Story - Developers that don’t understand the business of the application

This days I participate to a presentation of a product. The idea of the product was great, I think that they will have a lot of success in the future.
Being a technical presentation, the presentation was held by one of the developers of the team. From this point of view this was great, because the audience was developers and other technical person. He could respond to a lot of question related to architecture, scalability, protocol that were used, base concept and so on.

Until….

Someone asked about something related to business idea and what kind of problem this application will solved….

In that moment our developer stopped……..

He could not give an answer….

And…he sad…
I’m a technical person, is not my business to know the business of the application!

In that moment I freeze. How the hell you can develop an application without understand the business? This is one of the biggest mistakes that can be done by a team member – refuse to understand the business of the application. Before thinking to a solution it is a have to understand the business of the application itself.
How you can resolve a problem without understanding the problem itself?
Being a monkey, a monkey with keyboard is great for a monkey. But when you need to solve a problem and give a solution, being a monkey with keyboard is not enough… This is how you end up with an airplane when a customers wanted a car.

  1. a simple developer should at least try to understand the client business and show the desire to do so - if he is prevented to do so, as it happens sometimes, that's another story..

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…
