You should be able to retrieve a claims like this within your controller

var identity = HttpContext.User.Identity as ClaimsIdentity;
if (identity != null)
{
    IEnumerable<Claim> claims = identity.Claims; 
    // or
    identity.FindFirst("ClaimName").Value;

}
If you wanted, you could write extension methods for the IPrincipal interface and retrieve claims using the code above, then retrieve them using (for example)

HttpContext.User.Identity.MethodName();

// Cast to ClaimsIdentity.
var identity = HttpContext.User.Identity as ClaimsIdentity;

// Gets list of claims.
IEnumerable<Claim> claim = identity.Claims; 

// Gets name from claims. Generally it's an email address.
var usernameClaim = claim
    .Where(x => x.Type == ClaimTypes.Name)
    .FirstOrDefault();

// Finds user.
var userName = await _userManager
    .FindByNameAsync(usernameClaim.Value);

if (userName == null)
{
    return BadRequest();
}

// The rest of your code goes here...
