Dear Experts,
Just let me know is the following code executed as asynchronously ?
My Code is shown below

public class CompanyController : Controller
   {
public delegate void CompanyAuditRecordKeeper(CompanyModel company, string operationType);
    public ActionResult Create(CompanyModel oCompany)
        {
            //some code


            //I Used below code for asynchoronus call AddCompanyAuditRecords
           //some code
            CompanyAuditRecordKeeper auditkeeper = new CompanyAuditRecordKeeper(AddCompanyAuditRecords);
            auditkeeper.BeginInvoke(oCompany, "I", null, null);

            return Json("", JsonRequestBehavior.AllowGet);
        }
         public void AddCompanyAuditRecords(CompanyModel company, string operationType)
        {
         //  some code goes here

        }
  }

My Question is Will the 'AddCompanyAuditRecords' function be executed asynchronously?

Although I read it from MSDN that it will be executed asynchronously.From the following link
https://msdn.microsoft.com/en-us/library/2e08f6yc(v=vs.110).aspx

My confusion arises because an expert said me that it won't executed asynchronously please let me know?
