Getting error in C# for Azure Function app

Can anyone help me fix these errors?

#r "Newtonsoft.Json"
#r "Microsoft.WindowsAzure.Storage"

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;
using Microsoft.WindowsAzure.Storage.Table;

public static async Task<IActionResult> Run
              (HttpRequest req,
               CloudTable objUserProfileTable,
               ILogger log)
{
    log.LogInformation("C# HTTP trigger function processed a request.");

    string firstname = null, lastname = null;

    string requestBody = await new 
    StreamReader(req.Body).ReadToEndAsync();

    dynamic inputJson = JsonConvert.DeserializeObject(requestBody);
    firstname = firstname ?? inputJson?.firstname;
    lastname = inputJson?.lastname;

    UserProfile objUserProfile = new UserProfile(firstname, lastname) ;

    TableOperation objTblOperationInsert = 
    TableOperation.Insert(objUserProfile);
    await objUserProfileTable.ExecuteAsync(objTblOperationInsert);

    return (lastname + firstname) != null 
    ? (ActionResult)new OkObjectResult($"Hello, {firstname + " " + lastname}")
        :new BadRequestObjectResult("Please pass a name on the query" + "string or in the request body");
}

class UserProfile : TableEntity
{
    public UserProfile(string firstName, string lastName)
    {
        this.PartitionKey = "p1";
        this.RowKey = Guid.NewGuid().ToString();
        this.FirstName = firstName;
        this.LastName = lastName;
    }

    UserProfile() {}

    public string FirstName { get; set; }
    public string LastName { get; set; }
}

I get these errors:
