Description

Hello, and welcome to Pluralsight! My name is Scott Allen, and I want to give you a quick overview of my course, C# Fundamentals with Visual Studio 2015. It’s designed to help you learn the essential topics you need for developing with the C# programming language, and covers things building classes, programing with objects, and working with interfaces using the C# language. Along the way, you’ll be using C#, Visual Studio and .NET. When you’re done, you’ll be ready to to tackle your own projects in the C# programming language. From there, you can start exploring working with nulls in C#, as well as designing fluent APIs. I look forward to working with you on C# Fundamentals with Visual Studio 2015, here at Pluralsight.

Description

C# 6 introduces new syntax features for primary constructors, exception filtering, static class usage, and more. We'll examine each of these language features in detail, and also look at the area where Microsoft worked the hardest: the compiler itself. Code-named Roslyn, the new compiler comes with an architecture that makes it easier to build tools and extensions for both the C# and Visual Basic languages.

Start Course
Description

Unexpected null values and NullReferenceExceptions can be a constant source of bugs resulting in wasted time and out of hours support callouts. In this course, Working with Nulls in C#, you're going to learn about the different ways that null values pop up in C# code and how to deal with them. First, you're going to learn the fundamentals of why you get null values and the difference between value and reference types. Next you'll learn how you can use the various C# operators to check for and manipulate nulls. Finally, you'll learn how to think about nulls at a higher abstraction level in your object-oriented code. By the end of this course, you'll understand the different types of objects in C#, how to correctly create nullable value types, how to use C# operators to work with nulls with fewer lines of code, and how to implement the Null Object pattern to remove the need to write repetitive null checking code.

Start Course
Description

When building applications we often deal with groups of things: a user's preferences, a customer's orders, or a product's color choices. To implement these groups of things in C#, we use collections. And to get the most from collections, we need to leverage generics. This course covers how, when, why, and best practices for using C# collections and generics, including arrays, generic interfaces, LINQ, delegates, and Lambda expressions.

Start Course
Description

Do you want code that's maintainable, extensible, and easily testable? If so, then C# interfaces are here to help. In this course, we’ll take a look at how we can use interfaces effectively in our code. We'll start at the beginning ("What are interfaces?") and then explore why we want to use them. Along the way we'll create and implement own interfaces, see how to explicitly implement interfaces, and take a look at dynamic loading, unit testing, and dependency injection. All of which is made possible with interfaces.

Dependency Injection On-Ramp

by Jeremy Clark

2h 38m

Start Course
Description

What is Dependency Injection? The answers to the question seem to cause more confusion than help. This course will get us started on the road to understanding. We'll take an example-based approach to see the problems caused by tightly-coupled code. We'll add Dependency Injection to trade that tight-coupling for loose-coupling. And that loose-coupling makes our applications much easier to extend, maintain, and test. Finally, we'll see how Dependency Injection Containers can provide benefits that would be difficult to implement ourselves. This just scratches the surface. Once we're done, we'll be ready to start our journey on the Dependency Injection superhighway.
