Module 1: Exploring ASP.NET Core MVC
Microsoft ASP.NET Core MVC and the other web technologies of the ASP.NET Core can help you create and host dynamic, powerful, and extensible web applications. ASP.NET Core, of which ASP.NET Core MVC is part, is an open-source, cross-platform framework that allows you to build web applications. You can develop and run ASP.NET Core web applications on Windows, macOS, Linux, or any other platform that supports it. ASP.NET Core MVC supports agile, test-driven development cycle. It also allows you to use the latest HTML standard and Front-End frameworks such as Angular, React, and more.

Module 2: Designing ASP.NET Core MVC Web Applications
Microsoft ASP.NET Core MVC is a programming model that you can use to create powerful and complex web applications. However, all complex development projects, and large projects in particular, can be challenging and intricate to fully understand. Without a complete understanding of the purposes of a project, you cannot develop an effective solution to the customerís problem. You need to know how to identify a set of business needs and plan the Model-View-Controller (MVC) web application to meet those needs. The project plan that you create assures stakeholders that you understand their requirements and communicates the functionality of the web application, its user interface, structure, and data storage to the developers. By writing a detailed and accurate project plan, you can ensure that the powerful features of MVC are used effectively to solve the customerís business problems.

Module 3: Configure Middlewares and Services in ASP.NET Core
ASP.NET Core is a framework that allows us to build many different kinds of applications. In this module, you will learn how to leverage the ASP.NET Core framework to handle requests and responses via existing, and custom middleware, and how to configure services for use in middleware and throughout other parts of the application, such as controllers. A middleware is a segment of code that can be used as part of the request and response pipeline that allows us to handle them according to any relevant parameter. This potentially allows multiple separate requests to be handled in a completely different fashion and receive separate responses. Services are classes that expose functionality which you can later use throughout different parts of the application, without having to keep track of scope manually in each individual location and instantiate any dependencies. This is done by using Dependency Injection. Dependency Injection is a technique used by ASP.NET Core that allows us to add dependencies into the code without having to worry about instantiating objects, keeping them in memory, or passing along required dependencies. This allows the application to become more flexible and to reduce potential points of failure whenever you change a service.

Module 4: Developing Controllers
ASP.NET Core MVC is a framework for building web applications by using the Model-View-Controller (MVC) architectural pattern. The controller is essentially responsible for processing a web request by interacting with the model and then passing the results to the view. The model represents the business layer, sometimes referred to as the domain, and may include data objects, application logic, and business rules. The view uses the data that it receives from the controller to produce the HTML or other output that is sent back to the browser. In this module, you will learn how to develop controllers. Controllers are central to MVC applications. Understanding how controllers work is crucial to being able to create the appropriate model objects, manipulate them, and pass them to the appropriate views. A controller is a class. It contains several methods. These methods are called actions. When an MVC application receives a request, it finds which controller and action should handle the request. It determines this by using Uniform Resource Locator (URL) routing. URL routing is another very important concept necessary for developing MVC applications. The ASP.NET Core MVC framework includes a flexible URL routing system that enables you to define URL mapping rules within your applications. To maximize the reuse of code in controllers, it is important to know how to write action filters. You can use action filters to run code before or after every action in your web application, on every action in a controller, or on other combinations of controller actions.

Module 5: Developing Views
Views are one of the three major components of the Model-View-Controller (MVC) programming model. You can define the user interface for your web application by creating views. A view is a combination of HTML markup and C# code that runs on a web server. Therefore, to create a view, you need to know how to write the HTML markup and C# code and use the various helper classes that are built into MVC. You also need to know how to create partial views and view components, which render sections of HTML that can be reused in your web application.

Module 6: Developing Models
Most web applications interact with various types of data or objects. An e-commerce application, for example, manages products, shopping carts, customers, and orders. A social networking application might help manage users, status updates, comments, photos, and videos. A blog is used to manage blog entries, comments, categories, and tags. When you write a Model-View-Controller (MVC) web application, you create an MVC model to model the data for your web application. Within this model, you create a model class for each type of object. The model class describes the properties of each type of object and can include business logic that matches business processes. Therefore, the model is a fundamental building-block in an MVC application. In this module, you will learn how to create the code for models.

Module 7: Using Entity Framework Core in ASP.NET Core
Web applications often use information and they usually require a data store for that information. By rendering webpages that use data from a data store, you can create a web application that changes continually in response to user input, administrative actions, and publishing events. The data store is usually a database, but other types of data stores are occasionally used. In Model-View-Controller (MVC) applications, you can create a model that implements data access logic and business logic. Alternatively, you can separate business logic from data access logic by using a repository. A repository is a class that a controller can call to read data from a data store and to write data to a data store. When you write an ASP.NET application you can use the Entity Framework Core (EF Core) and Language Integrated Query (LINQ) technologies, which make data access code very quick to write and simple to understand. In this module, you will see how to build a database-driven website in MVC.

