RedirectToAction() makes the link to HttpPost action instead of GET

[IgorXq]

Hi !
For GET and POST methods with the same action names,

Microsoft.AspNetCore.Routing.DefaultLinkGenerator[105]
     [2020-06-18 14:05:13.651]: Link generation succeeded for endpoints 

generates lincorrect link that in my case eventually led to "too many redirects". (as far as I have investigated, it happens because the link is generated to HttpPost method instead of HttpGet when they both have the same name)

The issue happens for route patterns such as [Route("[controller]/{parameter}/action}")]

and does not happen for the route patterns like [Route("[controller]/action/{parameter}")]

Just to mention, HttpPost action has route pattern [Route("[controller]/action")] (parameter passes in ViewModel)

I have managed with the issue having renamed POST methods so that their names don't match with GET methods.

As for me, such behavior seems incorrect (as well as that RedirectToAction considers POST methods at all to generate links) or I might have lack of knowledge about ASP.Net core MVC routing.

@IgorXq thanks for contacting us.

Can you provide a minimal repro project and host it somewhere public (GH repo or upload it as a zip here) so that can make sure we are not missing any detail?

@javiercn thank you for a quick response.

Please check the demo project here

https://github.com/IgorXq/mvcdemo

If you run it, you can open the URL

http://localhost:5105/Dashboard/mytenant/same

that leads to the example page with correct and incorrect links formed by asp tag helpers.

The page http://localhost:5105/Dashboard/mytenant which should redirect to the url above, indeed ends up with "too many redirects" failure because of the link to the action
