R4MVC is a Roslyn based code generator for ASP.NET MVC Core apps that creates strongly typed helpers that eliminate the use of literal strings in many places.

It is a re-implementation of T4MVC for ASP.NET Core projects.

R4MVC runs in the dotnet cli or in Visual Studio 2017/2019/2022, and supports ASP.NET Core MVC 1 and 2

Instead of

@Html.ActionLink("Dinner Details", "Details", "Dinners", new { id = Model.DinnerID }, null)

R4MVC lets you write

@Html.ActionLink("Dinner Details", MVC.Dinners.Details(Model.DinnerID))

When you're using tag helpers, instead of

<a asp-action="Details" asp-controller="Dinners" asp-route-id="@Model.DinnerID">Dinner Details</a>

you can write (after registering R4Mvc tag helpers in _ViewImports.cshtml with the directive: @addTagHelper *, R4Mvc)

<a mvc-action="MVC.Dinners.Details(Model.DinnerID)">Dinner Details</a>

and that's just the beginning!
