How to manualy set the location from where a controller is loaded

Uneori ajungem ca unul sau mai multe controale sa fie definite intr-un assembly diferit fata de proiectul MVC 3 pe care il avem. Pentru a putea controla mecanismul de incarcare a controalelor este nevoie sa ne definim propiul nostru controller factory.
Trebuie sa ne definim o clasa care sa implementeze interfata IControllerFactory. In cazul in care vrem sa pastram si vechia functionalitate care exista by default putem sa implementam clasa DefaultControllerFactory si sa facem override la CreateController. Aceasta metoda primeste doi parametrii
  • requestContext - care contine date despre request
  • controllerName - numele la controller
In interiorul acestei metode pe baza numelui la controler si a contextului trebuie sa returnam instanta controlerului nostru.

public class MyControllerFactory : DefaultControllerFactory
        public override IController CreateController(
System.Web.Routing.RequestContext requestContext,                                                      stringcontrollerName)         {             return Activator.CreateInstance(
customNamespaceController+controllerName);         }     }


  1. Portable areas din MVCContrib sunt promitator in sensul asta (, desi merita doar la proiecte complexe..

  2. Multumesc de link. O sa ma uit mai in detaliu in seara aceasta.

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

TeamCity.NET 4.51EF 6.0.2VS2013

Entity Framework (EF) TransactionScope vs Database.BeginTransaction

In today blog post we will talk a little about a new feature that is available on EF6+ related to Transactions.
Until now, when we had to use transaction we used ‘TransactionScope’. It works great and I would say that is something that is now in our blood.
using (var scope = new TransactionScope(TransactionScopeOption.Required)) { using (SqlConnection conn = new SqlConnection("...")) { conn.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = conn; sqlCommand.CommandText = ... sqlCommand.ExecuteNonQuery(); ... } scope.Complete(); } Starting with EF6.0 we have a new way to work with transactions. The new approach is based on Database.BeginTransaction(), Database.Rollback(), Database.Commit(). Yes, no more TransactionScope.
In the followi…

GET call of REST API that contains '/'-slash character in the value of a parameter

Let’s assume that we have the following scenario: I have a public HTTP endpoint and I need to post some content using GET command. One of the parameters contains special characters like “\” and “/”. If the endpoint is an ApiController than you may have problems if you encode the parameter using the http encoder.
using (var httpClient = new HttpClient()) { httpClient.BaseAddress = baseUrl; Task<HttpResponseMessage> response = httpClient.GetAsync(string.Format("api/foo/{0}", "qwert/qwerqwer"))); response.Wait(); response.Result.EnsureSuccessStatusCode(); } One possible solution would be to encode the query parameter using UrlTokenEncode method of HttpServerUtility class and GetBytes method ofUTF8. In this way you would get the array of bytes of the parameter and encode them as a url token.
The following code show to you how you could write the encode and decode methods.
