Internal review link for the System namespace

Notes on warnings:

• ECMA2Yaml_UidAssembly_NotMatched: This is an engineering issue, and is accepted as a bug. We expect a fix in an upcoming sprint.
• ECMA2Yaml_MemberNameAndSignature_NotUnique: This is also an engineering issue.
• UidNotFound: Some of these are external, and filter out polly and redis #4218 filters them out. Some of the others should be removed from the binaries repo. I'm working with the team on those, but it will probably be preview 5 before they are addressed. Others may also be filtered out once we have more feedback from the product team.

How do I review this? lol

[mairaw]

Usually I start with one link and then navigate through some of the changes. Usually I scanned the diff to see if the changes I was seeing were expected more than looking at the review site.

According to @RussKie there should be a TaskDialog API, but I'm not seeing it. I only see a .NET 5.0 Preview 1 moniker?

[mairaw]

The moniker description is only changed when the content goes live.

The moniker description is only changed when the content goes live.

The preview 3 content went live yesterday, but that moniker doesn't show up either.

The TaskDialog class is in this PR.

What will happen is the content goes live once we merge this (and merge to live, and it builds). The moniker description (changing to Preview 4) is done in the portal.

During the previews, we'll reuse one moniker, and only have the latest version live.

Thanks for the reminder @gewarren I just edited the current moniker to "Preview 3"

I did notice (even on the published site) that the platform extensions list .net 5 preview 1 only. I think that is incorrect. I would assume these APIs work on all .NET Core versions too, which means the platform extensions should have more than a single entry.

ping @mairaw for insight on the preview comment.

[mairaw]

We didn't have System.Windows.Forms.dll as part of the extensions set before.

[mairaw]

And API Catalog only shows that as part of 3.0 (I guess we moved to shared framework instead for docs): https://apisof.net/catalog/System.Windows.Forms.Control.CreateControl()
