Custom XmlSerializer for some types not working in ASP.NET Web API 2.1 -

asp.net web api not invoke xmlserializer registered mytype below -

when place breakpoints in either of myserializer method not heat.

globalconfiguration.configuration.formatters.xmlformatter.usexmlserializer = true;     globalconfiguration.configuration.formatters.xmlformatter.removeserializer(typeof(mytype)); globalconfiguration.configuration.formatters.xmlformatter.setserializer<mytype>(new myserializer()); 

myserializer implemented below -

 public class myserializer : system.xml.serialization.xmlserializer         {             public override bool candeserialize(system.xml.xmlreader xmlreader)             {                 return base.candeserialize(xmlreader);             }             protected override system.xml.serialization.xmlserializationreader createreader()             {                 return base.createreader();             }              protected override system.xml.serialization.xmlserializationwriter createwriter()             {                 return base.createwriter();             }              protected override object deserialize(system.xml.serialization.xmlserializationreader reader)             {                 return base.deserialize(reader);             }               protected override void serialize(object o, system.xml.serialization.xmlserializationwriter writer)             {                 try                 {                     base.serialize(o, writer);                 }                 catch (exception ex)                 {                 }             }         }
