wpf - SQL server CE 4.0 windows XP -


i have made wpf application works fine on windows7 , xp. however, after adding functionality related databases , entity framework still runs under windows 7 not on windows xp. every time tries use database "operation not supported on platform".

i have added dlls needed , modified .config can see app can run without sql server ce 4.0 installed. have tried installing sql ce on windows xp machine , edit .config use instead of dlls, same result.

more info: app made run on .net framework 4.0

should try embedded db? 

<configuration>   <configsections>     <!-- more information on entity framework configuration, visit http://go.microsoft.com/fwlink/?linkid=237468 -->     <section name="entityframework" type="system.data.entity.internal.configfile.entityframeworksection, entityframework, version=4.4.0.0, culture=neutral, publickeytoken=b77a5c561934e089" requirepermission="false" />   </configsections>   <system.data>     <dbproviderfactories>       <remove invariant="system.data.sqlserverce.4.0"/>       <add name="microsoft sql server compact data provider 4.0" invariant="system.data.sqlserverce.4.0" description=".net framework data provider microsoft sql server compact" type="system.data.sqlserverce.sqlceproviderfactory, system.data.sqlserverce, version=4.0.0.1, culture=neutral, publickeytoken=89845dcd8080cc91"/>     </dbproviderfactories>   </system.data>   <connectionstrings>     <add name="conexion" connectionstring="data source=|datadirectory|database.sdf" providername="system.data.sqlserverce.4.0" />    </connectionstrings>   <entityframework>     <defaultconnectionfactory type="system.data.entity.infrastructure.localdbconnectionfactory, entityframework">       <parameters>         <parameter value="v11.0" />       </parameters>     </defaultconnectionfactory>   </entityframework> </configuration>

ok found problem. seems sql server ce 4.0 needs windows xp sp3, , test machine had sp2, shame on me!
