By default, Scaffolding a table with an auto-increment field adds:
.ValueGeneratedNever();To the field in the Model Builder. This will cause an automatic value NOT to be generated. This needs to be removed.
Also, we need to add:
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int? TemplateId { get; set; }To the item – and ensure it is a nullable int. https://docs.microsoft.com/en-us/ef/core/modeling/generated-properties …
I’ve researched this several times now and keep forgetting the results. So, putting it here to record it for next time. What is the difference and usage for c# interfaces, virtual and abstract classes and methods? And where do you use them?
An interface specifies a contract.
Don’t get me wrong, I know I’m a grumpy old bastard sometimes, and one of my character flaws is not admitting I’m wrong. But in the face of irrefutable proof that I’m wrong, I’ll most often accede the point.
However, one thing that gets my goat is when someone says something that is clearly wrong, is then proven wrong by stating the facts, then goes on to continue to rant about being treated disrespectfully rather than admit they were wrong in the first place!
If you’re going to act like a dick, expect to be treated with the same amount of respect as you gave!…
This next build is taking me a long time to do. Started it in February 2018 while I was still doing the instrument making course at TAFE. My goal was and is to make the entire thing at home, which I have achieved so far. It’s taken so long because of a) lack of motivation and time and b) I have had to build lots of jigs and buy more tools in order to complete the job.
As of October 2019, the sound box is now complete. Papua New Guinea Rosewood back and sides with Silver Quandong top. The bindings and end graft are Tassie Blackwood and maple.…
Today’s Dilbert calendar strip got me thinking…imagine if it were possible to upload the contents of your brain for offline storage.
Wouldn’t it be great to have a backup of all your thoughts, memories and things you have learned over the years? Just like when your hard drive crashes on your computer, you might be able to restore your brain to a point in time. How useful would that be for people who get dementia or Alzheimers?
Even if you couldn’t restore to your biological brain mass, perhaps it might be possible to access those memories offline. In the Chrysler Club we often lament the loss of knowledge as former workers at Chrysler pass away and that history is gone forever.…
“Life a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones.” – Marcus Aurelius (Roman Emperor and Philosopher)…
Listening to the Luthier on Luthier podcast this morning about Jay Lichty and his guitars. Interesting the way they set up their business and ability to pick guitars based on tone and price. Some great designs too. lichtyguitars.com…
Not as easy as you would think, once installed, the service wouldn’t start, then I couldn’t log on (Access Denied) then I couldn’t connect remotely.

I have installed the Data-Tier Application Framework and SQL Server Data Tools for VS 2017 . I created a solution then returned to it a week later and the SSIS toolbox had disappeared.
I opened the toolbox window using View -> Toolbox but it was empty.
To get the SSIS toolbox back, right-click on the SSIS design surface in the project and select SSIS Toolbox – hey presto! it reappears.
