Windows 8: Error on video playing

Pentru aplicatiile Metro in Windows 8, adaugarea de video la un view se face destul de simplu, utilizand componente precum MediaPlayer .
<MediaPlayer x:Name="VideoMediaPlayer" AutoPlay="False" Loaded="VideoMediaPlayer_Loaded"/>
...
private void VideoMediaPlayer_Loaded(object sender, RoutedEventArgs e)
{
MediaPlayer player = (MediaPlayer)sender;
IRandomAccessStream videoStream = GetVideoStream();
player.SetSource(videoStream, "video/mp4");
}
Binding-ul la source se poate face in diferite moduri. Nu are importanta cum il faceti. In schimb pe versiunea curenta de Windows 8 ( Consumer Preview) aplicatia voastra o sa crape uneori cand userul face play/stop sau schimba pagina curenta.
Eroarea care se arunca are forme asemanatoare cu aceasta:
Windows.UI.Xaml.UnhandledExceptionEventArgs
Exception from HRESULT: 0xC00D3E85
Call to UIASendMessageTimeout failed
Nu incercati sa faceti FIX la aceasta problema in codul vostru. Problema este un bug pe care Windows 8 CP il are si care o sa fie fix-uit in urmatoarea versiune.
Tot din aceasta cauza uneori poate as apara e eroare de genul:
Error loading from server.
in bare unde se face play/pauze la un video.
Speram ca in urmatorul release aceste probleme se rezolva.

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…
