I think you don't use the post metrhod the right way. You could try something like that:

onSubmit(event,username,password) {
  this.creds = {
    'Email': 'harikrishna@gmail.com',
    'Password': '01010','RememberMe': true
  }

  this.headers = new Headers();
  this.headers.append('Content-Type', 'application/json');

  this.http.post('http://xyz/api/Users/Login', 
                 JSON.stringify(this.creds),
                 { headers: headers });
}

You invert parameters. The second parameter corresponds to the content to send into the POST and should be defined as string. Objects aren't supported yet at this level. See this issue: https://github.com/angular/angular/issues/6538.

If you want to set specific headers, you need to add the Headers object within the third parameter of the post method.

Otherwise, I think the withCredentials property is related to CORS if you want to send cookies within cross domain requests. You can have a look at this link for more details:
