DEPRECATE FOR .NET 8 - USE PRIMARY CONSTRUCTORS

[burtonrodman]

With the introduction of primary constructors in .NET 8, this package will be deprecated.

Injected Services can now be defined tersely using primary constructor syntax:

public class TestService(
    IHttpContextAccessor accessor,
    IWidgetRepository widgetRepository,
    IOptions<EmailSenderOptions> emailSenderOptions)
{
}

Drawbacks (all minor, imho):

• no null checking
• no Options handling
• fields are mutable

[burtonrodman]

while the above is still applicable, and I am using primary constructors much more, I still see value in having null checks generated (especially for non-injection related scenarios).

am considering a generator using the following pattern (as described in this SO post)

[GenerateConstructorNullChecks, UnwrapOptions]
public partial class MyController(
    IMyService myService,
    IOptions<MyControllerOptions> options
) : ControllerBase
{
    
}

would generate something like:

public partial class MyController {
    private readonly IMyService myService = myService ?? throw new ArgumentNullException(nameof(myService));
    private readonly MyControllerOptions options = options.Value ?? throw new ArgumentNullException(nameof(options));
}
