Transcript Of The Video. Hi I'm Andrea, and welcome to Productive C#. In this video I want to tell you how you can get started using Autofac. I'm going to do that by taking an application, and introducing the dependency injection framework using Autofac. Since Xamarin.Mac is already a Platform specific project, it makes no sense to have a built in dependency injection system in Xamarin.Mac, unlike Xamarin.Forms which is meant to be references by Xam.Android, Xam.iOS, UWP, and now Xam.Mac platform specific app projects.

The What, How, and Why Dependency Injection in C# can be a really confusing topic. Yet, when done right, Dependency Injection can be one of the best things you do for your application. It allows you to disconnect pieces of your application from each other easily and it allows you to test the various parts of your application independently. Today, I am going to get you started using Dependency Injection using a free tool called Autofac. We will take a small sample application and first apply the Dependency Inversion Principle (the D in SOLID).

Then, we will wire up Autofac to handle connecting the various dependencies together.

Tim, I just discovered your site, and this was one of the best tutorials I’ve ever seen, on any topic. I’m looking forward to checking out your other videos. Could you show how to use Autofac with WPF and MVVM in a future DI video? I’ve been doing some research, but I’m still very lost.

Connecting up views with view models seems quite complicated. I feel you would break it down so the difficulty would be manageable and understandable.

(Also, I’m trying to use Prism, but that might be too much off-topic.).

In this article, we will learn: • What is Dependency Inversion Principle (DIP) • What is Inversion of Control (IOC) • What is Service Locator? • What is Dependency Injection? • Difference between DIP and IOC (DIP vs IoC) • Difference between Dependency Injection and Service Locator (DI vs SL) Many developers get confused with the term Dependency Injection. Mainly on: What is Dependency Injection? Why is it required? What is the mechanism behind Dependency Injection?

In this article we will discuss all these terms in simple words. What is Dependency Inversion Principle (DIP) The Dependency Inversion principle refers to a specific form of decoupling software modules.It states: • High-level modules should not depend on low-level modules. Both should depend on abstractions. • Abstractions should not depend on details.

Outlook for Mac is now more powerful for managing your time across different time zones. We're now shipping two of our most-requested calendar features: display second time zone on Calendar grid, and allow setting of start/end time zones in events. These features are now available to Insider Fast starting from version 14). When you create a new meeting or appointment, Outlook uses the default time zone in your Outlook preferences for Calendar. If you want, you can specify a different time zone for an event as you are creating it. To display the Time zone selector, on either the Organizer Meeting tab or the Appointment tab, click Time Zones. Outlook 2016 mac calendar time zone. If you want to change the primary time zone, you'll need to change the Time Zone on the Mac. However, if your boss is using Outlook for iOS, it is not feasible to use the timezone feature. I totally understand this functionality is very important to people who travel or have business meetings outside their timezone. Yes, you can now use multiple time zones in Outlook for Mac. Microsoft listens to user requests and adds the most popular suggestions, and as of Outlook for Mac version 16.11 (180311), the Calendar supports two time zones.

Details should depend on abstractions The Dependency Inversion principle (DIP) helps us to develop loosely couple code by ensuring that high-level modules depend on abstractions rather than concrete implementations of lower-level modules What is Inversion Of Control (IOC) Inversion of Control is a software design architecture where the framework controls the program flow. It means we are changing the control from normal way. IOC is used to increase modularity of the program and make it extensible.

To understand it better, lets look at an example. When we are writing an ASP.net application, we are in ASP.net page life cycle but not in control where ASP.net is. So as per the above diagram Dependency Injection (DI) and Service Locator (SL) are the ways of Implementing Inversion Of Control (IOC) Difference between DIP and IOC (DIP VS IOC): As stated earlier, DIP says high level module should not depend on low level module for abstraction and IOC provides abstraction.So if you want to make independent higher level module from the lower level module then you have to invert the control so that low level module will not control the interface and creation of the object.

Dependency Injection (DI): • Dependency Injection is a design pattern allows us to write loose coupled code • Dependency Injections helps us to manage future changes in code i.e. code maintainability • Dependency Injection uses a builder object to initialize objects and provide the required dependencies to the object means it allows you to ‘inject’ a dependency from outside the class Service Locator (SL): • Service Locator is a software design pattern that allows us to develop loosely coupled code. • It implements the DIP principle and easier to use with an existing codebase • It introduces a locator object that is used to resolve dependencies within a class. Difference between DI and SL (DI VS SL): The Service Locator allows you to “resolve” a dependency within a class and the Dependency Injection allows you to “inject” a dependency from outside the class. • When you use a service locator, every class will have a dependency on your service locator but in dependency injection,the dependency injector will typically be called only once at startup, to inject dependencies into the main class. • The Service Locator pattern is easier to use in an existing codebase as it makes the overall design loosely coupled without forcing changes to the public interface. Code that is based on the Service Locator pattern is less readable than the equivalent code that is based on Dependency Injection.
