Third option would be Blazor Server but I wouldn't consider that here if you need more or less a static site.

✅ ASP.NET open project

Then you have two choices, MVC which is more boilerplate or Razor pages which is newer and requires typically fewer files and boilerplate.

So to solve your problem, let EF Core track your fetched items properly from fetching the data

Also don't use SaveChangesAsync as long as you really don't know what the consequences are

So you can also remove this code:

_mainDbContext.WorkItems.Attach(existingWorkItem);
_mainDbContext.Entry(existingWorkItem).State = EntityState.Modified;

_mainDbContext.WorkItems.Attach(existingWorkItem);
_mainDbContext.Entry(existingWorkItem).State = EntityState.Modified;

So to solve it, you can fetch the original items in a tracked way and modify them, so EF Core knows about it

But the real problem here seems to be, that you first fetch existing items without tracking by EF Core, then you modify them, then you attach them to the context and change the state. The issue is probably that at the moment in your application you already have that item tracked by EF Core and that then causes issues.

Because that's what EF Core is complaining about right now

So the first thing you need to make sure is through debugging is that you don't have two WorkItem entities with the same WorkItemId
