Set Command Timeout in entity framework 4.3

Question

I cannot find the a way to set the command timeout of a linq query using entity framework 4.3 and its' DbContext. How do I increase Commandtimeout in entity framework?

EDIT I am actually looking for Command Timeout increase. I confused the two, it is the sql command that is timing out not the connection.

Thanks

Answer 1

If you're using DbContext, you'll first need to drop down to ObjectContext:

((IObjectContextAdapter)context).ObjectContext.CommandTimeout = 180;

Answer 2

I added the command timeout value in my Context class in an attempt to handle longer processing times for some of the stored procedures that are populating my application. Seems to have done the trick.

public partial class ExampleEntities : DbContext
    {
        public ExampleEntities()
            : base("name=ExampleEntities")
        {
            ((IObjectContextAdapter)this).ObjectContext.CommandTimeout = 180;
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }

Answer 3

this command is enough.

((System.Data.Entity.Infrastructure.IObjectContextAdapter) context).ObjectContext.CommandTimeout
                = 180;

Answer 4

I had problem with setting CommandTimeout when I use await, like this:

await _dbContext.Database.Connection.QueryAsync("Update ...."),

then I found in documentation https://docs.microsoft.com/en-us/dotnet/api/system.data.sqlclient.sqlcommand.commandtimeout?view=netframework-4.8 that:

The CommandTimeout property will be ignored during asynchronous method calls such as BeginExecuteReader.

I changed to:

_dataWarehouseDbContext.Database.Connection.Query("Update ...")

and CommandTimeout start working :)
