IgnoreOnInsert not working for RowVersion property

As shown in https://docs.servicestack.net/autoquery-crud#optimistic-concurrency I would like to define a Create and Update service that inherits from an underlying type as follows:

[Route("/api/app/user-setting", "POST")]
public class CreateUserSetting : UserSetting, ICreateDb<UserSetting>, IReturn<GuidResponse>, IPost

[Route("/api/app/user-setting/{Id}", "PUT")]
public class UpdateUserSetting : UserSetting, IUpdateDb<UserSetting>, IReturn<GuidResponse>, IPut

public class UserSetting : MyAuditBase
    [DataMember, Required]
    public Guid Id { get; set; }

    [DataMember, Required]
    public Guid AccountId { get; set; }

    [DataMember, Required]
    public string KeyName { get; set; } = null!;

    [DataMember, Required]
    public string KeyValue { get; set; } = null!;

    public string? Description { get; set; }

    [DataMember, Required]
    public ulong RowVersion { get; set; }

The corresponding database table is defined as

CREATE TABLE App.UserSetting (

    -- referential
    IndexId               INT IDENTITY(1,1),

    -- Lookup data
    AccountId             UNIQUEIDENTIFIER   NOT NULL,
    KeyName               NVARCHAR(60)       NOT NULL,
    KeyValue              NVARCHAR(240)      NOT NULL,
    Description           NVARCHAR(240)      NULL,
    DataEventRv           ROWVERSION         NOT NULL,
    DataEventOn           DATETIME2          NOT NULL,
    DataEventId           TINYINT            NOT NULL, 
    DataEventBy           UNIQUEIDENTIFIER   NOT NULL,

The MyAuditBase class handles the autopopulation of the audit fields (DataEventId, DataEventOn and DataEventBy). The Update service is working correctly.

However, when calling the Create service the Rowversion (DataEventRv) is not being ignored on insert, so it causes a database (MSSSQL) exception:

Create Request (POST):
  "Id": "00000000000000000000000000000000",
  "AccountId": "603296de63abec11b596482ae316d296",
  "KeyName": "K2",
  "KeyValue": "V2",
  "Description": "D2",
  "RowVersion": 0

Error Response:
  "id": "00000000000000000000000000000000",
  "responseStatus": {
    "errorCode": "SqlException",
    "message": "Cannot insert an explicit value into a timestamp column. Use INSERT with a column list to exclude the timestamp column, or insert a DEFAULT into the timestamp column.",
    "stackTrace": null,
    "errors": [],
    "meta": null

The output from using PrintSQL, below, shows that a value is being inserted for the RowVersion (DataEventRv):

SQL: INSERT INTO "App"."UserSetting" ("AccountId","KeyName","KeyValue","Description","DataEventRv","DataEventId","DataEventOn","DataEventBy") 
VALUES (@AccountId,@KeyName,@KeyValue,@Description,@DataEventRv,@DataEventId,@DataEventOn,@DataEventBy)
PARAMS: @AccountId=603296de-63ab-ec11-b596-482ae316d296, @KeyName=K2, @KeyValue=V2, @Description=D2, @DataEventRv=0, @DataEventId=1, 
@DataEventOn=2022-03-30 03:58:09, @DataEventBy=603296de-63ab-ec11-b596-482ae316d296

Is it possible to have RowVersion ignored on insert, or is it using a special convention that bypasses the ignore attribute?

Running under windows with ServiceStack 6.0.3; C#10; Net6; MSSQL 2019

No, RowVersion is a special RDBMS feature for asserting optimistic concurrency that can’t be disabled like other RDBMS columns. You’ll need to remove the column if you don’t want it.

Yes, I suspected as much. Oh well, no harm in asking, thank you for the fast response.
