How to pass xml input (request) to Web api on .net core 3.1

I have a .net core 3.1 web api. I have tried the following but it always turns up null when it hits it

[HttpPost]     
    public IActionResult ReturnXmlDocument(HttpRequestMessage request)
    {
        var doc = new XmlDocument();
        doc.Load(request.Content.ReadAsStreamAsync().Result);        
        return Ok(doc.DocumentElement.OuterXml.ToString());
    }

It doent even hits it during debugging also it shows a 415 error in fiddler.

For newer versions of .NET Core

The previous answer from mj1313 was correct, but the "Microsoft.AspNetCore.Mvc.Formatters.Xml" library is now deprecated and no longer maintained.

I found a more simple and still valid solution for .NET Core MVC apis, just add this ".AddXmlDataContractSerializerFormatters()" method call to your Program.cs file:

public void ConfigureServices(IServiceCollection services)
{
     services.AddControllers().AddXmlDataContractSerializerFormatters();
}

Asp.net core no longer uses HttpRequestMessage or HttpResponseMessage.

So, if you want to accept a xml format request, you should do the below steps:

1.Install the Microsoft.AspNetCore.Mvc.Formatters.Xml NuGet package.

2.Call AddXmlSerializerFormatters In Startup.ConfigureServices.

public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers()
            .AddXmlSerializerFormatters(); 
    }

3.Apply the Consumes attribute to controller classes or action methods that should expect XML in the request body.

 [HttpPost]
    [Consumes("application/xml")]
    public IActionResult Post(Model model)
    {
        return Ok();
    }

For more details, you can refer to the offical document of Model binding
