I like
http://www.codeproject.com/Articles/34491/Implementing-Audit-Trail-using-Entity-Framework-Pa
but it is not for MVC4.

What easy "ASP.net MVC4 History Log"
solution do you have so the below works ?

Steps
 1. user clicks SAVE on Edit.cshtml as normal
 2. below code runs as normal
 3. somehow (via code or MSSQL database trigger) it writes
    only changed values to my "AUDIT_LOG" database table
-----------------------------------------------------------------
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Edit(MAINT_WORK_REQ maint_work_req)
        {
            if (ModelState.IsValid)
            {
                db.Entry(maint_work_req).State = EntityState.Modified;
                try
                {
                    //OurTechSignature_Date
                    if (maint_work_req.OurTechSignature_Date == null)
                    {
                        if (Request["Signature_Tech_Checked"].Contains("true"))
                        {
                            var context = new UsersContext();
                            UserProfile myProfile = context.UserProfiles.SingleOrDefault(u => u.UserName == User.Identity.Name);
                            maint_work_req.OurTechSignature_Date = myProfile.FirstName + " " + myProfile.LastName + " " + DateTime.Now.ToShortDateString();
                        }
                    }

                    var context2 = new UsersContext();
                    UserProfile myProfile2 = context2.UserProfiles.SingleOrDefault(u => u.UserName == User.Identity.Name);
                    maint_work_req.LastModifiedDate = DateTime.Now;
                    maint_work_req.LastModifiedBy = myProfile2.FirstName + " " + myProfile2.LastName;

                    db.SaveChanges();
                    .... something like "db.SaveAuditLog()" here
