Debug Silverlight application - breakpoint not hit

In cazul in care lucrati cu o aplicatie Silverlight si vreti sa faceti debug s-ar putea sa va treziti nici un brake point nu este atins. Cele mai comune cauze la aceasta probleme sunt:
  • proiectul web care contine XAP nu este setat sa permita debug si la Silverlight. Acest lucru se poate activa in felul urmator: click dreapta pe proiectul web care contine xap-ul. Sub tabul Web in zona de Debuggers, verificati sa fie selectat si Silverlight
  • puteti incerca tot din Properties de pe proiectul web din tab-ul Silverlight Applications sa stergeti link-ul spre proiectul Silverlight si sa il adaugati din nou( in cazul in care nu aveti proiectul adaugat ca si link, checkboxul de la punctul precedent nu o sa fie vizibil
  • verificati ca in browser rulati un url care contine http// si nu file//. Debugul spre linkuri spre local file system este dezactivat
  • nu sunteti atasati la procesul care trebuie( aceasta este o problema a Visual Studio care nu se ataseaza la procesul care trebuie). Pentru a va atasa la proces, cand sunteti in debug este nevoie sa selectati Debug->Attach to Process. Acolo trebuie sa selectati procesul care ruleaza aplicatia voastra( iexplorer.exe, firefox.exe etc)

Daca nici o solutie nu a functionat, atunci puteti incerca sa instalati din nou tool-urile pentru Silverlight, in unele cazuri chiar merge.

In cazul in care vreti sa folosti Firefox, este necesar sa faceti urmatori pasi:

  • Load FireFox
  • Type "about:config" into FF's address bar
  • Accept the warning (if applicable)
  • Search for the entry "dom.ipc.plugins.enabled"
  • Change its value from "true" to "false" (double-click)
  • Restart the browser

Enjoy

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 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:

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…
