Windsor and DbContext per request - DbContext has been disposed

castle-windsor, dbcontext, entity-framework

Solution

You are registering `ISomeService` with the default lifecycle, which is singleton. Once it's created, it will keep using the same DbContext. Simplest solution is to change its lifecycle to per request or transient.

container.Register(Component.For<ISomeService>()
                            .ImplementedBy<SomeService>()
                            .LifeStyle.PerWebRequest);

Problem

I have a method in HomeController, that I'm trying to access through URL, like this: ``` http://localhost/web/home/GetSmth ``` First time it works, but after refreshing page, I get this error: ``` The operation cannot be completed because the DbContext has been disposed. ``` As the title states, I'm trying to use Castle Windsor and DbContext per request. ``` public class Installer1 : IWindsorInstaller { public void Install(IWindsorContainer container, IConfigurationStore store) { container.Register(Classes.FromThisAssembly() .BasedOn<IController>() .LifestyleTransient() ); var connString = ConfigurationManager.ConnectionStrings["MainDbContext"].ConnectionString; container.Register(Component.For<MainDbContext>().DependsOn(Property.ForKey("conn").Eq(connString)).LifeStyle.PerWebRequest); container.Register(Component.For<ISomeService>().ImplementedBy<SomeService>()); } } ``` HomeController looks like this: ``` public class HomeController : Controller { private ISomeService _someService; public HomeController(ISomeService someService) { _someService = someService; } public ActionResult Index() { return View(); } public JsonResult GetSmth() { var data = _someService.GetData().ToList(); return Json(data, JsonRequestBehavior.AllowGet); } } ```
