Question

I am working on a MVVM project using Entity Framework 5.0.

I connect to a hosted DB and sometimes Entity Framework looses connection to the DB.

What would be the best way to reconnect the connection to the DB when the connection was lost?

Answer 1

When connection is broken during saving your changes you simply get exception. Whole saving is done in transaction which is not committed due to the exception and EF doesn’t mark its current changes set as completed. You can simply try to save changes again when that specific exception happens – EF will try to open a new connection and execute the same transaction

for ex.:
well, maybe something like this:

public virtual void SubmitChanges()
{
    if (DataContext != null)
    {               
        try
        {
             DataContext.SubmitChanges();
        }
        catch (Exception whenILostMyConnection)
        {
             SubmitChanges(); //recall the sumbitChanges
        }
    }             
}
