Concurrency Field - Not Reacting to Parameters Changing

[crazyfox55]

blazor-samples/8.0/BlazorWebAppEFCore/Components/ConcurrencyField.razor

Lines 36 to 47 in d000234

	protected override void OnInitialized()
	{
	if (Property is not null && DbModel is not null)
	{
	property = Property(DbModel);
	if (Model is not null && property is not null)
	{
	IsDelta = !Property(Model).Equals(property);
	}
	}
	}

This should be using the OnParametersSet, such that when the DbModel changes the property is checked again. Also none of the properties of the Contact have ConcurrencyCheck attributes, so the newest EF core will not automatically fail. I suggest adding the ConcurrencyCheck attribute to at least one property or every property because the UI implies the whole object is checked for concurrency.

Thanks for the report, @crazyfox55.

I'm moving this over to our actual working repo. We ask devs to open issues for us using the Open a documentation issue link/feedback form at the bottom of an article. Issues here are usually just for patch changes, and this one will need the product unit to get involved. Use of the automatic form from the bottom of an article adds metadata to the GitHub issue that cross-links the topic and pings the author automatically for a faster response.

Moved to dotnet/AspNetCore.Docs#33943.
