Intalnire RONUA: 2 martie 2011

Comunitatea RONUA din Cluj-Napoca a ajuns la a doua intalnire in acest format. Cei care doresc sa participle ii rog sa imi dea un reply la acest email pentru a putea sa stim la cate personae sa ne asteptam. Va asteptam.
Oricine e interesat in a afla si discuta subiecte interesante din lumea .NET si nu numai, e asteptat in data de 02 martie (miercuri), de la orele 19:00, la urmatoarea intalnire RONUA Cluj.

In urma votului, au ramas doua subiecte:
• ESB (enterprise service buss) - un mecanism prin care mai multe module (aplicatii) pot comunica intre ele, trimitand un fel de notificari http://en.wikipedia.org/wiki/Enterprise_service_bus (Radu Vunvulea)
• Customizable (desktop) applications design (DragoČ™ Andronic)
* se da un produs (desktop, windows, .net)
* 80% din functionalitate este ok pentru toti clientii insa fiecare client vrea altceva de la restul de 20% (adica doreste ca aplicatia sa ii fie customizata conform propriilor nevoi)
* ca sa realizam asta va voi prezenta 2 idei arhitecturale (exemplificate cu cod) prin care:
o deschidem spre customizare "main application workflow-ul" prin "pre action hooks" si "post action hooks". Tot legat de acest subiect voi prezenta si un model de organizare a codului (layere si assembliuri) pentru a usura astfel de customizari
o permitem clientului sa customizeze structura de meniuri a aplicatiei (main menu, toolbar menus. context menus): componenta meniurilor, aspectul lor, functionalitatea lor
(durata: ~ 1h)
Fiecare prezentare va fi urmata (daca se doreste) de discutii libere pe marginea subiectului.
Locatia: Evoline, Sigma Tower (fostul IEIA), Strada Republicii, nr. 109, etaj 3.
Cart. Zorilor, intersectia dintre Republicii si Observatorului; acess cu autobuzele 35, 46, 50, 43.

(Va trebui sa rugati jos la receptie sa va "trimita" cu liftul la 3 deoarece lifturile merg doar cu cheie.
In caz ca nu va descurcati, gasiti "suport tehnic" la 0751569435 :) - Dragos Andronic (ando)).

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 http://go.microsoft.com/fwlink/?LinkId=260882 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.
