Should I use a Guid and Guid.Empty or a nullable Guid?

I wish this help you If the parameter can be null on the T-Sql side, then I think Guid? is a more natural fit. Especially when used with ADO.NET parameterized queries, nullable types are conveniently translated to DBNull.Value when their value is null. If you were to use Guid.Empty to indicate null, then you'd need to check for that condition and explicitly pass DBNull.Value to your command/query. E.g.: command.Parameters.AddWithValue("@guid", myNullableGuid)
command.Parameters.AddWithValue("@guid",
myGuid == Guid.Empty ? DBNull.Value : myGuid)
