💥			PROBLEM ATM: My iMac is so old that it can't take macOS 10.14. Therefore, it can't take VS for Mac 2022. Therefore, I can't update docs for UI changes. I'm waiting on Aquent to send me a late-model Mac. This entry will be addressed as soon as that Mac arrives. 🚚 VS for Mac 2022 is still in preview for 6.0. Search for "preview" to isolate and update the guidance. It's probably best to keep the text in the docs where it cross-links to content on how to use the Preview channel and just comment it out. This is going to be recurring guidance each time VS for Mac goes into preview for an upcoming release, and it will be simpler to keep the guidance there in an unrendered state between releases. Note that this update includes Blazor node docs and the Blazor-SignalR tutorial.

[fiyazbinhasan]

Hey @guardrex! I can see some cool stuff coming in Blazor 6.0 docs. Do you need an extra hand? Let me know how you are planning to resolve these. Thanks 😺

[guardrex]

Yes, @fiyazbinhasan ... that would be great to have help with the updates. They're on hold right at the moment for two reasons ...

• We've been burned a few times in the past documenting upcoming release features, particularly the large features (new topics usually) during preview due to engineering churn. We document something well ... the engineers take feedback and think things over and then decide to change the bits ... the new docs are then stale and must be revisited and updated. If the changes are small, no problem. Sometimes tho, the changes are LARGE. It's time-consuming and costly 💰 when this happens, so we generally hold off until RC1 (or close to RC1) before documenting most upcoming release features. We're still a couple of months away from RC1. Historically, there's been plenty of time between RC1 and GA to get everything documented, too. There's usually at least two full months, often three.
• I'm not aware yet on a few of these if the PU wants to provide content, possibly code, for the doc updates. For most of these, text and code is readily available from the PU issue/PR and DR's preview blog posts. For most of these, the PU will be quite happy not to have to provide anything ... indeed, the less they hear about docs the better 🙈😆.

When the time comes to work on these, the plan is to use the individual tracking issues (first column ☝️) to decide where the content will live (e.g., section of a topic or new topic, titling, metadata, etc.) and what sort of example code would be good. To speed up working example code in, what we'll probably do is place code directly into the topics and then I'll circle around after GA and move that code into the snippet sample apps.

I'll ping u back here when I have more info on the plan for these.

[fiyazbinhasan]

I'll ping u back here when I have more info on the plan for these.

Sure thing @guardrex!

Thanks for explaining everything I need to know. One thing though, how do you type all of these so fast? 🙀

[guardrex]

They installed an electric shock feature on my PC. If I don't answer a comment within 37 seconds, they hit me with 240V! ⚡😝

Seriously tho, I do spend a lot of time ... too much probably ... on the PC.

[guardrex]

@fiyazbinhasan ... I haven't forgotten about your offer to help. Currently, I'm working through a small batch of mostly straightforward issues that aren't taking long to resolve. I'm almost done with them. I'll have this subset addressed within a couple of weeks. We're in good shape right now with the workload. I'll let you know if help is needed and/or I come to larger issues that require a lot more work.

[fiyazbinhasan]

Aye, aye, captain! 😄

[TanayParikh]

Hey @guardrex, just wanted to mention we don't need docs for Blazor Server: Specific component for dealing with large amounts of text data (InputTextArea) as we've decided not to add it to the core framework (but instead put up a sample in aspnet/ASPLabs).
