Library of standards implemented to use in ASP.NET Core.

For example, it provides convenient abstractions for enforcing DateTime objects are binded with ISO-8601 format (YYYY-MM-DD) in MVC.

Compatibility

Standards.AspNetCore currently targets .NET 6+. We follow the .NET Core support policy and therefore support only the LTS versions. When an LTS version goes out of support, we will update the major version of the library, drop support for the previous LTS version, and only target the next LTS version.

Getting Started

Standards.AspNetCore is available as a NuGet package.

Features

IsoDateModelBinder and IsoDateModelBinderProvider

Useful for ensuring consistent Date format contracts in RESTful APIs. IsoDateModelBinder enforces DateTime model binding with ISO-8601 format (YYYY-MM-DD) in MVC. This can be used in two ways:

1. In single Controller actions:

[HttpGet]
public IActionResult Get([ModelBinder(typeof(IsoDateModelBinder))] DateTime date) {
    return Ok("Date is in ISO format");
}

2. Set globally in the application via Startup:

public override void ConfigureServices(IServiceCollection services) {
    services.AddControllers(options => {
        options.ModelBinderProviders.Insert(0, new IsoDateModelBinderProvider());
    })
}

Then, only dates in ISO-8601 format (YYYY-MM-DD) can be binded. For example, /api?date=2021-01-01 will be successfully binded. However, /api?date=01-01-2021 will not, and the following error message will be added to the problem details response:

"Invalid date; must be in ISO-8601 format i.e. YYYY-MM-DD."

Roadmap

Currently only IsoDateModelBinder is implemented. The intention is for further useful international standards to be implemented in this library.
