How can I return XML from a controller action? Even when I add the header Accept: application/xml it returns a JSON object.
WebApi controllers in MVC 5 supported this. What do I have to do to make it work in MVC 6?
Microsoft removed the XML formatter, so that ASP.NET MVC 6 returns only JSON by default. If you want to add support for XML again, call AddXmlSerializerFormatters after services.AddMvc() in your Startup.ConfigureServices() method:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc()
.AddXmlSerializerFormatters();
}
To use it, you have to add "Microsoft.AspNet.Mvc.Formatters.Xml": "6.0.0-rc1-final" as dependency (in the project.json under dependencies).
A slightly more tedious way of doing the same thing would be to add the Xml formatter directly to the OutputFormatters collection:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.OutputFormatters.Add(new XmlSerializerOutputFormatter());
});
}
XmlSerializerOutputFormatter is in the namespace Microsoft.AspNet.Mvc.Formatters.
