Provide an option to enable enhanced form handling by default

[danroth27]

We disabled enhanced form handling by default in .NET 8 because of concerns that posting a form could fail if it's directed at a non-Blazor endpoint and a POST request cannot safely by retried without the enhancement. But for most cases enhanced form handling is what you want. We should consider providing a global option to enable enhanced form handling for users that are familiar with the feature and want the convenient default behavior.

Thanks for contacting us.

We're moving this issue to the .NET 9 Planning milestone for future evaluation / consideration. We would like to keep this around to collect more feedback, which can help us with prioritizing this work. We will re-evaluate this issue, during our next planning meeting(s).
If we later determine, that the issue has no community involvement, or it's very rare and low-impact issue, we will close it - so that the team can focus on more important and high impact issues.

HI @Bartmax. I believe @SteveSandersonMS's response in that comment was specific to enhanced navigation. Enhanced form handling in .NET 8 RC2 is now off by default and requires using the data-enhance attribute to enable it on a per-form basis.

I see. Are those two different things? 🤔 I always mentioned one or another as if they were the same thing.

I'm confused.

@Bartmax Enhanced navigation and enhanced form handling use the same mechanics of intercepting the page navigation and doing a fetch request instead. But the difference is that an enhanced navigation is a GET request, which can be safely retried if needed as a normal navigation, but an enhanced form post is typically a POST request, which will simply fail if you try to do an enhanced form post to a non-Blazor endpoint.

Hi Dan, when you say Global option, is it VS template or adding a piece of code in i.e. App.razor?
And is a piece of code available right now that does it for the whole application?

I was thinking a code option.

is a piece of code available right now that does it for the whole application?

Nope, not that I know of. Adding an API for this is what this issue is tracking.
