I want to be able to set the value of my primary key to an auto increment number. At the moment it generates a random key such as 13917c50-6b8c-4405-82ce...
I want to be able to tell the system "Hey, I want request number to start at 1 (or 1000 or whatever) and auto increment every time a record is saved."
public class Request
{
[Key]
public string request_no { get; set; }
I expect, as a record is saved, for a request number of my choosing to be auto generated.
Use DatabaseGenerated attribute:
public class Request
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int request_no { get; set; }
}
Also if you want to create seed for request_no then you should use custom database initializer and execute DBCC CHECKIDENT query:
DBCC CHECKIDENT ('Request', RESEED, 1000)
