Beginning Modern C# and .NET Development

This video provides the overview of this section.              

This video explains the basics of C#. It also provides guidance on how to manage projects with Visual Studio 2017. You can also explore: 

• C# grammar
• C# vocabulary
• C# keywords
• Writing the code
• Counting types and methods

This video explains how to name variables, store texts and numbers. It also suggests improvements in C#. Some of the other features explained in the video are:

• Naming variables
• Literal values
• Storing text, numbers, and Booleans
• C# 7 improvements
• Local variables
• Making a value type nullable
• Storing multiple values in an array

This video explains how console applications are text-based and they run at the command prompt. They typically perform simple tasks that need to be scripted, such as compiling a file or encrypting a section of a configuration file. To build a console application, let's begin by:

• Displaying output to the user
• Getting input from the user
• Importing a namespace
• Reading arguments and working with arrays
• Viewing the output

This video explains how operators apply simple operations such as addition and multiplication to operands such as numbers. They usually return a new value that is the result of the operation. You can also: 

• Experiment with unary operators
• Experiment with arithmetic operators

This video provides the basic expectations required from this section.       

This video explains how every application needs to be able to select from choices and branch along different code paths. The two selection statements that are available in C# are if and switch.

You can use if for all your code but switch can simplify your code in some common scenarios. To understand selection statements effectively, you need to:

• Implement a simple if statement
• Implement the new pattern matching feature of C# using the if statement
• Implement a simple switch statement
• Implement pattern matching using a switch statement

This video explains how iteration statements repeat a block either while a condition is true or for each item in a group. The choice of which statement to use is based on a combination of ease of understanding to solve the logic problem and personal reference. To understand iteration statements, you need to:

• Implement a simple while statement
• Implement a simple do statement
• Implement a simple for statement
• Implement a simple for each statement

In this video, you will often need to convert between different types. Some of them are:

• Cast an int variable into a double variable
• Cast a double variable into an int variable
• Use the System.Convert type for conversions
• Check how numbers are rounded in C#
• Convert to the string type
• Parse to numbers or dates and times

In this video you will learn about handling exceptions. You've seen several scenarios when errors have occurred. C# calls where an exception has been thrown. A good practice is to avoid writing code that will throw an exception whenever possible, but sometimes you can't. In those scenarios, you must catch the exception and handle it. Some ways of handling exceptions are:

• Catch exceptions using the catch block
• Catch specific exceptions
• Use finally statement

In the earlier video, we saw that when casting between number types, it was possible to lose information. In this video, we will see how the value will overflow if it is stored in a type that is too big. To check for overflow, you can:

• Use the checked statement
• Use the unchecked statement

This video summarizes what we have learned in the earlier topics.

This video explains how class library assemblies group types together into easily deployable units (DLL files). Apart from when you learned about unit testing, you have only created console applications to contain your code. To make the code that you write reusable across multiple projects, you should put it in class library assemblies, just like Microsoft does. The steps involved in building class libraries are:

• Create a class library with Visual Studio 2017
• Import a namespace
• Define methods with tuples
• Define read-only properties
• Define an indexer
• Define an event

In this video, we will start by defining a solution/project. If you have completed all the previous activities, then you can open your project and continue with it. To implement interfaces and inherit classes, you have to:

• Implement interfaces
• Use local function to implement a factorial calculation
• Define a comparer
• Add some employee-specific members to extend the class
• Implement polymorphism
• Use static for reusability

In this video, we will understand object-oriented programming. In C#, we use class (usually) or struct (rarely) to define each type of object. You can think of a type as being a blueprint or template for an object.      

This video summarizes what we have learned in the earlier topics.

One of the most common places to store data is in a Relational Database Management System (RDBMS). Common ones include Microsoft SQL Server, Oracle, and SQLite. Let us begin by:

• Creating a database
• Managing a database 

The Entity Framework (EF) was first released as part of .NET Framework 3.5 with Service Pack 1, back in late 2008. Since then, it has evolved, as Microsoft has observed how programmers use an object-relational mapping (ORM) tool in the real world. We will now see how to work on:

• Setting up the Entity Framework
• Retrieving a product from the database
• Implementing a logger
• Adding a product to the database
• Updating the price on the database

This video summarizes what we have learned in the earlier topics.

This video explains that UWP is Microsoft's latest technology solution to build applications for its Windows suite of operating systems. UWP provides a guaranteed API layer across multiple device types. You can create a single app package that can be uploaded to a single store to be distributed to reach all the device types your app can run on. These devices include Windows 10, Windows 10 Mobile, Xbox One, and Microsoft HoloLens. To do this, you have to: 

• Adapt to Your App's Layout
• Take Advantage of Unique Device Capabilities 

In 2006, Microsoft released Windows Presentation Foundation (WPF), which was the first technology to use XAML. It is still used to create desktop applications. XAML can be used to create:

• UWP apps for Windows 10, Windows 10 Mobile, Xbox One, and Microsoft HoloLens
• Windows Store apps for Windows 8 and 8.1
• WPF applications for the Windows desktop, including Windows 7 and later
• Silverlight applications for web browsers, Windows Phone, and desktop

To be able to create apps for UWP, you must enable developer mode in Windows 10. Let us begin by:

• Creating an app for UWP
• Replicating Controls

When building graphical user interfaces, you will often want to use a resource, such as a brush, to paint the background of controls. These resources can be defined in a single place and shared throughout the app. To use resources and templates effectively, you have to:

• Share resources
• Replace a control template

When building graphical user interfaces, you will often want to bind a property of one control to another or to some data. To do this, you have to:

• Bind properties to elements
• Bind properties to data

This video is about how Microsoft ASP.NET Core is part of a history of Microsoft technologies used to build web applications and services that have evolved over the years. To understand ASP.NET Core effectively, you have to:

• Record HTTP Requests and Responses
• Create an ASP.NET Core project with Visual Studio 2017
• Perform Database Migration
• Review Authentication with ASP.NET Identity

This video will walk you through the parts that make up a modern ASP.NET Core MVC application. To explore an ASP.NET Core MVC Web application, you have to first:

• Begin with ASP.NET Core Startup
• Understand the Default Route

This video summarizes what we have learned in the earlier topics.
