XmlSerializerInputFormatter is obsolete - ASP.NET Core 2.1

Question

I am using the following to accept XML serialized in my Core API App.

services.AddMvc(options =>
{
    // allow xml

According to the source code, there's a constructor that has not been marked as Obsolete:

public XmlSerializerInputFormatter(MvcOptions options)

This constructor takes an instance of MvcOptions, so you can pass through your existing options argument:

services.AddMvc(options =>
{
    // allow xml format for input
    options.InputFormatters.Add(new XmlSerializerInputFormatter(options));
}) ...

As of ASP.NET Core 3.0, this constructor is the only one available. Those that were marked obsolete have now been removed.
