Scaffolding minimal api should use lower case parameter names for generated lambdas

[geometrikal]

Scaffolding minimal api from class with primary key Id capitalises method parameter but uses lower case for route pattern. This causes Connect Services OpenAPI code generation (NSwag) to generate erroneous code.

Steps to reproduce

1. Create simple dto

public class Dto
{
    public string Id { get; set; }
}

2. Scaffold minimal api with read/write endpoints using Entity Framework and OpenAPI enabled. Code generated will look like this:

routes.MapGet("/api/Dto/{id}", async (string Id, PerceptionAnnotationServerContext db) =>
        {
            return await db.Dto.FindAsync(Id)
                is Dto model
                    ? Results.Ok(model)
                    : Results.NotFound();
        })
        .WithName("GetDtoById")
        .Produces<Dto>(StatusCodes.Status200OK)
        .Produces(StatusCodes.Status404NotFound);

Note the parameter name Id instead of id. If scaffolding using controllers, the lower case version is used.

Using dotnet swagger to generate the open api json results in route with lower case, but parameter name capitalised. This in turn causes NSwag to generate incorrect code, where they try to replace {Id} but should be replacing {id}

var urlBuilder_ = new System.Text.StringBuilder();
urlBuilder_.Append(BaseUrl != null ? BaseUrl.TrimEnd('/') : "").Append("/api/Dto/{id}");
urlBuilder_.Replace("{Id}", System.Uri.EscapeDataString(ConvertToString(id, System.Globalization.CultureInfo.InvariantCulture)));
