ISTM that it would be nice if the scaffolding could pick up on this stuff from Sql Server. For example, if the field is "Not Null" then the form should default to "[Required]." This would not have the result of making it SS specific, since you would only be supplying a different default, if nothing is specified. This would have the result of it being possible to make an instant app with no programming.
This was a very useful presentation. Kudos and thanks.
