.NET recap

Also showcases automatic releases using semantic-release, and automatic dependency updates using Renovate.

.NET recap. What is new in .net 6 ,7 and 8

Renovate

This repo uses the Renovate bot to keep dependencies up to date. I use Renovate over Dependabot because it is more configurable and has more features.

Lessons

Lessons - Records

• In order to run a LSP for .NET 7 or newer we need to use the https://github.com/razzmatazz/csharp-language-server instead of Omnisharp-roslyn which only goes up to version 6.
• In order for the LSP to cross projects we need a solution file. This is because the LSP needs to know about the projects in the solution in order to provide intellisense across projects.
• Use ReferenceEquals() to compare wheter two reference types are the same object.
• Use struct records for small, immutable data structures that you want to store on the stack. For larger data structures, you will want to use reference type records.
• Renovate need access to create or update workflow in order to create a PR updating gh actions.
• Renovate does not use the full url when spesifying individual repositories

Lessons - WebAPI

• There are mainly two types of ways to create APIs in ASP .NET Core: minimal APIs and MVC.

Lessons - feature-explorer

• Host ConfigureServices does have a method to take in a predefined IServiceCollection.
• ConfigurationBuilder is used to build configuration from different sources, e.g. appsettings.json, appsettings.Development.json, environment variables, command line arguments.
• .NET has a built in feature toggle system that can be used to enable or disable features in your application. It is included in the Microsoft.FeatureManagement package

Use Host.CreateApplicationBuilder if:

• You are working with ASP.NET Core or minimal APIs.
• You want a lightweight and opinionated configuration for modern web applications.
• You are using .NET 7 or newer.

Use Host.CreateDefaultBuilder if:

• You need a generic host for non-web applications, such as worker services or console apps.
• You require full flexibility and customization.
• You are targeting .NET 6 or older (or .NET 7+ for non-web apps).

Build and release

This repo uses gitmoij commits and the semantic-release GitHub Action to automatically create releases. This means that you should use the following commit message format defined in the .releaserc file. See the gitmoij on how to use gitmoij.
