c# - Xml Requests do not work -

i cannot bare bones asp.net core web api project work using xml instead of json. please help!

i have created new project , adjustments default configuration add xml formatters...

public void configureservices(iservicecollection services) {     // add framework services.     services.addapplicationinsightstelemetry(configuration);      services.addmvc(config =>     {         config.inputformatters.add(new xmlserializerinputformatter());         config.outputformatters.add(new xmlserializeroutputformatter());     }); } 

my controller contains simple , post methods:

[route("api")] public class messagecontroller : controller {     [httppost]     public void post([frombody] message message)     {      }      [httpget]     public iactionresult get()     {         return ok(new message         {             testproperty = "test value"         });     } } 

when try calling post method content-type: application/xml, api returns 415 unsupported media type. have tried adding consumes("application/xml") attribute controller , still not work.

the works , returns json. however, if add produces("application/xml") attribute controller, returns 406 not acceptable, if provide accepts: application/xml header.

for reason, api rejecting related xml though input , output formatters added have seen in few examples find.

what missing?

i have following thing in startup.cs , works xml , json both. here stick xml. note : ( have consider own class sample)

1. startup.cs

   public void configureservices(iservicecollection services)     {          services.addmvccore()                 .addjsonformatters().addxmlserializerformatters();     } 

2. my httpclient code ( might have missed content type setting have done in stringcotent)

   • two header important : accept , content-type. accept in content negotiation , content-type way client tell server type content client posting.

      httpclient client = new httpclient();  client.baseaddress = new uri( @"http://localhost:5000");  client.defaultrequestheaders.accept.add(new system.net.http.headers.mediatypewithqualityheadervalue("application/xml"));    httpcontent content = new stringcontent(@"<product> <id>122</id> <name>computer112</name></product>",system.text.encoding.utf8 , "application/xml");  // important.  var result = client.postasync("/api/products", content).result;
