When should I create a new DbContext()

Question

I am currently using a DbContext similar to this:

namespace Models
{
    public class ContextDB: DbContext
    {

        public DbSet

This is obviously an older question but if your using DI you can do something like this and scope all your objects for the lifetime of the request

 public class UnitOfWorkAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            var context = IoC.CurrentNestedContainer.GetInstance();
            context.BeginTransaction();
        }

        public override void OnActionExecuted(HttpActionExecutedContext actionContext)
        {
            var context = IoC.CurrentNestedContainer.GetInstance();
            context.CloseTransaction(actionContext.Exception);
        }
    }
