I have a SQL table with a datetime field of Version_Date as a primary key, I can see its data saved as this format: "2018-09-26 00:00:00 000",

Now, from the razor view with a update when I change this field from razor view and save it, here is the code in controller:

[HttpPost]

[ValidateAntiForgeryToken]

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "Version_Date,xxxx")] tbl_Version_Information tbl_Version)

{
 
if (ModelState.IsValid)
            {
               // Date(tbl_Version.Version_Date) = xxx //I need to do some changes here_
                db.Entry(tbl_Version).State = EntityState.Modified;               
                db.SaveChanges();
    }}

Now, when I changed the Version_Date field from razor view and save it, I got this error:

System.Data.Entity.Infrastructure.DbUpdateConcurrencyException: 'Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded

After some searches, I found the error caused by the Version_Date field since it is a Primary key in SQL table with millisecond portion of data, how to make this update working?

Thanks a lot,
