Creating ASP.NET Core Web Applications

Design and develop an ASP.NET Core web application using .NET Core 3.0. This book shows you how to publish a web application to a web server and connect the published web application to a production database.

CREATING ASP.NET CORE WEB APPLICATIONS starts by setting up the Visual Studio project where you will learn about Razor pages, Entities, and creating a data service. You will create models along with methods to use a query string and handle bad requests. Modifying data with Tag helpers is discussed as well as installation of Entity Framework, working with database migrations, and implementing a data access service. You will learn how to use layout pages and sections with Partial Views, _ViewImports, and _ViewStart files. You also will create custom middleware and log application events. You will be able to deploy the web application as well as connect it to a SQL Server database.

WHAT YOU WILL LEARN

* Work with models
* Modify data
* Work with EF Core and SQL Server
* Work with Razor pages and Partial Views
* Use separate scripts for production vs development
* Trace client-side errors using Chrome Developer tools
