Is there any way to modify the connection settings (e.g. set ARITHABORT on)

When EF talks to the SQL server, it sets the following settings with the “Audit Login” event (visible in SQL Server Profiler):

-- network protocol: LPC
set quoted_identifier on
set arithabort off
set numeric_roundabort off
set ansi_warnings on
set ansi_padding on
set ansi_nulls on
set concat_null_yields_null on
set cursor_close_on_commit off
set implicit_transactions off
set language us_english
set dateformat mdy
set datefirst 7
set transaction isolation level read committed

Is there any way to modify these settings before executing a query? In my case, I would like to enable ARITHABORT, since I am using a (apparently broken) stored procedure and with the setting being turned off, I just get a timeout because it never completes.

I tried doing a db.Database.ExecuteSqlCommand("SET ARITHABORT ON;"); before the query but EF resets the connection automatically afterwards restoring its settings.

EF isn’t explicitly sending this, it’s the underlying SQL Client ADO.NET provider that sets all these transparently to the caller. One option would be to create your DbConnection externally and then pass it to your context.

@dark2201 You’re probably better off asking in https://github.com/dotnet/corefx (which is where SQLClient lives) or on Stack Overflow.
