Programmatic use of tag helpers

[dharmatech]

Background

Giraffe is an F# web framework built on ASP.NET Core.

mvc-movie-giraffe is a port of the MvcMovie project from the ASP.NET Core documentation to F#/Giraffe.

The C# version of MvcMovie demonstrates the use of tag helpers. Giraffe doesn't yet have any equivalent of tag helpers, so I've started to look into rolling my own version of a few of them.

Example

The Movie class of the original C# project has the following property:

[StringLength(60, MinimumLength = 3), Required]
public string Title { get; set; }

Here the input tag helper is being used in the C# version of the edit view:

<input asp-for="Title" class="form-control" />

It expands into:

<input 
    class="form-control"
    type="text"
    data-val="true"
    data-val-length="The field Title must be a string with a minimum length of 3 and a maximum length of 60."
    data-val-length-max="60"
    data-val-length-min="3"
    data-val-required="The Title field is required."
    id="Title"
    maxlength="60"
    name="Title"
    value="Enter the Dragon" />

I have a minimal F# version of the input tag helper in TagHelpers.fs.

Example of calling it:

TagHelpers.input typedefof<Movie> "Title" (string model.Title) [ _class "form-control" ]

That expands into:

<input 
    class="form-control"
    type="text"
    data-val="true"
    data-val-length="The field Title must be a string with a minimum length of 3 and a maximum length of 60."
    data-val-length-max="60"
    data-val-length-min="3"
    maxlength="60"
    data-val-required="The Title field is required."
    id="Title"
    name="Title"
    value="Enter the Dragon">

Question

It would be really nice if users of Giraffe could benefit from all the tag helpers that are already provided by ASP.NET Core.

Is there a way to programmatically use the tag helpers directly from C# or F# instead of implicitly from a cshtml view file?

Thanks for any suggestions!
