source=c:\projects\chinook\chinook40.sdf")) {     using (chinook db = new chinook(conn))     {         var list = db.album.tolist();         if (list.count > 0)             system.diagnostics.debug.print("it works!");     } }
