c# - EF 4, how to add partial classes -

i needed extend ef partial classes, because want add functionality able use oracle's sequences , don't know how use partial class thing, made seperate .cs file , name 1 of auto-generated classes follows:

namespace glassstoredal {     public partial class car      {         private int _sequences;         public int sequences         {             { return _sequences; }             set { _sequences = value; }         }     }   } 

now assumed that, on bll - references glassstoredal - can find "sequences" property , apparently goes wrong, appreciate here.

here generated partial class , should have sequences property there?

to summarise large comment trail...

check partials being attached correctly:

• make sure both class definitions in same namespace , assembly.
• make sure @ least 1 of them declared partial (most generated classes are, including ef generated ones).
• check make sure newly created partial can see previous members, confirm partials match up.

where client in different binary (which case here)

• make sure client projects binary/references date (perform clean build / delete binary copy / recreate reference), depending upon project situation.

for case, last check important , solved problem.
