By default Xml formatters are not included as part of the Microsoft.AspNet.Mvc package. You need to reference another package called Microsoft.AspNet.Mvc.Xml for this.

Example on how you can add the formatters:

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.ConfigureMvc(options =>
    {
        // This adds both Input and Output formatters based on DataContractSerializer
        options.AddXmlDataContractSerializerFormatter();

        // To add XmlSerializer based Input and Output formatters.
        options.InputFormatters.Add(new XmlSerializerInputFormatter());
        options.OutputFormatters.Add(new XmlSerializerOutputFormatter());
    });
