c# - MVC 6 Post action parameter is null -

i have mvc 6 application , separate mvc 6 webapi service.

i send object application using code:

this view part of it:

the client sends webapi service:

where parameter null:

in fiddler log 0 content-length:

what else should set?

it important set encoding , media type of stringcontent. if use postasjsonasync take care of part - unfortunately can't use in dnx.

so proper code of client:

  string content = newtonsoft.json.jsonconvert.serializeobject(blog);   httpresponsemessage response = await client.postasync("api/values", new stringcontent(content, encoding.utf8,"application/json"));
