c# - EntityFramework 6 Connection Closed -

i did upgrade ef 6 , when query showing error:

executereader requires open , available connection. connection's current state closed.

code:

var db = new entity2entities(); db.configuration.lazyloadingenabled = true;  var ids = db.personbase.sqlquery(utils.query(param, "personbase"))                        .select(x => x.id); var result = db.employee.where(x => ids.contains(x.id)); 

ef 6 in alpha state, things can change in future. didnt try maybe have do

db.database.connection.open(); 

before executing sqlquery method.
