Update() shouldn't load existing entity
Since EF5+ automatically attaches an entity whenever it is marked as modified, your code:
TObject existing = await _context.Set<TObject>().FindAsync(key);
if (existing != null)
{
_context.Entry(existing).CurrentValues.SetValues(updated);
await _context.SaveChangesAsync();
}should be updated to:
_context.Entry(updated).State = EntityState.Modified;
await _context.SaveChangesAsync();This gives three huge advantages:
a) only one database trip
b) less resource load, because no need for loading the original entity
c) no need for specifying a key, hence no concrete type dependence and a true generic method
Please see this StackOverflow comment for further details.
DataContext class missing methods
Hi,
DataContext class are missing lots of methods which are implemented in that BaseService class like Set method, SaveChangesAsync..
Am I missing any reference dll?
where are there?
Return IQueryable
I am curious why you decided to go with returning list objects vs IQueryables? Without the ability to retrieve IQueryable objects don't you limit access to linq extensions such as Include.
