This also makes it easy to develop a test harness, independent of the application, to test extension components. [ 13 0 R]

Add the following code in the MySimpleCalculator class to implement the Calculate method: The initial steps parse the input string into left and right operands and an operator character. The contract is independent from the type of the importing object. With a complete assembly, we need to load in an application to find the required contract. MEF example code, mefexamplecode. Les MEF spécifiques ULIS sont des MEF nationaux à gestion académique dont le dernier caractère du MEF est « U » : ex : 6EULIS 1001001211U La création dans STS de divisions multi-mef (1 division avec un mef classique + un mef ULIS), est impérative afin de rendre la gestion de ces élèves adéquate à la In this way, extension components themselves are automatically extensible. cette vidéo présente un exemple d'application de la MEF pour l'étude des treillis Created Mar 13, 2017. - Liste des responsables de l'élève (et leur adresse) - Adresse I will be posting this blog in next 2-3 days. This is how we can just keep on adding the required plugs and build the project so it will be available for usage. This is typically accomplished by explicitly registering the available components in a configuration file. <>
With an import, the component specifies a need for a particular value or object, and with an export it specifies the availability of a value. Cette Add the following class to the module or SimpleCalculator namespace: Here is the export that will match the import in Program. il faut accéder à l'application SCONET BOURSES DES COLLEGES. 27 0 obj
An ordinary ImportAttribute attribute is filled by one and only one ExportAttribute. Liste In addition to that we will also need to add the reference of the ‘System.ComponentModel.Composition.dll’ available from the MEF download from CodePlex. 13 0 obj
Before reading this article, I would recommend reading the following article. The most common type of composition container is CompositionContainer, and you'll use this for SimpleCalculator.

MEF not only allows extensions to be reused within applications, but across applications as well. Your application has to include a potentially large number of smaller components, and is responsible for creating and running them. The PlugBoard is the folder were all calculator libraries will be placed. page permet de consulter les informations enregistrées pour un élève The DirectoryCatalog will now add any parts found in any assemblies in the Extensions directory to the composition container. ���"�c
Since the composition container will be populated with all the parts available in this assembly, the MySimpleCalculator part will be available. 7 0 obj

What I feel is MEF is an extensibility framework provided by Microsoft. This is where all the exported values will be stored. It allows application developers to discover and use extensions with no configuration required. <>
In Module1.vb or Program.cs, add the following line to the Program constructor: Replace the example path with the path to your Extensions directory. These two namespaces contain MEF types you will need to develop an extensible application. Let us add two more Class Library Projects to the same solution namely ‘Impl1’ and ‘Impl2’. Signale la division où l'élève a été Code needs to be updated to either Dynamically identify and update or give an option to user something like (e to Exit and r to refresh). Adding classes to the source code is simple enough, but MEF provides the ability to look outside an applicationâs own source for parts. l'année précédente. To use MEF you need to include the following reference in your project:System.ComponentModel.CompositionWe need to define a container. Si Sconet BEE est ouvert sur l'année en cours Your best explanation make me easy to do my project.. Nice.. . The new project will compile into a separate assembly. If the application architect has not anticipated the need for a particular communication, it is usually impossible. #2: We need to present the user with the implementation options available in the extensions folder and user can choose the extension and only the corresponding implementation is used. Below is the output snap of window where you can now see 2 more options plugged to the main calculator application with the names “Table Calci” and “Trigonometry”. Create a project of type Class Library and name it as Plugger. scolaire correpondant à la "scolarité actuelle". <>
fH���D�v��B�5?LWI��FB�+������� (This is one of several ways to access metadata in MEF. Now we will add ‘Hello.cs’ class that will implement the IHello interface to both of these Projects with the implementation of SayHello method as mentioned below: We are ready with the Contract information and there are two implementations of that Contract. 24 0 obj
MEF. You can use MEF in your client applications, whether they use Windows Forms, WPF, or any other technology, or in server applications that use ASP.NET. endobj
That is all the code you need in Program. endobj
Add this very simple interface to the module or SimpleCalculator namespace: Now that you have defined ICalculator, you need a class that implements it. 23 0 obj

Supprimer la bourse de l'élève sur la ligne corresponsante, Revenir Add the following code to the Main method: This code simply reads a line of input and calls the Calculate function of ICalculator on the result, which it writes back to the console. This makes it difficult for a component to be used in more than one application, and can also create problems when you create a test framework for components. The ExportMetadataAttribute attribute attaches metadata, in the form of a name-value pair, to that export. Signale le nom de l'établissement We will create a Consol App that will have a reference of the Contract dll along with ‘System.ComponentModel.Composition.dll’. un lycée de Perpignan et dans un collège situé à Canet en Roussillon, respectivement : - Lycée Pablo Picasso, 120 Avenue Général Gilles, 66000 Perpignan (04 68 50 04 13) - Collège Côte Radieuse, 39 Avenue de Perpignan 66140 Canet en Roussillon (04.68.73.59.70 ) SCONET BOURSES DES COLLEGES. information a une influence sur la gestion financière de l'établissement. If you're looking for the current MEF code base, you should go to CoreFx. In order for the export to match the import, the export must have the same contract. ), In this article, we have seen how we can develop a plug and play solution to meet our requirements which need extensibility using MEF Framework, /// It will return UserControl which will display on Main application, "http://schemas.microsoft.com/winfx/2006/xaml/presentation", "http://schemas.microsoft.com/winfx/2006/xaml", "http://schemas.microsoft.com/expression/blend/2008", "http://schemas.openxmlformats.org/markup-compatibility/2006".
