Make HttpMethodActionConstraint public in Core 3.0

[EvilBeaver]

Is your feature request related to a problem? Please describe.

I'm making my own ApplicationModelProvider. Before Core 3.0 I used an HttpMethodActionConstraint in my ActionModels to filter out actions by http method.

In Core 3.0 HttpMethodActionConstraint was made an internal class. Why?

Example: 'm trying to do

var selectorModel = new SelectorModel();
selectorModel.ActionConstraints.Add(new HttpMethodActionConstraint(httpMethods));

Describe the solution you'd like

I want to use an existing reusable class HttpMethodActionConstraint from Microsoft.AspNetCore.Mvc.ActionConstraints instead of making my own.

Describe alternatives you've considered

alternative solution. Copy/Paste source of Microsoft.AspNetCore.Mvc.ActionConstraints.HttpMethodActionConstraint in my project

Additional context

Custom ApplicationModelProvider is used for integration with database-provided model. I don't need an AspNetCore's class-based model, but want to use all other stuff. AppModels are great and limitation of their's building blocks is making me sad.

The type was pubinternal in 2.x and we defaulted to making it internal as part of #4932. If your app uses endpoint-routing, you may use HttpMethodMetadata instead. It's what MVC does under the hood - https://github.com/aspnet/AspNetCore/blob/c565386a3ed135560bc2e9017aa54a950b4e35dd/src/Mvc/Mvc.Core/src/Routing/ActionEndpointFactory.cs#L249-L253.

If you are unable to use endpoint routing, we'd be happy to consider a PR to make the type public.

Hi @pranavkm sorry for writing to a closed issue but we have a similar problem. We are using HttpMethodActionConstraint in two places of our custom IApplicationModelConvention implementation to prevent usage of http verbs for some auto generated controllers, see below lines:

https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp.AspNetCore/AspNetCore/Mvc/Conventions/AbpAppServiceConvention.cs#L122
https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp.AspNetCore/AspNetCore/Mvc/Conventions/AbpAppServiceConvention.cs#L229

I tried to change this but couldn't succeed without using HttpMethodActionConstraint. Do you think it is possible to achieve this without using HttpMethodActionConstraint ?
