Store update, insert, or delete statement affected an unexpected number of rows (0) EntityFramework [duplicate]

Answer 1

In my case, I had a composite key and was trying to update part of it (3 columns constitutes a composite key, out of which i was updating 3rd column only) but EF didn't allow changing key values for the same object, I achieved updating the record through:

Context.Database.ExecuteSqlCommand(udpateCommand);
