Why Workspace? Why Mef? What HBD?


As recently, I’d shared a few libraries that allow developing a Workspace, and many people asked me, What is Workspace and Why should We care about it?

So, I come up with this post to share a few advantages of the Workspace. I’m not talking about disadvantage here because every Framework has the pros and cons itself. However, We choice it because it was suitable for our company, our departments and our teams or in other words is our customers choice it.

The Advantages Of the Workspace

  1. When developing a new application, we need to build the framework, define the project’s structure, the theme and layout in the IDE and beside of that we need to implement the services that will be used in the application as authentication service, workflow service, input, and output services. What happen if there are so many applications are developing on the different teams in your department, and eventually, each team come up with an application that has difference theme, layout, and components. Just consider Workspace is a Framework and it will help to manage the layout, theme, services consistently between the development teams. It also advises removing the duplication efforts when two or three teams are implementing the similar components.
  2. The other case. In your department, there are a hundred websites are operating and now your company just released a new logo and requested to replace the logo on all application. So, how many teams need to involve and how long it take? As you know re-branding is not only a logo but also the theme, color table, and fonts of the application are getting changed. However, if you have a Workspace you just need to enhance and re-deploy it again without impact to the modules.
  3. Let’s see, If your department already had the Workspaces. So when any team wants to build a new application they can use that Workspace as a framework and start to develop their modules instead of taking time for solution structure, framework defination, theme, and layout creation for the application.

The other Advantages already shared on the previous post. I would like to bring them here so that We will have a general view on it.

  1. Let’s imagine, if you have many development teams and tring hard to make the teams work independently and parallely. However, if three or four teams are working a the significant changes of a complex application and that application does not support modularization. So when any team needs to deploy the changed to the Stagings or Production environments, they need to inform all the other teams to ensure there is no conflict between the teams. After deployed, the other teams need to merge the changes into their source code branches. Managing this situation is a nightmare for the project manager.
  2. The other scenario, if the application doesn’t support modularization, so any change even the small one you need to conduct the System Integration Test (SIT) and User Acceptant Test (UAT) for the whole system because of the impact and the efforts will charge back to the business. You know, the business users may surprise why the simple change is costly?
  3. Micro-Services adoption: as you know, Micro-service is new technology that structures an application as a collection of loosely coupled services, which implement business capabilities. The microservice architecture enables the continuous delivery/deployment of large, complex applications. It also enables an organization to evolve its technology stack.

Why’s Mef

I’ve worked on many Dependency Injections as Ninject, AutoFax, Unity, QuickInject and StructureMap.

The functionality of them is the same because they have been implemented based on Ioc, Dependency Injection concepts. Similarly, The Mef had been released sine the .Net Framework 4.0

Only one thing different between the libraries is the way to import the type mapping and export the objects from the DI container.

If you ask me Why I like Mef? The answer is because of Love. The crazy love without reason. I think the accepted answer is because She is Microsoft’s daughter.

Hope the answer satisfies you.

What is HBD?

HBD (Hoang Bao Duy) is just a lazy, foolish developer, and all his projects were supposed for personal used only.

All HBD projects had been developed by himself. Obviously, There are a lot of silly code in his projects. If you found it, please help to point it out, that is the way you help him grow.

He is not recommending to use his library on your company projects because the enterprise project framework should be verified carefully by the professional development and testing teams.

Saying that doesn’t mean the libaries were came up with poorly quality. Just want to share more information about HBD libraries, all had been tested carefully before publishing, beside that the vulnerability scanning, code quality scaning are applied by using Sonarqube.comWhitesource-Bolt. The unit tests, code UI tests also a part of his projects in order to ensure all functionality of the libraries are working as expected. Furthermore the author had trying his best to improve the libraries, add new features and hotfix the defects promptly.

However, if you want to implement something but don’t know how to start or you want to have some referent code then the HBD open source projects are for you.

Source Code

All HBD projects had been published in here.
