How to get ODataSerializerProvider to respond all request types?

I have created a customized ODataSerializerProvider in order to change odata output using ODataEntityTypeSerializer. But my custom ODataEntityTypeSerializer does not fire on every request. The only differences I guess affect this is Request Headers Accept and Accept-Encoding.

How I can get ODataSerializerProvider to respond all request types?

Here it is my codes:

    public class CustomDefaultODataSerializerProvider : DefaultODataSerializerProvider
{
    CustomODataEntityTypeSerializer _customODataEntityTypeSerializer;

    public CustomDefaultODataSerializerProvider()
    {
        _customODataEntityTypeSerializer = new CustomODataEntityTypeSerializer(this);
    }

    public override ODataEdmTypeSerializer GetEdmTypeSerializer(IEdmTypeReference edmType)
    {
        if (edmType.IsEntity())
        {
            return _customODataEntityTypeSerializer;
        }

        return base.GetEdmTypeSerializer(edmType);
    }
}




public class CustomODataEntityTypeSerializer : ODataEntityTypeSerializer
{
    public CustomODataEntityTypeSerializer(ODataSerializerProvider serializerProvider) : base(serializerProvider)
    {
    }

    public override void WriteObjectInline(object graph, IEdmTypeReference expectedType, ODataWriter writer, ODataSerializerContext writeContext)
    {
    //here it is which place I need to be fired for all requests
    }
}

registration:

             var odataFormatters = ODataMediaTypeFormatters.Create(new CustomDefaultODataSerializerProvider(), new DefaultODataDeserializerProvider());
         config.Formatters.InsertRange(0, odataFormatters);

This is the header that works:

Accept:application/atomsvc+xml;q=0.8, application/json;odata=verbose;q=0.5, */*;q=0.1
Accept-Encoding:gzip, deflate, sdch, br Accept-Language:en-US,en;q=0.8 Connection:keep-alive

And this is the header that does not work:

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

Accept-Encoding:gzip, deflate, sdch, br Accept-Language:en-US,en;q=0.8 Cache-Control:no-cache Connection:keep-alive

Start with CustomDefaultODataSerializerProvider, CustomODataEntityTypeSerializer, and the ODataMediaTypeFormatters registration shown in the issue. Reproduce the requests with the two Accept headers and trace formatter and serializer selection; done means identifying why WriteObjectInline is reached for one request but not the other and documenting the supported response behavior.