Module 10: Testing and Troubleshooting
Software systems such as web applications are complex and require multiple components, which are often written by different developers, to work together. Incorrect assumptions, inaccurate understanding, coding errors, and many other sources can create bugs that result in exceptions or unexpected behavior. To improve the quality of your web application and create a satisfying user experience, you must identify bugs from any source and eliminate them. Traditionally, testers perform most of the testing at the end of a development project. However, it has recently become widely accepted that testing throughout the project life cycle improves quality and ensures that there are no bugs in production software. You need to understand how to run tests on small components of your web application to ensure that they function as expected before you assemble them into a complete web application. It is also important that you know how to handle exceptions while they occur. While an application is running, you may encounter unexpected occurrences. It is important that you manage your exceptions correctly and provide a good user feedback while avoiding leaking information about the application structure. Finally, by using logs throughout the application, you can monitor user activities that might lead to unexpected issues and then you can find solutions to bugs, which you normally would be unsure how to reproduce, by following flows which occurred on the production environment and finding additional errors.

Module 11: Managing Security
Since web applications are normally targeted towards users utilizing only a browser to use the application, there are likely to be far more users than in the case of installed applications. However, the open nature of a web application means security must always be at the forefront of your mind when building them. As part of security, you must decide which users can perform what actions, all while protecting users and your application from malicious third parties with possible access to your application. Authentication is the act of utilizing several parameters to make sure that a user is who they claim to be. By implementing authentication, you can ascertain who a user is and provide them with appropriate content while utilizing your applications. Authorization is the process where an already authenticated user in the application can be granted access to specific actions or resources. By utilizing authorization, you can prevent users from accessing sensitive material not intended from them or from performing actions which they should not be able to. Finally, at some point in its lifespan, your applications may come under attack by malicious users. These can vary in means and intent, but the cost of being undefended can be great. You may lose potential users who are affected, valuable data could be erroneously changed, and in the worst cases the entire application may become unusable. Solutions to some of the most popular attacks will be reviewed in this module.

Module 12: Performance and Communication
Modern web applications require complex interactions with users. Users will often request a lot of data in a small time-frame, while also expecting relevant data as soon as it comes online. This can easily cause a significant amount of load on an unprepared server, resulting in unnecessarily complex or repeated operations and a heavy load on your server. Fortunately, there are multiple ways to reduce the load. Caching allows you to store commonly repeated requests, preventing the need to perform the same logic repeatedly. By using caching, you can reuse data that has already been loaded and present it to the user. This provides the user with a fast response time and reduces system resources used in conducting the logic for the action. State meanwhile allows achieving a state of consistency between different requests. By utilizing various forms of state management, you can transform the normally stateless web experience into one that is custom tailored to individual clients, with different users enjoying a separate and relevant experience in the same application. Finally, SignalR is a framework that allows the abstraction of several different communication protocols into an easy to use API, which allows you to easily create a single set of tools on the server and client to facilitate two-way communications. This allows you to focus on the logic you wish to implement while allowing you to not have to cater to specific browsers.

Module 13: Implementing Web APIs
Most web applications require integration with external systems such as mobile applications. You need to know how to use Web APIs to promote application interaction with external systems. You can use the Web API to implement Representational State Transfer (REST) services in your application. REST services help reduce application overhead and limit the data that is transmitted between client and server systems. You need to know how to call a Web API by using server-side code and jQuery code to effectively implement REST-style Web APIs in your application.

Module 14: Hosting and Deployment
ASP.NET Core MVC applications are designed to provide a service to multiple users simultaneously while only requiring the server to be installed, and the clients to use browsers to access it. This results in highly desirable applications which do not rely on the user installing dedicated software, and ensuring it is accessible by clients on a wide variety of machines. In order to setup an ASP.NET Core application for a production environment, you will need to compile your code and compress it, and then set it up and running on a dedicated server. Hosting involves using a dedicated server to contain the compiled application and serve it to users as a web-based service. There are many different technologies which can be used to host your application and you should choose one that is appropriate for your requirements. Deployment is the process where the project code is compiled and then transferred to the hosting server in a way that functions within the requirements of the hosting environment. Microsoft Azure is a cloud service provided by Microsoft. It can be used to host ASP.NET Core applications, and is a popular tool in the cloud technology market. It provides convenient Web Application related services at multiple billing options according to requirements.
