How do I increase maximum limit of video upload in MVC ASP.NET

Hello

I've been trying to upload Mp4 videos which have large space in my MVC project and it gives me an error, it only allows videos that are smaller then 3MB. Even if i change the if statement below e.g

if(videofile.ContentLength< 104857600)

still it doesn't solve my problem.

Please help

What I have tried:

videofilesDB db =new videofilesDB();
        GET: MVCupload
        public ActionResult Index()
        {
           return View();
        }
        public ActionResult Index(HttpPostedFileBase videofile)
        {
            if(videofile!=null)
            {
                string filename = Path.GetFileName(videofile.FileName);
                if(videofile.ContentLength< 104857600)
                {
                    videofile.SaveAs(Server.MapPath("/Videofiles/" + filename));

                    string mainconn = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
                    SqlConnection sqlconn = new SqlConnection(mainconn);
                    string sqlquery = "insert into [dbo].[videofiles] values (@Vname,@Vpath)";
                    SqlCommand sqlcomm = new SqlCommand(sqlquery, sqlconn);
                    sqlconn.Open();
                    sqlcomm.Parameters.AddWithValue("@Vname", filename);
                    sqlcomm.Parameters.AddWithValue("@Vpath","/Videofiles/" + filename);
                    sqlcomm.ExecuteNonQuery();
                    sqlconn.Close();
                    ViewData["Message"] = "Record Saved Successfully!";

                }
            }
            return View("Index");
