Entity Framework Object Context per request in ASP.NET? [closed]

Answer 1

Yes it is an accepted approach to have ObjectContext/DbContext with lifetimes per HttpRequest. Here's a sample I have provided in another answer.

Hoewever, it's better to leave these lifetime managements to an IoC library. Famous ones are Castle Windsor, Autofac.

Update:
To dispose your context, you can use Application_EndRequest method in Global.asax. The following code is not tested but you'll get the idea:

protected virtual void Application_EndRequest()
{
    var key = "MyDb_" + HttpContext.Current.GetHashCode().ToString("x")
                      + Thread.CurrentContext.ContextID.ToString();
    var context = HttpContext.Current.Items[key] as MyDbContext;

    if (context != null)
    {
        context.Dispose();
    }
}
