What are the New features implemented in program.cs with previous startup.cs in DotNET

Eliana Blake · Answer

Certainly! In DotNET, the structure of a typical ASP.NET Core application includes two main files: program.cs and startup.cs. Traditionally, the configuration and setup logic were primarily located in the startup.cs file. However, with recent updates and enhancements, there have been new features and improvements that have shifted some of this functionality to the program.cs file. One of the significant new features implemented in program.cs is the introduction of the 'CreateDefaultBuilder' method. This method allows developers to streamline the application setup process by automatically configuring various aspects of the application, such as logging, configuration, and dependency injection. Here is an example snippet demonstrating the usage of 'CreateDefaultBuilder': public class Program { public static void Main(string[] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup (); }); } By leveraging 'CreateDefaultBuilder', developers can reduce boilerplate code and focus more on the core functionalities of their applications. Another notable improvement is the support for hosting environment-specific configuration in program.cs. This enhancement allows for better management of configuration settings based on the environment in which the application is running, such as development, staging, or production. Overall, the shift of certain configuration and setup responsibilities to program.cs from startup.cs in DotNET has made application development simpler, more concise, and easier to maintain. It aligns with the goals of promoting best practices and improving developer productivity.
