Set database timeout in Entity Framework

My partial context looks like:

public partial class MyContext : DbContext
{
    public MyContext (string ConnectionString)
        : base(ConnectionString)
    {
        this.SetCommandTimeOut(300);
    }

    public void SetCommandTimeOut(int Timeout)
    {
        var objectContext = (this as IObjectContextAdapter).ObjectContext;
        objectContext.CommandTimeout = Timeout;
    }
}

I left SetCommandTimeOut public so only the routines I need to take a long time (more than 5 minutes) I modify instead of a global timeout.

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>

In the generated constructor code it should call OnContextCreated()

I added this partial class to solve the problem:

partial class MyContext: ObjectContext
{
    partial void OnContextCreated()
    {
        this.CommandTimeout = 300;
    }
}

You can use DbContext.Database.CommandTimeout = 180; // seconds

It's pretty simple and no cast required.
