Introduction
The below features and improvements have been made in .Net 6.
1. Hot Reload
This will allow you to make changes to your code while the application is running and see the changes applied immediately without having to stop and restart the application.
2. Minimal APIs
Minimal APIs are a new feature in ASP.NET Core 6 that allows developers to create lightweight, fast, and easy-to-maintain APIs with minimal setup and configuration. They provide a streamlined API development experience focusing on simplicity and ease of use.
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
app.MapGet("/printhelloworld", () => "Hello, World!");
app.Run();
3. The Merger of the Program and Startup classes
In earlier versions of ASP.NET Core, the program and startup classes were separate classes responsible for different aspects of the application’s configuration and initialization. In .net 6, these classes have been merged into a single class.
Below is an example of the .net 6 program.cs file.
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllers();
var app = builder.Build();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
app.Run();
4. HTTP Logging middleware
HTTP Logging middleware is a component in ASP.NET Core that logs HTTP requests and responses to the application’s log. This can be useful for debugging and troubleshooting purposes, as well as for auditing and compliance purposes.
Include the below code in the program.cs file for enabling http login.
app.UseHttpLogging();
5. Blazor improvements
In ASP.NET Core 6, there are several improvements to Blazor, including improved performance, enhanced debugging and testing tools, and improved support for web standards.
6. Improved support for IAsyncDisposable
IAsyncDisposable is an interface in .NET that allows objects to perform asynchronous cleanup tasks when they are no longer needed. In ASP.NET Core 6, there is improved support for IAsyncDisposable, making it easier to manage resources and improve the performance of asynchronous code.
