Entity Framework Timeouts

Entity Framework Timeouts

There is a known bug with specifying default command timeout within the EF connection string.

http://bugs.mysql.com/bug.php?id=56806

Remove the value from the connection string and set it on the data context object itself. This will work if you remove the conflicting value from the connection string.

Entity Framework Core 1.0:

this.context.Database.SetCommandTimeout(180);

Entity Framework 6:

this.context.Database.CommandTimeout = 180;

Entity Framework 5:

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

Entity Framework 4 and below:

this.context.CommandTimeout = 180;

Set database timeout in Entity Framework

Try this on your context:

public class MyDatabase : DbContext
{
    public MyDatabase ()
        : base(ContextHelper.CreateConnection("Connection string"), true)
    {
        ((IObjectContextAdapter)this).ObjectContext.CommandTimeout = 180; // seconds
    }
}

If you want to define the timeout in the connection string, use the Connection Timeout parameter like in the following connection string:

<connectionStrings>

<add name="AdventureWorksEntities"
connectionString="metadata=.\AdventureWorks.csdl|.\AdventureWorks.ssdl|.\AdventureWorks.msl;
provider=System.Data.SqlClient;provider connection string='Data Source=localhost;
Initial Catalog=AdventureWorks;Integrated Security=True;Connection Timeout=60;
multipleactiveresultsets=true'" providerName="System.Data.EntityClient" />

</connectionStrings>

How can I avoid TimeOut exception using Entity Framework with a stored procedure?

Entity Framework uses underlying connection provider and depends on the timeout provided by the provider. Usually its 30 seconds for the timeout if I am not mistaken.

However you can always increase the timeout by setting value of context.CommandTimeout = 120 in seconds

Hope this helps.

How to set command timeout in aspnetcore/entityframeworkcore

If you're using the DI container to manage the DbContext (i.e. you're adding the DbContext to the service collection), the command timeout can be specified in the options.

In Startup.ConfigureServices:

services.AddDbContext<YourDbContext>(options => options.UseSqlServer(
    this.Configuration.GetConnectionString("YourConnectionString"),
    sqlServerOptions => sqlServerOptions.CommandTimeout(60))
);

Set Command Timeout in EF 6

Check this :

Entity Framework 6 :

this.context.Database.CommandTimeout = 180;

Entity Framework 5:

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

Entity Framework 4 and below:

this.context.CommandTimeout = 180;
