Day 4 of Software Architecture 2012 & Agile and OO design

Today was the last day of Software Architect 2012. Last day was dedicated to workshops and I decided to join Allen Holub session: “Agile/OO design from start to finish”. After these days I become a fan of A. Holub and I hope that I will be able to implement a correct OO design. It is pretty challenging, but I promise that I will try to write about this in future.
Here are some notes from the presentation that I considered important. A part of them are well known by all of you:
Agile is based on communication, but there are people that will not be able to integrate in a team environment. Even if they are great on technical side and have a lot of knowledge, they are not able to communicate and to share data. Sharing is one of the most important things in Agile. The biggest enemy for Agile is EGO. Because of this people will not be able to communicate and different roles will appear – “I am the MASTER and the team need to do as I say.” – WRONG.
When we are talking about user-stories, management should understand the concept of points and the relations between points and duration – there is no relationship. Also when the team say, there are 50% percent chances to not be able to finish at time, than the chances are pretty high.
If you have a bunch of user-stories, start with the one that are the most risky. You will need time to clarify and resolve them. Also if you have a complicate or a user story that is very big than you should slit him? One good solution here is for the first sprint to consider only one happy flow, after that another, or an exceptional flow and so on. In this way we will be able to make it more and more complex at each iteration. Your scope is to have something that is fully functional at the end of every iteration.
Be strong and in the moment when someone wants to take off a man from the team say “NO!” This action can affect the project velocity; because of this there are chances not to finish all the user stories at the end of the iteration.
I didn’t use the SCRUM and SPRINT terminology.  Why? SCRUM is not the only way to be AGILE. From some perspective SCRUM is not agile, in the current “implementation”.
I will finish this post blogs about this conference with two cited that I heard today and I like:
“A ‘bug’ is not a logic error; it is a missing unit test.”
“Each team member is responsible for his own word and the team is responsible for the entire project (all the code and artifacts that are generated).”

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:

Run native .NET application in Docker (.NET Framework 4.6.2)

Scope
The main scope of this post is to see how we can run a legacy application written in .NET Framework in Docker.

Context
First of all, let’s define what is a legacy application in our context. By a legacy application we understand an application that runs .NET Framework 3.5 or higher in a production environment where we don’t have any more the people or documentation that would help us to understand what is happening behind the scene.
In this scenarios, you might want to migrate the current solution from a standard environment to Docker. There are many advantages for such a migration, like:

Continuous DeploymentTestingIsolationSecurity at container levelVersioning ControlEnvironment Standardization
Until now, we didn’t had the possibility to run a .NET application in Docker. With .NET Core, there was support for .NET Core in Docker, but migration from a full .NET framework to .NET Core can be costly and even impossible. Not only because of lack of features, but also because once you…
