Metoda marcata cu abstract si override

O metoda sau o propietate poate sa fie marcata ca abstracta cand aceasta nu contine si implementarea.
O metoda sau o propietate poate sa fie marcata ca override cand vrem sa modificam implementarea si sa oferim o noua implementare pentru un menbru mostenit din clasa de baza.
Pana aici nimic deosebit, OOP pur. Oare putem sa avem o metoda care sa fie marcata atat abstracta cat si override? Raspunsul este DA. Desi pare ciudat, putem sa marcam o metoda cu aceste doua atribute:
public void abstract override DoWork();
Cand putem sa avem acest caz?
Cand avem o clasa abstracta care contine o metoda virtuala.
public abstract Actiune
public virtual void DoWork()
Aceasta clasa poate sa fie mostenita de o alta clasa care sa ofere o alta implementare de baza la metoda DoWork.
public abstract Actiune2 : Actiune
public abstract override void DoWork();
Orice clasa ce va implementa clasa abstracta Actiune2 o sa fie obligata sa ofere o implementare la metoda DoWork(), chiar daca Actiune2 mosteneste din clasa abstracta Actiune1 care ofera o implementare pentru metoda noastra.


  1. Aha - si la properties pot exista astfel de cazuri, desi arata ciudat:

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

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…
