ASP.NET Core 2.x Web Development

.NET Core

.NET Core is the new kid on the block. So why would I want to use .NET Core?

• What and Why
• Understanding .NET Core: .NET 4.x versus .NET Core
• Supporting multiple runtimes

Visual Studio improvements for ASP.NET Core

With .NET Core Microsoft introduced a new project model, with a lot of emphasis on NuGet packages.

• Understanding the new project structure
• Compile directly to memory
• Installing dependencies with NuGet
• Targeting frameworks and handling differences
• Executing commands and tools
• Handling bundling and minification in .NET Core projects

.NET Core Cross-Platform Capabilities

So how can I build .NET core applications on a Mac or Linux machine?

• Developing ASP.NET Core on any platform
• Generating a .NET Core project using dotnet cli
• Getting started with Visual Studio Code

ASP.NET Core Pipeline

ASP.NET Core easily outperforms all other web hosting solutions. So how did they do that? Here we will look at the ASP.NET pipeline, and how to make it do your bidding.

• Understanding the principle of the ASP.NET Core Pipeline
• Selecting your middleware in the Startup class
• Understanding the need for dependency injection and how to configure it
• Adding your first middleware for serving static files
• ASP.NET Core has its own routing middleware
• Showing proper diagnostics while developing, and not in production

The new ASP.NET Core Configuration

ASP.NET Core allows you to pick and choose where to store your configuration. We will look at the idea behind this and of course how to choose your configuration.

• No more web.config
• Formats: JSON, INI or XML
• Why you should store confidential configuration in environment variables and user secrets
• Different ways of getting configuration to your code
• Using the Options pattern
• Adding your own configuration provider

Logging

Proper logging is essential to find problems in production. .NET Core brings a unified logging approach which you can use anywhere in .NET and also works with your preferred logging framework.

• Why do we need another logging framework
• Choosing from different logging providers
• Understanding logging scopes
• An example: Using NLog
• Logging guidelines and recommendations

OWIN and Middleware

The Open Web Interface for .NET brought a simple standard way for building web servers with .NET. ASP.NET Core built upon this standard and with it you can easily build your own custom extensions for .NET Core.

• What is the OWIN specification
• Project Katana and how to build a webserver with it
• Building your own custom middleware
• Testing your middleware

ASP.NET Core and MVC

Every new version of MVC brings a couple of improvements making it easier for developers to build state-of-the-art web applications. Among other features we will look at taghelpers, which bring a similar concept like Angular directives to the server side.

• Web UI and Web API Unification
• MVC routing changes
• Understanding _ViewStart.cshtml and _ViewImports.cshtml
• Better readable and more powerfull Razor with tag helpers
• Developing and installing your own tag helpers
• Building View Components
• Service Injection
